The Additional Harbour Crossing as currently proposed is a pair of tunnels containing six traffic lanes between the motorway at Esmonde Rd rejoining it at Spaghetti Junction [The CMJ] in the city. The publicly available schemes also show additional rail tunnels between Akoranga and Wynyard Quarter, but no connecting network for any trains to actually use. It is clear to see the appeal for NZTA of straightening and simplifying SH1 past the bridge, but the outcomes for the city are much less certain. Below for example is version T1:
Clearly this or the other versions that date from 2010 are not the current versions NZTA are developing now, but until new versions are released these are still worth looking at in some detail as neither the various physical constraints or the overall aims that drive these options have changed. The options can be seen here.
Considering these there are several high altitude observations I think are important to begin with:
- This will be the most expensive urban transport project ever undertaken in NZ; claimed to be $4-$6 billion. Two to three times the cost of the CRL.
- Not least because of the massive cost it is extremely unlikely that both sets of tunnels and systems would be undertaken at the same time. They will be staged; one will precede the other.
- The road scheme is essentially a SH1 bridge bypass, and therefore optimises through traffic, however it does not make any new connection that is not currently available nor in fact any increase in capacity on SH1.
- There is little spare capacity in the CMJ for additional vehicles so the new connection will remain the current three lanes north and a reduction from four to three lanes south.
- Essentially the bridge becomes a massive on/off ramp for city traffic and unless and until the rail tunnels and line are built more buses on bus lanes across the bridge will be the PT part of the project.
Here’s the set of variations currently available for the city end, all versions involve four tunnels under Victoria Park [3 new ones]:
All schemes also involve massive new interchanges on new reclamations at the North Shore end with flyovers and multiple connections between crossings, not unlike the new interchange at Waterview currently being built. Like the outcomes for traffic on North Shore local roads, the impacts of this project will be neither small nor all positive north of the bridge. However for this post I just want to focus on the city-side implications.
Assuming the road crossing is built first, which is consistent with assertions by politicians and officials with phrases like it will be ‘future proofed for rail’, as well as the lack of any real work yet on a rail crossing, it is worth asking exactly where will the new traffic enabled by the extra capacity across the harbour go once in the city?
Because the new crossing plugs directly into the CMJ, three lanes in and three lanes out, and because there are no planned increases in capacity through the CMJ, nor any space for any without further massive tunnelling, in effect the new capacity will be all on the bridge, so coming from the Shore this new traffic will all have to be accommodated by just three off ramps [same in reverse heading north]:
- Cook St; with new direct connections through Victoria Park
- Fanshawe St, especially for buses on new bus lanes
- Shelly Beach Rd, and then on to Jervois and Ponsonby Rds.
None of these exits can accommodate any increasing in traffic well, or without considerable disbenefit, especially if that increase in traffic is large.
- Cook St is pointed directly at the heart of the city, so this contradicts policy of reducing vehicle volumes in the city centre and is likely to infarct daily at the peaks as Cook St is close and perpendicular to Hobson and Nelson Sts which serve the Southern and Northwestern motorway flows. Gridlock is likely at the controlled intersections unable to handle large and peaky traffic volumes to and from these motorways. Additionally land use in this area is changing and intensifying making it even less suitable for the high speed motorway offramp it already hosts.
- Fanshawe will have reduced capacity for general traffic as a multilane Busway will be required to take the increased bus volumes from the bridge, and anyway is already at capacity at the peaks.
- Shelly Beach Rd is a narrow residential street not suited to the high volumes and high speeds it already suffers from the bridge now. Furthermore there is no benefit and little capacity for the streets beyond Shelly Beach Rd, particularly Jervois and Ponsonby Rds for a large increase in vehicle volumes.
Nonetheless, here are the forecasts they have come up with, Shelly Beach Rd with a 63% increase, is basically filled with bridge traffic by 2026 and the new crossing:
20,300 additional cars modelled for Fanshawe + Cook St with the AWHC option (assume that is all day on a weekday?). Even at the best sorts of turnover that would require around 10,000+ new carpark places. The downtown carpark has 1890 spaces. So where exactly do we put six new downtown carpark buildings? And what six streets get sacrificed to feed them?
20,300 cars carry perhaps 25,000 people. The CRL at capacity will carry that entire amount in 40 minutes. As could a North Shore rail line of similar specification. If the net outcome of this project is to take 20,000 commuters to midtown, why not do it with rapid transit at a third the cost with none of the traffic congestion?
“The significant increase in traffic movements conflict with many of the aspirations outlined in current Council policies, strategies, frameworks and master plans.”
–P 65 Additional Waitemata Harbour Crossing Network Plan, NZTA, 2010.
Obviously these higher traffic volumes are not good for every pedestrian, resident, and general city user in these areas but there is one other group that this situation in particular is going to make miserable, and that’s the motorist. There is a word for all this additional driving everywhere on city streets: congestion. Yup this increase in capacity across the harbour may speed that part of the journey but it’s going to make arriving anywhere in the city in your car much more hellish than it is now. And don’t even think about finding or affording somewhere to park.
What NZTA’s consultants say about this:
The increased traffic flows through St Marys Bay on both Shelley Beach rd and Curran St look to lead to particularly poor and unfixable outcomes:
It seems optimistic to say that because there are cafes, and strongly increasing pedestrian volumes, on Ponsonby Rd, that drivers won’t try to drive there, especially if other bridge exits are controlled or too busy. After all the first rule of urban traffic is that it will expand to wherever it is allowed to go. So, in the end, taking measures to dis-incentivise drivers to use these exits, is the consultant’s advice:
It does seem kind of odd to spend $4-6 billion to increase capacity across the harbour only to then introduce other measures to try to stop people using it.
And it won’t be just parking, there’s also likely to be tolls, it appears the model says they can pretty much eliminate the traffic problem with an $8 toll!:
If only there was a way to enable more trips without inducing more and more cars to also be driven into the crowded city streets. After all the City Centre has been growing strongly without adding more cars most of this century:
In fact it looks like we are already at or even above the limit of desirable vehicle numbers in the city, and future developments like replacing car access to Queen St with Light Rail are likely to make even current numbers face pressure.
Additionally there is an issue with bus volumes as well as car numbers on the city streets, even though the New Bus Network, the CRL, and Light Rail, if it happens, will reduce bus numbers from other parts of the city, there is certainly a limit to the numbers of buses from the Shore that can be comfortably accommodated too. Below is the predicted year of maximum bus capacity at major entry points to the city. The role of the CRL in reducing bus number pressure from the Isthmus is obvious, so why not do the same thing for buses from the Shore?
So perhaps the answer is to reverse the assumed staging and build the rail Rapid Transit tunnels first, leaving space for the road crossing to come later. This certainly looks physically possible in the maps above. This would enable all of those possible trips across the Harbour that NZTA identifies to still be served but without any of the traffic disbenefits that so clearly dog the road only crossing. In terms of people capacity two rail tracks can carry twice the volume of six traffic lanes. Furthermore it can be built without disturbing the current crossing and its connections. And rail crossings have proven in the past to be good alternative routes in an emergency.
This would add the real resilience of a whole other high capacity mode across the Harbour instead of simply more of the same. It would make our Harbour infrastructure more closely resemble Sydney’s where most of the heavy lifting in terms of people numbers is done by Rapid Transit, as shown below. We already have ferries, buses, and cars bringing people across, isn’t it time we added the particular efficiency of electric rail?
It seems particularly clear that whatever we add next really can’t involve trying to shove ever more vehicles [cars and buses] onto our crowded city streets; that will simple hold everyone up.
All the information above was gleaned from the work done some six years ago for NZTA, from here, and Auckland has moved on a great deal from where it was then. Among other things that have been proven recently is that when we are offered a high quality rail system we will use it. We are also discovering the value of our City Centre as a place to live, and work, and just be in, and how this is only possible to continue this improvement with fewer cars on every street. We certainly believe that there are more options for a far greater Auckland than the simple binary ones studied above: the road crossing ‘future proofed’ for rail, or the ‘Do Minimum’ which is nothing.
So we have asked, as part of the Auckland Transport Alignment Process, for a Rapid Transit crossing as the next additional crossing to be modelled too. So we can compare the status quo with the road crossing, and with a Rapid Transit crossing separately. Additionally we know that AT are now working on how various rail systems could work so in time there will be properly developed rail options to compare with the road one.
There is time as well as the need to get this right, the Western Ring Route will begin to become more complete next year with the opening of the Waterview tunnels, and that whole multi billion dollar system is of course an alternative harbour crossing system and will alter both the performance of both the Bridge and the CMJ. Similarly decisions about AT’s proposed LRT system too has a bearing on options, as will the opening of the CRL next decade. Not least because the addition of these high quality systems will make movement through the city without a car much more common, as is the case in many overseas cities of Auckland’s size and quality.
The road crossing looks very much like an extremely expensive ‘nice to have’, that duplicates and tidies up the State Highway route, something to add when the missing alternatives have been built and there is spare budget to spend on duplication. Because on balance the road first additional crossing proposal really achieves little more than this:
While the answers to this question are largely sell-evident, it’s great that NZTA have recently released a summary of their view: Benefits of Investing in Cycling in New Zealand.
Follow the link for the full PDF, below is a summary of the seven ways NZTA have identified as beneficial. Followed up by a few images that do the same thing.
1. Investing in cycling is giving people what they want
People want cycling infrastructure. Many people say they’d like to cycle more, especially if separated cycling infrastructure was provided.
2. Cycling makes towns and cities really liveable
Cycling improves quality of life in towns and cities. ‘Quality of life’ rankings consistently show bike-friendly cities at the top.
3. Cycling makes travelling around urban areas better for everyone
More people cycling potentially improves traffic flow so travel times are shorter, more predictable and reliable, and the transport network performs better. Bicycles are considered to impose 95 percent less impact on travel flow than an average car.
Getting just a few people onto bikes can15 make a di erence to tra c ows. On the congested 5km Petone to Ngauranga section of State Highway 2, for example, research suggests that only 10-30 vehicles out of the 250-280 vehicles occupying the space at congested times are causing the congestion.16 Evaluation of Hastings’ iWay cycling network indicates there was a 3.6 percent reduction in tra c volumes soon after it was built.17
4. Cycling is great for the local economy
Cycling saves people money to spend in their local communities. With no fuel, registration, warrant of fitness and parking costs, and much lower purchasing, maintenance and insurance costs compared to operating a car, people who cycle have more money to spend on other things.
Cycling potentially also boosts retail spend. Various studies have shown that cycling infrastructure can lead to an increase in retail sales.25 People who cycle have been found to be more likely to stop and visit shops more often, and to spend more money at those shops over time, than people who drive.26 Cycleways that run past shop doors can be a very good thing for retailers.
5. More cycling means reduced costs for the council
An increase in cycling saves councils money. This is especially clear where populations are expected to grow. In Christchurch, for example, where 50,000 additional car trips per day are predicted in the city by 2041 unless there is a mode shift to walking, cycling and public transport31, more cycling would mean reduced costs for additional road capacity, maintenance and operations.
6. Cycling is great for the environment overall
A small reduction in short vehicle trips potentially generates signi cant reduction in carbon emissions. Shifting 5 percent of car trips to bicycle could reduce emission impacts by up to 8 percent.33 Similarly, reducing trips by car can reduce the amount of other air pollutants.
7. Cycling makes people healthier and more productive
Cycling reduces the incidence of a range of serious illnesses.
In New Zealand, physical inactivity contributes to around 8 percent of all deaths37, and one in three adults and one in ve children are overweight38. The Ministry of Health reports that only 50.5 percent of New Zealand adults are regarded as sufficiently active for health benefits and physical inactivity is the second leading risk factor of disability adjusted life years.
There are many reasons to be concerned about the plan to add more road lanes across Auckland’s Waitemata Harbour: from the extreme cost of building such big tunnels and interchanges [$5-$6 billion and four times as much as just building rail tunnels], to the undesirable flooding of city streets and North Shore local roads with even more cars, to the increase in air pollution and carbon emission this will create, the loss of valuable city land to expanded on and off ramps and parking structures, to the impact on the harbour of exhaust stacks and a supersized motorway on the Shore, to the pressure this will put on the rest of the motorway system particularly through the narrow throat of Spaghetti Junction. It is both the most expensive and least efficient way to add capacity across this route, and if resilience is the aim then the double-down on reliance the motorway system rather works against this. This one project will simply crowd out any other changes we could make of scale in Auckland or the country for years; yet it changes almost nothing; it simply enables more vehicles to travel across a short point in the middle of the city, yet this is by no means an obviously good thing: The list of unwanted outcomes from the current proposal is so extensive that the benefits had better be so extraordinary and so absolutely certain in order to balance them all.
But perhaps there is no greater reason to not do it than that it simply won’t improve things for drivers.
Really? How can this be? As well the obvious problem with this project that it will add super capacity for a short stretch of the motorway network and therefore just shifts any bottleneck to the next constriction, particularly the extremely difficult to expand CMJ or Spaghetti Junction, there’s also a bigger structural problem with building more roads to fight traffic congestion. It can’t work. We all have experienced being stuck in traffic on a motorway and sat there wishing if only the authorities had just built an extra lane all would be sweet, well it would, wouldn’t it? However the evidence from all round the world shows that while that may help for a little while it never lasts, especially in a thriving city and especially if these extension starve the alternatives of funding, condemning ever more people to vehicle trips on our roads. Soon we’re stuck again wishing for another few billions worth of extra lanes all over again.
Here’s how it works; each new lane or route simply incentivises new vehicle journeys that weren’t made before; a well known phenomenon called induced demand. Road building is also traffic building, the more we invest in roads the more traffic and driving we get, and not just on the new road; everywhere. Traffic congestion is, of course, simply too much traffic, too much driving. Take for example the I-10 in Houston, the Katy Freeway. In that famously auto-dependent city they freely spent Federal money and local taxes disproportionately on just one way to try to beat traffic congestion, the supply side: ever more tarmac [Houstonians can boast the greatest spend per capita on freeways in the US]. The I-10 which began at six to eight lanes has just had its latest ‘upgrade’ to no fewer than 26 lanes! That ought to be more than enough in a flat city with multiple routes and only half the population Los Angeles. So what happened? According to recent analysis it has made driving this route significantly worse.
Traveling out I-10 is now 33% worse – almost 18 more minutes of your time – than it was before we spent $2.8 billion to subsidize land speculation and encourage more driving.
But hang on, those trips must need to be made, right, or people wouldn’t make them. Well in the absence of direct pricing it is hard to know exactly how valuable these new trips are. So first they really ought to price routes like the I-10 properly to reduce unnecessary journeys clogging up the valuable ones, like the truckies and trades [it is partially tolled now]. But the real problem in cities like Houston is the absence of any useful alternatives to driving [an earlier extension of I-10 took out an existing rail line!]. Providing those alternatives is how congestion is best dealt with. Not completely solved of course, that can only happen by collapse of the city economy like in Detroit, and no-one wants that solution. But traffic congestion can be made both manageable and, for many, no longer an issue, by providing them with attractive alternative options. And in turn this frees up the roads sufficiently for those who have to or prefer to drive. Especially when this is done in conjunction with direct price signals- road pricing; tolls or network or cordon charges.
Houston may be forever too far gone down this hopeless road but that doesn’t mean we have to follow it. Here is a description of the same problem in Sydney, with the solution:
Most people will take whichever transport option is fastest. They don’t care about the mode. If public transport is quicker they’ll catch a train or a bus, freeing up road space. If driving is quicker, they’ll jump in their car, adding to road congestion. In this way, public transport speeds determine road speeds. The upshot is that increasing public transport speeds is one of the best options available to governments and communities wanting to reduce road traffic congestion.
This is called the Nash Equilibrium [I would rather say better than faster; there are a number of variables including speed that inform our choices];
This relationship is one of the key mechanisms that make city systems tick. It is basic microeconomics, people shifting between two different options until there is no advantage in shifting and equilibrium is found. We can see this relationship in data sets that make comparisons between international cities. Cities with faster public transport speeds generally have faster road speeds.
Which brings us to the Waitemata Harbour. It currently has 13 general traffic lanes across two bridges, one walking and cycling lane on the upper harbour bridge, and some ferry services generally not competing with these crossings. The Harbour Bridge carries increasing numbers of buses from the hugely successful Northern Busway, the very success of which exactly proves the theory of the equilibrium described by Dr Ziebots above. In the morning peak the buses carry around 40% of the people without even a single dedicated lane on the bridge itself. And it is all the people using the busway that allow the traffic lanes to move at all. In fact NZTA argue that one of the main reasons for building a new crossing is the numbers and the size of the buses now using the current one.
The Upper Harbour Bridge is about become significantly busier because of the multiple billions being spent on the Waterview connection between SH20 and SH16, the widening of SH16, and the bigger interchange between SH81 and SH1 on the Shore. These huge motorway expansions will generate more traffic of course, but also will provide an alternative to driving across the lower Harbour Bridge.
What is missing anywhere between the North Shore and the city is a Rapid Transit alternative to these road lanes. Like Sydney always has had.
It is its [Sydney Harbour Bridge] multi-modality that makes it truly impressive, some 73% of the people entering Sydney on the Bridge from the Shore at this time are doing so on just one of the train lines and one bus lane; a fraction of the width of the whole structure. So not only does it shame our Harbour bridge aesthetically it completely kills it for efficiency too.
Auckland’s bridge was always only ever designed for road traffic, and should be left that way, the clear way forward is to add the missing Rapid Transit route as the next major additional crossing [after adding the SkyPath to the existing bridge].
In 1992 it [Sydney Harbour Bridge] was supplemented by a pair of two lane road tunnels that up the cross harbour tally for this mode to match the number coming over by train [bridge plus tunnels = 12 traffic lanes], but that wasn’t done until the population of the city had hit 3.7 million. The high capacity systems on the bridge saved the people of Sydney and Australia from spending huge sums on additional crossings and delayed the date they were deemed necessary by many decades. But anyway, because the additional crossing is just road lanes it only adds around 10% extra capacity to the bridge. To think that the government here and NZTA are seriously proposing to spend multiple billions in building a third Harbour Crossing in Auckland with the population only at 1.5m, but not only that but they are planning to build more capacity for the least efficient mode; more traffic lanes.
The good people at NZTA of course know this, but we just seem stuck in a bad habit of road building in a similar way as Houston is, because the money for motorway building comes from central government some people believe this makes it free, in a similar way that the highways in the US are largely funded by the Federal government, unlike public transport, which is more locally funded [Known as ‘path dependency’ and is well covered in the academic literature: Imran, Pearce 2014]. This means the pressure to evaluate the effectiveness of motorways over the alternatives is much weaker. Here is a slide from an NZTA presentation proudly proclaiming how much more traffic this massive project will generate:
Of course this growth can be met by a parallel Rapid Transit system instead. The success of the Busway here and the enormous uptake of the recently improved Rail Network show that Aucklanders are the same as city dwellers everywhere and will use good Transit systems when they get the chance. And two much smaller and therefore cheaper train tunnels have much greater capacity than the proposed six traffic tunnels. Twice as much in fact: the equivalent of twelve lanes and without adding a single car to city streets. Furthermore converting the Busway to a rail system, which is entirely possible, and depending on the system may even be quick and easy, means that buses can be completely removed from bridge freeing up more capacity there for general traffic; cars and trucks:
- Removing buses from the existing bridge would free up some capacity. 200 buses per peak hour ~= 1,000 cars ~= 60% capacity of a traffic lane. So a dedicated PT crossing provides car users with an extra lane (once you account for reverse direction). Not huge, but not negligible either.
- Mode shift: by providing a fast and more direct alternative route you will get mode shift, providing more space to the cars that remain. So you have more vehicle capacity and less demand = a real congestion benefit.
So compared to a new road tunnel where both crossings would need to be tolled, and simply generate more competing traffic for drivers through the whole city, the dedicated PT option would seem to be better even for motorists. The better, faster, and more attractive the Rapid Transit route the freer the driving route will remain; with more people choosing the car-free option: The higher the Transit utility; the higher the driving utility.
Of course while a rail crossing will be considerably cheaper to build than a road crossing it still needs a network either side of the harbour to make it useful. Are there good options for this? In fact there are a number of very good options, all with varying advantages and disadvantages that need serious investigation. And it is important to remember by the time this project is being built the public transit networks in Auckland will be considerably more mature. The City Rail Link will have transformed the newly electrified rail network to a central role in the city, it will quickly have doubled from 2015’s 15 million annual trips to 30 million and more. The New Bus Network will be functioning and with the new integrated zonal fare system meaning people will be used to transferring across routes and modes to speed through the city. The increase in bus numbers and population will make driving in the city less functional. There will certainly many tens of thousands more people in the city without their car, many with business or other reasons to travel across to the Shore. And importantly there will almost certainly be a new Light Rail system running from the central isthmus down Queen St and terminating downtown.
The quickest and cheapest to build will probably be to take the city Light Rail system through Wynyard Quarter and across the harbour, as outlined by Matt here. The busway can be most easily converted for this technology, as it is already designed for it. Furthermore being the only rail system that can run on streets it can also most easily include branches to Takapuna and even Milford to the east, and from Onewa up to Glenfield. This also has the advantage of balancing the existing city-side routes, unlocking a downtown terminus, not unlike the CRL does for the rail network.
What a North Shore light metro network map might look like.
Higher capacity and with the great advantage of cheaper to run driverless systems are is Light Metro like the massively successful SkyTrain in Vancouver. As described for Auckland here. However like extending our current rail system to the harbour it would require a more expensive city-side tunnel to Aotea Station for connection to city network. We know work has been done to prepare Aotea station for this possibility. Matt has also explored other variations here.
Perhaps the best answer for both the near term and the long term is to build tunnels that can take our new Light Rail vehicles for the years ahead but are also capable of being converted to the higher capacity Light Metro when the demand builds so much to justify the further investment of the city tunnel between Wynyard and Aotea Station. Bearing in mind the LR vehicles AT are planning for are high capacity [450pax ] and they can run in the cross harbour tunnels and the busway at very high frequencies. And that Light Metro systems can use track geometries much closer to LR than can conventional rail systems.
So in summary, the bane of the motorist and the commercial driver, traffic congestion, is best dealt with on the demand-side as well as the supply-side. We have spent 60 years just supplying more tarmac, and now it is time to get on with addressing the demand side: Building quality alternatives and providing clear incentives to fine-tune peoples choices.
And, just like road building, investing in quality Rapid Transit will grow the demand for more of it. It will also shift land use, incentivising agglomeration economies and greater intensification around transport nodes, as well as individual habits to suit this option more. What we feed, with infrastructure investment, grows. And vitally, inducing this sort of movement instead of driving is entirely consistent with other the demands of this century; especially our country’s new commitments to reduce our carbon emissions, and the use of our own abundant and renewably generated energy.
This project is both so expensive and potentially so valuable or so damaging that it needs a fully informed public debate about the possibilities. Gone are the days that NZTA can just keep building what its used to without real analysis of all alternatives, or that a politically expedient option sails by without serious evaluation. Because it can be transformed into a truly great asset for the city and the nation on this important route from the eye-wateringly expensive and clearly dubious idea from last century that it is now.
What’s clearly missing from this picture, especially once Light Rail fills ‘The Void’, and some form of rail goes to the airport?:
Body without a head: Official post CRL rail running pattern
I’ve left this a bit late; today is the last day to get your feedback in on some quick fixes coming to P Rd. But it doesn’t take a moment to choose between the two near identical options and just a few moments more throw a word or two it in as well. Go here.
In general AT and the Local Board are to be commended for the proposed changes as they will enable the street design to better follow the development of a new depth to the Ponsonby Rd strip; the noticeable lift in intensity throughout this area from Ponsonby Central and other places where the retail and hospitality now reaches further away from P Rd itself: Trading activity here is now much more 3-D and there are simply many more people.
Option 2. Fullsized PDFs here
What is at stake and why does this matter? Ponsonby Rd is one of Auckland’s many urban centres that all deserve the same kind of improvements, the same re-tilting back towards providing better amenity for people and granting less space and free-reign for vehicles. So everything I say here about Ponsonby Rd is also true for other areas, adapted to local conditions. Additionally Ponsonby Rd can act as a leader in this change, because it has that kind of role in our city, it is an early adopter kind of place; the forces driving change are evident here earlier and more powerfully than other areas.
The importance of this cannot be overstated. Small nudges can lead to big improvements; if only we could get our institutions to lead instead of follow on these issues, or at the very least be more responsive. In practice traffic engineering’s inbuilt methodology of ‘predict and provide’ with regard to anything other than vehicle traffic actually becomes; ‘lag and reluctantly catch-up’ and only when forced to. This has become an unhelpful conservativism that is a tremendous brake on placemaking by those controlling our streetscapes. I get the tradition of technical conservatism inherent in other branches of engineering, for example in structural engineering, but this is an unhelpful carry-over into street design, a field that ought to have input from both spatial designers and engineers, but without the later having a veto over final outcomes. A subtle shift in the pecking order around street design could unlock a great deal of potential in our city.
For example take the intersection of Ponsonby with Richmond and Picton [below]. This used to have a Barnes Dance crossing, like there still is at the top of Franklin Rd. It now has pedestrian movements concurrent with vehicle traffic movements complete with every variety of arrowed turning manoeuvres across pedestrian flows. Simple observation shows this to be overly complicated and delaying for the ever increasing numbers of pedestrians. A small group of locals approached AT through the local board about this and got the following response:
Certainly it doesn’t have consistently high pedestrian levels; it does gets quiet here around 3am, but it sure as hell has very high numbers for an intersection outside of the City Centre, and is surely busier than the Franklin intersection. The shot below was taken on a sunny Saturday in December so shows it at a peak, but similar levels are not unusual through the day. And the schools remark is double curious, first it is an odd criteria for what is primarily a shopping and hospitality area, but also it fails to spot that this intersection pretty much exactly triangulates Richmond Rd School, Auckland Girl’s Grammar, and Freemans Bay School; students for all three certainly travel through here. And note there is absolutely no claim that what we are requesting might be unsafe in AT’s view, we can only assume [it isn’t stated] that they are, as usual, privileging driver time over pedestrian time, assuming there may be additional delay for some drivers with a Barnes Dance? They can’t deny that there would be greater clarity for all users with a Barnes Dance.
Happily the writer also added this:
but then this:
More positively AT are now catching up with reality on the issue of the side streets off P Rd. We have long campaigned for raised pedestrian tables on these, and at last they look like they’re coming. Fantastic. The footpath on this long spine is the key public realm here and is appallingly fractured by continuos carriageway that gives all priority to the one or two occupants in any vehicle over the often multitudes on the pavements. Might is right, is what the current street design says to us all. We look forward to seeing this solution at the tops of all these lovely narrow Victorian lanes eventually. A consistent and clear communication to us all when driving that this is a people place first and foremost.
The other great opportunity is to continue the existing street-tree amenity along the length of the area. These are of inestimable value; living proof of the old urban design truism:
‘Whatever the question; the answer is almost always a street tree’
In particular a row of trees is proposed for the over-wide Mackelvie St. This is good, the street needs compressing and enlivening now that it has many more attractors further down it. It has a new laneway through to Richmond and is soon to get another through to Pollen St as well. However it is my view that trees should not be in the middle on the street as proposed but rather on the eastern side where there are already hospitality businesses with outdoor chairs and tables. This means that people could sit under them on the widened pavement and they wouldn’t constantly be being pruned by passing trucks. They would be able to be enjoyed physically as well as visually by people. The second raised table probably ought to move up to connect the two laneways too.
There’s plenty of width here to narrow the carriageway in order to draw pedestrians down into this newly activated zone of retail, hospo, and laneways. But the trees should, in my view be where the parked cars are on the left in the above picture, not in the middle of the street, moving the parking out to where the silver car is now. Those power lines could surely be undergrounded too.
Ponsonby Rd; A car-topia by design, yet an increasingly people rich place in spite of this.
Lastly this is a set of minor changes and it has to be mentioned that the issue of cyclelanes has been kicked down the road for later. The addition of new parking on Ponsonby Rd is not helpful for cyclists as this a street with a growing reputation for dooring incidents. The number of riders is increasing noticeably. There is a lot of additional parking coming to new buildings in the area and we feel this plan fails to take a sufficiently holistic view of the whole area and this new supply in particular into consideration. An issue for future action.
Below is what I added to my preference for Option 2:
Ponsonby Road Improvements
For both options:
First general context; as a local, who uses the street everyday with all modes, I am astounded by the rapid and sustained increase in activity everywhere in the area currently. Especially people on foot, but also on the road; driving and cycling, and stepping on and off the buses. I don’t believe that the physical environment is at all appropriate any more. The auto-domination of the entire width of P Rd is not helpful. A whole lot of additional parking is coming with Vinegar Lane which will further increase attempts to drive through what is increasingly a people rich environment. While 40kph limit is good the street design doesn’t support it.
The most important public realm here is the long fabric of footpath, it’s kind of like the biggest organ of the human body; the skin, an overlooked but vital resource. This needs improvement in duration, connection, and quality. So fixing the constant breaks at the side streets with raised tables is a vital and urgent upgrade. This will at last support the pedestrians’ right to the street for at least the length of the slim width they are currently allowed. Its virtual extension across the carriageway is also desperately needed. This is why we support the return of the Barnes Dance to Richmond/Picton.
Street trees offer so much all users, the gaps in their appearance on P Rd and side streets need filling at every opportunity, especially anywhere people might linger [everywhere]. Shade and beauty are glorious utility.
Mackelvie St is currently over-wide, and needs compression to be more attractive to users, to draw people down to the attractions away from P Rd, to the new laneways and other businesses. The narrowing of the carriageway is good, however I really think the new trees would be far better down the southern side of the street where the carparking currently is, instead of the middle of the street, as there are already cafe table on the pavement here, and the increased width and new shade would be fantastic for users of the hospitality businesses here. This seating faces north and is blistering for the times of the year there are leaves on the trees. And this would help these businesses, this may not be what the owners say, retailers seem to often be extraordinarily fearful of change, and to misunderstand what us customers are drawn to.
Right hand turning into and out of MacKelvie needs looking at in more depth, and may need restricting.
The second raised table in MacKelvie should align with the new laneways, ie needs to be higher up the street.
Cycling gets new parking but no where to ride but for us over-confident types; this will need to be addressed soon; the numbers are rising fast. Until then how about at least some sharrows on one lane each way on P Rd?
I am concerned that the increase in on-street parking on P Rd is a step backwards and will create problems later when more long term improvements are proposed. Quick fixes are great; but keep an eye on the longer term.
In summary: The raised tables are great, any increase in street trees is fantastic. Until proper bike lanes are added I think sharrows in the outside lanes on P Rd would go a small way towards legitimising the ever increasing cycling there…..all good for a quick fix, and I look forward to further improvements.
We’ve written before about the construction disruption coming to central Auckland next year. In particular there are two big half billion dollar full block rebuilds in the Convention Centre and the Downtown development and associated tower, plus the City Rail Link early works, then there are numerous other office and residential towers due to start. Only projects very close to the CRL route are shown below, there’s a lot more to the west both at Wynyard and around Sale St and elsewhere:
AT have some details on their CRL page about the details of their work, including a video of the Albert St process, no doubt they will communicate more closer to the time. Work on the pipe-jacking access shafts start early next month on Albert St. But as there is so much other construction starting next year I wonder if AT wouldn’t be wiser to really take an bold line on this as it all winds up? For the people who are used to driving through the city it’s more than likely these habits will be impacted. I feel the best way for AT to manage this frustration is to front-foot it, to ‘own’ this disruption, explain that people should not expect to get by without making changes. Say this is going to be big and difficult, but worth it in the long run. Just hoping to minimise disruption and try not to draw attention to it and that it’s all going to be ok seems to me to invite more of a backlash. In particular to invite accusations of carelessness and incompetence.
I think AT should consider a little Catastrophising; should call down a full ‘CARMAGEDDON’ for the central city next year. This has four potential benefits:
1. They can’t then be accused of downplaying or not taking the disruption to peoples’ commutes and daily business seriously.
2. It is likely to get a number of people to change their plans especially it may get more people to trying other methods for getting into the city, thereby actually helping to reduce the impacts of all this construction activity.
3. For these and other reasons it is likely that it won’t actually be as bad as they paint it, so people will feel more relief than anger.
4. It is a good way to get communication into the media, and with it the opportunity to discuss the value of the projects too.
Here’s an example of what I mean. The I-405 in LA:
A section of I-405 was closed over the weekend of Friday, July 15, 2011 as part of the Sepulveda Pass Improvements Project. Before the closing, local radio DJs and television newscasts referred to it as “Carmageddon” and “Carpocalypse”, parodying the notion of Armageddon and the Apocalypse, since it was anticipated that the closure would severely impact traffic.
In reality, traffic was lighter than normal across a wide area. California Department of Transportation reported that fewer vehicles used the roads than usual, and those who did travel by road arrived more quickly than on a normal weekend. The Metrolink commuter train system recorded its highest-ever weekend ridership since it began operating in 1991. Ridership was 50% higher than the same weekend in 2010, and 10% higher than the previous weekend ridership record, which occurred during the U2 360° Tour in June 2011. In response to jetBlue Airlines‘ offer of special flights between Bob Hope Airport in Burbank and Long Beach Airport, a distance of only 29 mi (47 km), for $4, a group of cyclists did the same journey in one and a half hours, compared to two and a half hours by plane (including a drive to the airport from West Hollywood 90 minutes in advance of the flight and travel time to the end destination). There was also some debate about whether the Los Angeles area could benefit from car-free weekends on a regular basis.
Granted this was only for one weekend, but still the principle is the same; own the cause of the likely negativity boldly.
What do you think is the best way for Auckland deal with these growing pains?
This is AT’s official future vision for the Rapid Transit Network in Auckland. I feel the need to show this again in the context of a number of uninformed views about the CRL popping up again, as one of the chief misunderstandings is to treat the City Rail Link as a single route outside of the network it serves.
All successful transport systems are designed through network thinking and not just as a bunch of individual routes, this is true of our existing and extensive motorway network just as it is true for our rapidly growing Rapid Transit one. The Waterview tunnel is not being built just so people can drive from Mt Roskill to Pt Chev, and nor is the CRL just to connect Mt Eden to downtown.
The CRL is but one project on the way to a whole city-wide network, as is clearly shown below, and as such it doesn’t do everything on its own.
But then having said that because it is at the heart of the current and future city-wide network it is the most crucial and valuable point of the whole system. That is true today and will continue to true for as long as there is a city on this Isthmus. In fact it is hard to overstate the value of the CRL as by through-routing the current rail system it is as if it gives Auckland a full 100km Metro system for the cost of a pair of 3.4km tunnels and a couple of stations. This is simply the best bargain going in infrastructure in probably any city of Auckland’s size anywhere in the world and is certainly the best value transport project of scale in New Zealand. Because it is transformational* for the city and complementary to all our existing systems, especially the near complete urban motorway network.
Additionally the capacity it adds to the region’s whole travel supply is immense: taking up to 48 trains an hour this can move the equivalent of 12 motorway lanes of car traffic. All without flattening any place nor need to park or circulate those vehicles on local roads and streets. And all powered by our own renewably generated electricity. This is how the city grows both in scale and quality without also growing traffic congestion.
This map will evolve over time as each addition is examined in detail. For example I expect the cost-effectiveness and efficiency a rail system over the harbour, up the busway and to Takapuna to become increasingly apparent well before this time period. In fact as the next harbour crossing, so we are likely to see that in the next decade, otherwise this is that pattern that both the physical and social geography of Auckland calls for. Additionally Light Rail on high quality right-of-ways, although not true Rapid Transit, will also likely be added in the near term.
Welcome to Auckland: City.
* = transformational because it substantially changes not only our movement options, the quality of accessibility between places throughout the city and without the use of a car, but also Auckland’s very idea of itself; we have not been a Metro city before: It is doing things differently.
Matt suggested adding this more recent version. I agree this is a good idea, it shows just how quickly ideas are changing in Auckland right now. This is a very fluid and exciting time for the city as the new possibilities are becoming acknowledged by all sorts of significant players. It remains my view that extending our existing rail system is better for Mangere and the Airport, but that taking AT’s proposed LR across the harbour in its own new crossing is a really good option:
And just this morning we get wind of these very big changes for those making plans for Auckland. It looks like the funding roadblocks [pun intended] for the necessary urban infrastructure that the growing and shifting Auckland needs may be melting away….?
The Sydney city centre is fantastic. It’s vibrant, varied, exciting:
And, like all successful cities, full of people. So how do they all get there? Of course some are there already, the City of Sydney has some 200,00 residents, but many journey in each day from the suburbs.
The streets are full of traffic, most are not like the part of Pitt St shown above, where pedestrians have priority:
The Bridge is full of traffic:
And there’s a couple of road only tunnels that were added next to the bridge, the Eastern Distributor, the Anzac Bridge, and many other roads in, so in just one of the AM peak hours 25,000 people drive into, or through, the Centre City on a weekday morning.
But that’s nothing. It’s only 14% of the total, just over twice the number that walk or cycle [source]:
80% arrive on Public Transport. Over 100,000 in that one hour on trains [2011/12]. Because they can.
They would have to, it would be spatially impossible to have such a vibrant city centre if any more than a small number accessed it by private car. There would no space for anything but roads and parking if they tried. No space for the city itself, nor for quiet places away from the hustle:
So while Sydney streets feel very busy with cars, and they certainly have priority to almost all of them, they aren’t actually as central to the the functioning of the city as they appear. There’s just is no way Sydney would be the successful, dynamic, and beautiful city it is without the investment in every other means of getting people to and through the city. Especially high capacity, spatially efficient, underground rail. And nor would the streets be able to function at all if more were forced to drive because of the absence of quality alternatives.
And more is coming too. Next month a second much bigger Light Rail project begins to add to the current one, and a new Metro line with new harbour tunnels is also underway. Driving numbers will likely stay steady into the future, but the city will only grow through the other systems. City streets are vital for delivery and emergency vehicles, but really successful city cities don’t clog them up with private cars to bring in the most essential urban component; people. That’s just not how cities work; even though that may be the impression given by the sight of bumper to bumper traffic on city streets.
And successful cities always appear congested; the footpaths are busy, the stations are crowded, and the traffic is full. Because they are alive and attractive for employment, commerce, entertainment, habitation; in short; urban life. This is the ‘seductive congestion’ of successful urban economies. To focus on reducing traffic congestion without sufficient investment in alternatives for people movement is to misunderstand what a city is and how they work. Sydney is not perfect, but it has a thriving and vibrant, properly urban centre built on properly urban movement infrastructure.
All else there stands on the quality of this investment.
Auckland Star April 1973. Back in the Dark Ages it was considered appropriate to near kill the patient in order to help them. In the 1970s Central government transport planners nearly succeeded in killing the Auckland City Centre through the subtle act of flattening its densest and most proximate dormitory suburbs, then cutting it off any still standing from the city, and turning city streets into motorway off ramps. The charm and glory of these multi-year campaigns are still with us today on the beautiful avenues of Hobson and Nelson Sts, the terrible road pattern and wasted landuse of Union and Cook St, and the blighted devalued areas of K Rd and Newton. And of course the violated and severing gullies themselves. The scale of this ‘surgery’ can be seen in this spread.
The accompanying text is fairly flat and informational.
It seems the desire for a Tabula Rasa, a blank slate, like those postwar planners had in Europe, was so great that we made our own ‘bombsite’.
Happily now we live in more enlightened times and the next city surgery of scale will be much more sophisticated, the City Rail link which as an incision compared to this earlier work is laparoscopic; minimal invasive surgery. No need to maim the patient. Once done no one will even see it, except for that high value resource of people flooding on to city streets not in a car looking for a parking space. And will supply at least as much capacity as the three motorways that meet at this point do today*. So the CRL will double the accessibility to the nation’s most concentrated, biggest, and highest value employment centre, and fastest growing residential area, seamlessly. After the recovery from a few precise cuts, that is.
*Show your work, as Peter always says:
CRL 24 trains per hour each way 750 per train [not crush load; that’s 1000] ~ 36k [crush 48k]
M’ways 12 lanes @2160 [1800 vehicles @1.2 occupants] per lane hour ~ 26k
Of course the buses on the Bridge land some 9000 souls currently too.
Last week the latest iteration of the National Land Transport Programme was announced. This is largely a business as usual plan, dominated by the big spend on a few massive state highways projects. However there are a few things to be celebrated, especially for cycling, and even more in the language and thinking in the supporting documents. This was repeated at the launch too, especially in the words of NZTA CEO and AT Board representative Geoff Dangerfield, and NZTA Auckland/Northland Regional Director Ernst Zöllner.
The high level aims are all strong and commendable. The focus on ‘economic growth and productivity, safety, and value for money’ are incontestably valuable. If they were to add ‘resilience, energy security, and environmental performance’ it would probably be a perfect list. But of course this is really set by the Government Policy Statement.
Dangerfield was his usual clear and persuasive self, setting a high level context and skilfully bating away questions. Zöllner was particularly articulate about both the dynamic nature of the situation in Auckland and the unformed quality of Auckland’s PT networks; especially the incomplete nature of the core Rapid Transit Network. Both noted the strong growth of PT ridership numbers, which will see a rise in the PT opex spend.
Here’s what the agency says about the Transit and Active modes, in the Providing Transport Choices document:
All incontestable good sense, and exactly the sort of points regular readers here would recognise, especially the emphasis on the value of the high quality own-right-of-way Congestion Free networks of rail and dedicated busways.
People using public transport on high-quality public transport services with a dedicated right of way, like the Auckland Northern Busway or metropolitan rail networks, can now enjoy fast, efficient journeys on comfortable modern buses and electric trains, while freeing up road space for other people and freight.
There remains, however, some considerable daylight between this analysis and the actual projects being funded. This is especially the case with the comparatively tiny sum of $176m for Public Transport Capital Works in Auckland out of a total $4.2 billion spend over the three year period in the region [~4%] and $13.9 billion nationally. This sum [half of which is from the Council’s Transport Levy] will bring much vital kit, like the Otahuhu, Manukau City, and Te Atatu bus interchanges. But is a long way from fixing those big gaps in the RTN network. In response to my questions on this they quite reasonably countered that some funding for bus capex is in other budgets, notably under the AMETI programme, as part of the North Western massive highway works, and the Northern Busway extensions.
However the two Busway sums do not result in the construction of even one metre of additional RTN. For the Northern Busway the previous minister deleted construction of the proposed extension from the accelerated motorway package [a loan to be met from future NLTF], so all we are left with is ‘future proofing’ and no one can ride on a busway that has only been future proofed for. On the Northwestern we do get the improvement of bus shoulder lanes and a station at Te Atatu; but no RTN. AMETI is the best of the bunch, but that’s only if the proposed BRT does happen instead of the place-ruining flyover that appeals more to some entitled voices there.
Then we come to the great problem that the National Land Transport Fund is barred from investing in rail infrastructure yet Auckland is now showing the huge value of using this separate network for moving increasing numbers of people completely outside of traffic congestion. And some RTN routes are clearly best served by rail. Just as well the Council has the courage to just get on with the CRL first stage by itself so at least this vital gap at the heart of the RTN is getting a start.
The case for near term investment in PT and especially for completing the RTN can be summarised thus:
- current demand growth of 20+% on Auckland’s Rapid Transit Network,
- the RTN is showing improved operating cost effectiveness as it grows,
- the strongly voiced value the agency sees in quality PT networks especially their positive effects on traffic congestion and economic growth,
- the well known relationship between what is invested in and what then grows in use plus the positive externalities of increased PT use,
- and the observed sub-optimal nature of the city’s current PT networks in both quality and extent, ie the clear opportunities for improvement.
So despite the good work being undertaken by many in all our transport agencies: NZTA, AT, and MoT, there seem to be structural problems that are leading to important opportunities
being missed in our only city of scale
. It is this context that I wrote to NZTA Auckland and Northland Director Ernst Zöllner with concerns about two specific projects that embody these issues. As this post is already quite long I will run the letter tomorrow morning in a follow-up post…
AT are doing some very very good things at the moment, they are showing leadership and courage to make rational but bold decisions. Like dropping the Reeves Rd fly-over in favour of a BRT solution, creatively investigating ways to bring modern light rail to over-crowded bus routes, and quickly rolling out long overdue bus lanes on arterials. These are all fantastic and are signs of a nimble and lively institution, one that is responding to a changing world with a changed response. One that is resisting the natural tendency of public agencies to just roll on doing the same as before and not risk trouble. I applaud this and the hard working and dedicated individuals who are carrying out.
But at the same time, at least at the time of writing, AT has lost its way on Great North Road. So why have they got it so wrong here?
Looking at that first list we can see what all these issues have in common; they are all discretely transport issues; as you’d expect this is AT’s core competency. BRT versus a traffic flyover in Pakuranga? This is a debate between competing transport projects, each can be costed and outcomes evaluated. Analysing whether more buses will be able to deal with the demand on Isthmus and City routes or whether a higher capacity technology may be needed? Again this is problem of spatial geometry, vehicle size, route speed, likely passenger volumes, boarding times, vehicle dimensions etc. All the kinds of things a transport organisation ought to excel in, and that AT increasingly shows it does.
But in examining the widening of Great North Road as if it only has transport outcomes they are showing the limits of this competency. That ‘place value’ just doesn’t compute is shown by the bewildering array of excuses being rolled out by AT to justify an act they clearly consider trivial: The removal of the six 80 year old Pohutukawa. First was an attempt to blame the need for killing these trees on improved cycling and public transport amenity in order to ‘bring long-term environmental benefits’:
We regret that the trees will be lost but a major benefit is that they will make way for cycle lanes to the motorway overbridge and for an extended bus lane and bus priority measures in Great North Road.
Making travel by cycle and bus more efficient and convenient is consistent with Auckland Transport’s drive to encourage the use of public transport. This will bring long-term environmental benefits as more people choose alternative modes of transport, to the car.
This is to draw an extraordinarily long bow. There are no ‘cycle lanes to the motorway overbridge’ in the proposed plan. There is absolutely no more cycling amenity on Great North Rd than there is currently, ie a wide footpath, except the new one will have no shade nor glory from the grand Pohutukawa. There is proposed to be a slightly longer but still intermittent bus lane. And as all this takes place as part of a massive increase in traffic lanes, including a double slip lane, to say that this project is designed to ‘bring long term environmental benefits as more people choose alternative modes of transport, to the car’ is frankly, an untruth.
That statement would be justified if fully separated cycle lanes and proper Rapid Transit was at the core of the project. They are not.
Both AT and NZTA spend public money and it is our legal and moral responsibility to deliver the most objective cost-efficient solutions to the ratepayers and taxpayers that planning and engineering can devise, for the least possible cost.
Absolutely right. Cost, and value, is exactly the issue here. We all certainly want our money spent wisely by our public servants. But there are obvious problems with this assertion, first the cost is only relevant in the context of the value; a cheap thing is a waste if it is not very good. And the people of Auckland see losing the trees as too high a cost for what they propose. That AT don’t see they value of the trees how and where they are, or so discount it so, is essentially the heart of the disagreement. We understand that they have a low transport value, but AT cannot ignore values outside of their core discipline, particularly place values, as their actions have huge effects on the quality of life and place that are not captured by driver time savings, traffic flow, or PT ridership numbers. Neither AT nor NZTA can just ignore these issues and simply hide within their speciality. And nor can they claim that a couple of new trees are the same as magnificent ones that have witnessed the last 80 years at this spot.
Additionally, there is no evidence that the preferred option is less expensive in direct financial cost than say Option Six, which the peer review
found to have no significantly different traffic outcomes. In fact Option Six must surely be cheaper to construct as it is one lane narrower and doesn’t involve removing the trees:
There are other issues that could be raised with this text like the bold claim the whole purpose of the Super City is to reduce congestion:
The founding premise of the Auckland super city was that the city’s congestion was costing $1 billion a year in lost productivity and this had to change.
Both this idea of the centrality of congestion busting to the whole purpose of the city and the quoting of a $1billion annual congestion cost figure show how blind AT have become to other issues of value. Other costs. Especially perhaps things that are hard to quantify. But then congestion cost itself is a very hard thing to quantify. The most recent attempt in New Zealand, published by NZTA itself [Wallis and Lupton 2013]
find that the figure for Auckland is more likely in the realm of $250 million.
But regardless of this supposed quantum it has long been understood that congestion is not solved by building more roads
, that in fact while temporarily easing one route, overall this only encourages more driving and auto-dependency for a place, and ultimately worse congestion everywhere. It is, quite literally, the loosening of the belt as a ‘cure’ for obesity. It is also understood that the best outcome for all road users, the best way to combat congestion, is to invest in the alternative Rapid Transit route, particularly where none currently exists:
This relationship is one of the key mechanisms that make city systems tick. It is basic microeconomics, people shifting between two different options until there is no advantage in shifting and equilibrium is found. We can see this relationship in data sets that make comparisons between international cities. Cities with faster public transport speeds generally have faster road speeds.
So again the heavy cost of this work, both financially and in the loss of the trees, a massive reduction in place value, is too high for this outcome.
As some levels of AT seem to admit they place no value on the trees, or indeed anything that isn’t directly transport related, the best outcome would be for the Board to give them direction to find a solution that both keeps the trees and meets reasonable near term traffic demand and in fact meaningfully incentivises the mode shift that AT correctly values:
Urban roads and state highways working together to keep the traffic flowing and fast, efficient road, rail and ferry passenger services that — together with walking and cycling — entice Aucklanders out of their cars.
-Auckland Transport Metro Magazine
This is an issue of cost, and value. The people of Auckland, Auckland Transport’s ultimate customers and employers, find the cost to place-value too high, and the value of the proposed outcome too low, to justify this action. The public may have been slow to realise what was planned here but have now made their views clear. Recently we have come to expect bold and innovative solutions from AT for all sorts of difficult problems. So it would be very unfortunate if the Board were to miss an opportunity to call a halt to this irreversible action and to seek a smarter solution.
And because work has begun the most efficient and cost effective solution is probably to make the small but significant change to Option Six, leaving the trees, adding the additional slip lane, but settling at least for now, for the two east bound lanes away from the motorway overbridge instead of three. It would be good to see the real effects are after the opening of the Waterview connection before rash actions are taken. If a third lane is deemed necessary here [even though only two lead into it] it is clear that could be added in a few years as MOTAT as planning to restructure their whole relationship with this corner. AT can save some cost and some grief now and revisit the issue with more information and without the pressure from a NZTA deadline. It could be that they find that an east facing buslane and separated cycle way is of higher value through here…?
