On Friday while we were basking in the glow of the opening of another great cycling project, the government were busy turning the sod of the next motorway widening project to get underway, something with decidedly less fanfare – to the point there hasn’t even been a press release about it. This was for the Lincoln Rd to Westgate section of SH16 with the most prominent thing I’ve seen being this tweet from Prime Minister John Key
The NZTA also published this video which includes Transport Minister Simon Bridges praising the project.
As mentioned, this $100 million project is widening SH16 between Lincoln Rd and Westgate includes: adding more motorway lanes, some bus lanes, a cycleway as well as upgrading the Royal Rd interchange. Some of the work was originally meant to have been done as part of that the over budget Lincoln Rd interchange project.
While there are a few useful things coming as part of the project, like all non-motorway features, they generally appear to be half arsed and incomplete. This includes:
- The cycleway will be a useful addition, mainly because it will be at a nicer grade than the local road alternatives. I currently ride through this area when going to/from work on the North Shore and the local network options drop below the motorway before rising up above it creating some very steep streets to navigate. But while the cycleway will be useful, the NZTA will force cyclists off at Royal Rd interchange, up a steep section of Makora Rd and through the intersection with Royal Rd. Given the grades, a simple underpass of the off-ramp seems like it should have been easy as well as presenting an easier grade for cyclists.
- Bus shoulder lanes are being added to the motorway. While this is definitely an improvement it’s not the dedicated NW Busway that we need and buses heading further west will be forced to merge out of the bus lane at the Royal Rd interchange. That means to get a proper busway in the future we’re going to have to go back and widen the motorway further, likely taking homes and probably rebuilding the cycleway again when it could have all be integrated at the same time. I recall that back when the NZTA were consenting Waterview and the causeway, they used the excuse that the former ARC plans didn’t list that section of SH16 as a rapid transit route as to why they weren’t including a busway. But those same plans did list Henderson to Constellation via the motorway as a future RTN route as one so it seems the NZTA pick and choose which of the plans it listens too.
There’s another feature of this project the NZTA have not said a single word about, that they’re taking 7547m² of land from a local reserve under the public works act plus another 1666m² as an easement for access, all of which is hidden under the brief bullet point above of Stormwater treatment. Information on the NZTA’s plans for Lowtherhurst Reserve are detailed in the agenda to the Henderson-Massey Local board at the beginning of April and the land they want for a stormwater pond is shown below in pink. The land in question is also what can be seen in the background of the video above.
The reserve is almost 44,000m² but most of that is steep and covered in bush. Only about 14,500m² is flat and grassed so the NZTA want to take half of that. I know somewhat well as I ride through it as part of my commute.
The NZTA offered the council/local board one of two options:
A. base option is financial compensation for the land only. Boundary fenced off from the reserve
B. the development and use of a wetland walkway and multi-activity use area for the local community with Auckland Council maintaining the footpath and multi-activity area at an ongoing cost of $500 a year (this will be cost neutral as there is a cost saving of $555 from reduced mowing on the reserve resulting from the divestment of land).
More detail on each of them is provided in the report but the minutes show the local board supported selling the land and chose option B. They’ve also requested the money received by the council for the sale of the land go to other open space priorities in the local board area.
According to the NZTA website, the project is due to be finished in February 2019.
On Friday Transport Minister Simon Bridges officially opened the Te Atatu and Lincoln Rd sections of the Western Ring Route.
Simon Bridges officially opening the two projects
The NZ Transport Agency says the official opening today of two upgrades to Auckland’s Northwestern Motorway kicks off a significant year in the city’s transport history.
The Lincoln Interchange and Te Atatu Interchange projects were officially opened by Transport Minister Simon Bridges at a ribbon cutting ceremony this morning.
They are the first of several improvement projects to be opened this year as part of the Government’s $2.4b Western Ring Route – designed to keep Auckland moving.
Both of these projects are crucial building blocks in the Western Ring Route, providing an additional route to State Highway 1 and the Harbour Bridge and changing the way people move around Auckland.
NZ Transport Agency Highways Manager Brett Gliddon says the improvements at Lincoln and Te Atatu are part of a series of projects being completed during the next year to ensure the Northwestern motorway is able to handle the growing demands from everyone who uses it – drivers, people using public transport and those who walk and cycle.
“Increasing the motorway from two to three lanes in each direction on this stretch of the motorway will help traffic to flow better leading to greater travel time reliability, and an efficient alternative route to use instead of State Highway 1,” says Mr Gliddon.
I was apparently invited to the opening but the NZTA sent the email to the wrong address – not that I would’ve been able to attend due to work commitments.
Regardless of what mode you use, for many out west the completion would be a welcome change as works and the disruption that came with it have been an ongoing challenge. But I wonder just how successful the project has been, especially the Lincoln Rd section. Here’s are some of the quick facts from the NZTA’s press release.
The $145million upgrade of the Lincoln Interchange has widened and realigned the onramps and motorway exits to improve safety and traffic flow. There are new dedicated, purpose built bus lanes providing a greater level of service than before. The Northwestern Cycleway has also been extended and improved.
The $65million Te Atatu Interchange project has added an extra lane in each direction between Te Atatu and Lincoln Roads, new motorway on and off-ramps as well as raising and widening the Te Atatu overbridge.
Work will begin later this year on the Lincoln to Westgate project to tie into this just completed work at the Lincoln Road Interchange. It will include widening the Northwestern motorway to three lanes, improved on and off ramps, creating bus lanes and extending the Northwestern Cycleway.
So let’s take a quick look back to when these two projects each began.
Lincoln Rd Interchange
The project started all the way back at the end of October 2010 and has seen the interchange vastly supersized, for example the bridge over the motorway was widened from two lanes to seven. At the start of the project the NZTA laid out these basic facts. The important ones for this post being that it would cost $100 million, be completed in 2013, include all four ramps and extend the cycleway as far as Huruhuru Road.
Immediately you can see a few glaring issues, these being that the project is $45 million over budget and three years late. To be fair, I understand the timeframe was deliberately delayed so that funding could be diverted to help deal with the immediate aftermath of the Canterbury earthquakes, three years late? I can also accept the idea that they slowed construction so it could better be tied into the progress of the rest of the Western Ring Route. Not much point adding lanes and capacity only for it to hid the queue not far down the road. As infomercials love to say “but wait, there’s more”.
As I mentioned the works were to include all four ramps and extending the cycleway to Huruhuru Rd – via a torturous four leg crossing of Lincoln Rd, no underpass here. Here’s a map of the interchange design. I’ve rotated it to better compare with the following image.
Here’s what it looks like as of the beginning of April.
You can see very clearly that the westbound onramp and the extension of the cycleway past Lincoln Rd are completely missing. That’s because they’ve been moved in with the project widening the section of motorway from here to Westgate – another ~$100 million project.
So all up it appears we’ve got a project that is $45 million over budget, three years late and they still haven’t even completed some of the work they said they would do.
Te Atatu Interchange
Thankfully the Te Atatu interchange doesn’t appear to have the delays that the Lincoln interchange suffered, but it does appear to have had its own cost blowout. This is from the press release when the project got under way.
Key features of the $50m project include widening the Northwestern motorway between the Te Atatu Road and Patiki Road interchanges, widening all five ramps on the interchange, enhancing existing facilities for walkers and cyclists and widening and raising the Te Atatu Road overbridge.
Work will start on the improvements at Te Atatu in the new year and is set to be completed in 2016.
Here’s the Te Atatu interchange from April
So the project was completed in 2016 like they said it would be but was $15 million over budget.
The Te Atatu project includes the fantastic cycleway underpass
So all up we’ve got projects over budget, late and missing components. Perhaps not quite the NZTAs finest hour. Imagine what kind of amazing local cycling network that extra $60 million could have delivered if spent within the area.
It’s quite likely that within the next decade we’ll be seeing the heavy machinery out in these sections once again, this time adding the piece of the puzzle that was absurdly left out of this project, the Northwest Busway.
If you live in the North West and were looking forward to the end of what has now been over five years of constant road works along the Northwestern Motorway – which started with Lincoln Rd back in October 2010 – then don’t get your hopes up for the disruption ending any time soon. The NZTA are now starting to once again talking about the section they’ve so far missed in their grand widening schemes – the bit between Lincoln Rd and Westgate. What’s more despite being silent on the project for so long they’re now talking about starting the $100+ million widening project in little over six months with work expected to take till 2019 to complete.
The NZTA say the project involves
- Widening the motorway to create 3 lanes in both directions for motorists
- Creating bus shoulder lanes next to the motorway in both directions
- Extending the Northwestern Cycleway to create a 3-metre wide shared walking and cycling path from Lincoln Road to Westgate
- Improving the Royal Road interchange and ramps. Replacing, raising and widening Royal Road Bridge, creating an on-road cycle lane, shared walking and cycling path, and new footpath
- Replacing and raising Huruhuru Road Bridge
- Extending the Lincoln Road on-ramp heading westbound and replacing one side of the bridge over Huruhuru Creek
- New landscaping, urban design and lighting features
- New wetlands to treat stormwater run-off
- Improved safety barriers and new noise walls.
I’m not necessarily opposed to the project as there are some useful aspects to it but it does seem to have the typical motorway building approach to it – that being to widen everything around this section thereby increasing the justification for to spend a heap of money ‘fixing’ on the newly created bottleneck.
Probably the most useful aspect of the project for me personally and one I’m very keen to see built is the cycleway. Normally cycleways alongside motorways aren’t great however in this situation the motorway has a shallower grade than the surrounding streets do so will be a welcome addition. That brings me to my first issue/concern. The map above shows the cycleway veering off with the motorway ramps to Makora Rd which is steep and quite narrow. As Royal Rd is on a ridgeline it means that diversion adds additional height for those on bikes (or walking) to deal with. I’d prefer to see the cycleway pass under the offramp and then stick to the level of the motorway – obviously with a connection to Royal Rd. The diversion also adds at least two sets of traffic lights that need to be negotiated.
An issue perhaps even more important is the situation for buses. The NZTA are only building bus shoulder lanes in the project. While bus shoulder lanes are better than nothing it ignores that Auckland Transport want a full busway built on this section – although AT acknowledged in the West Auckland New Network consultation that bus shoulder lanes would go in first.
What it all means is that AT will still have to build a busway separately at some point in the future at a much larger cost rather than the NZTA taking the One Network approach they love to talk about these days. It also highlights another inconsistency the NZTA run with. You may recall in the debate before the current works were started we and others called for a busway along SH16. At the time the NZTA hid behind the then Auckland Regional Council’s Regional Land Transport Strategy (RLTS) which only suggested bus lanes alongside the motorway. That’s not the same situation with this section though as the route from Lincoln Rd to Westgate and beyond were included as part of a possible future Rapid Transit route between Henderson and Constellation Drive.
One aspect I am a little surprised about is that the NZTA are only going to upgrade the interchange as it is and that they’re not going to add north facing ramps.
As part of this now rapidly approaching project the NZTA are going to hold a few open days – note: these aren’t consultation, more just “here’s what we’re building”.
Come along to one of our open days where you can learn more about the project and talk to the project team.
When: Saturday 14 November, 10am – 2pm
Tuesday 17 November, 4pm – 7pm
Where: Royal Road School Hall, 112 Royal Road, Massey
They say that in time for the open days, this day next they’ll update their website with designs and more information about the project.
Lastly while actual construction doesn’t start till next year the timeline the NZTA have put out suggests we’ll start seeing some physical works soon such as removing houses in the way of the widening.
This image came up the other day on the NZTA’s Facebook page and it highlights just how much wider SH16 will be between Te Atatu Rd (top) and Lincoln Rd when the works have finished. Before they started work the motorway was just two lanes wide each way. When finished it will be four lanes wide comprising of three general traffic lanes and a bus shoulder lane each way.
The stages of construction are shown in this diagram below
The corridor could get even wider as the North West busway is planned to be on the south side of the motorway
In the third in my series of posts wrapping up the year I will look at what’s happened with roads this year.
Roads of National Significance
The RoNS have continued as they did last year with one notable exception.
Western Ring Route
The Western Ring Route works are in full flight now as will be evidenced to anyone who drives along SH16 with roadworks in place from east of Western Springs all the way through Northwest of Lincoln Rd from 5 separate projects.
- St Lukes Interchange
- Waterview Connection
- Causeway upgrade
- Te Atatu Interchange
- Lincoln Rd Interchange
The TBM working on the Waterview connection has broken through with the first tunnel and in December made a start on the second one. At the same time the most visible part of the project has been the large yellow gantry has been building towering ramps that will connect the tunnels to SH16 in each direction.
Over the next year we should finally see the Lincoln Rd section completed and I imagine significant progress on the other projects – although they are still a few years from completion.
Puhoi to Wellsford
In 2014 the NZTA were issued with consent to build the Puhoi to Warkworth motorway – a road even the NZTA’s analysis says is only really busy during holiday periods. Amazingly we’re still yet to see any real economic analysis for the project which is likely because it’s terrible based on the work we saw before the government named it a priority. The government of course continue to claim it’s all about the economic development of Northland despite the existing toll road – which saved more time than this motorway will – not making any difference.
Over 2015 we’re likely to see the NZTA working towards a PPP to get this project built however it’s not likely we’ll see any construction start.
Basin Reserve Flyover
Perhaps the biggest surprise of 2014 was the Board of Inquiry declining the NZTA’s application to build a flyover around the edge of the Basin Reserve. In the end the commissioners hearing the case concluded the impact on the local community from having a massive flyover was just too much after it was able to be shown that most of the benefits the NZTA claimed the road would provide were actually attributable to other projects. The decision was embarrassing for the NZTA and the government seeing as it was using the governments new fast track process which means the decision can only be appealed on points of law – which the NZTA are doing.
I’m not aware if a date has yet been set for the appeal but it is likely to be later next year.
Also in Wellington, the first transport PPP was signed in July for the construction and operation of Transmission Gully, another project with a horrific business case. Initial works should have started by now however won’t really ramp up till next year. The PPP will see the NZTA paying $125 million a year for 25 years once the project has been completed. Unlike many PPPs that failed overseas, for the consortium building the road there is little risk as all the demand risk sits with the NZTA, in other words we pay providing the road is open – and if it is damaged from a something like an earthquake we have to pay at least some of the costs of that too.
The other RoNS projects in the Waikato, Bay of Plenty and Christchurch have continued along. I’m not sure of the progress of all of them however the Tauranga Eastern Link is meant to be completed in 2015.
Auckland Motorway Projects
In 2013 the government announced a series of additional motorway projects for Auckland. The widening of the Northern Motorway between Upper Harbour and Greville Dr has just been completed and in November started consultation on ideas for further changes to that section including a motorway to motorway interchange between SH1 and SH18. Some of the ideas are absolutely massive in scale such as concept 3.
Of the other projects, works to grade separate Kirkbride Rd moved ahead and earlier this month the NZTA announced the contract had been signed with construction starting in January
We haven’t heard much about the other accelerated project which will see the southern motorway from Manukau to Papakura widened but I would expect we will do in 2015.
In addition to the accelerated projects the NZTA has now made a start on widening SH1 Northbound between Ellerslie-Panmure Highway and Greenlane – a project that’s been on the cards for a while and for which the Ellerslie Station platform was narrowed a few years ago to accommodate.
Accelerated Regional Roads
In addition to the RoNS, and to shore up their support from some rural communities, this year the government announced a spend up of over $200 million on a number of regional state highway projects that can’t get funding due to it being sucked up by the RoNS. The Funding for these projects is coming from the proceeds of asset sales the government has undertaken. Some of the projects appear to be of low value however not all are.
Auckland Transport started the year with the opening of the new Panmure station and in November they opened Te Horeta Rd which is the new road running alongside the rail line and Panmure station from Mt Wellington Highway to Morrin Rd.
In October both AT and the NZTA launched consultation on ideas for the East West Link after calling off a proposal for a motorway through Mangere right at the beginning of the year. They haven’t announced the results yet but I’m fairly certain either option C or D has been picked as the option they are proceeding with.
In November AT announced they have come up with a route for the Mill Rd corridor and will be working towards securing a designation for it. The most disappointing aspect for me about the project – other than some of the case for it has likely been destroyed by the fast tracking of the SH1 widening – is that even with a brand new corridor, AT are still designing a crap outcome with features like unprotected cycle lanes or shared paths and pedestrian/cycle unfriendly roundabouts.
We’re still driving less
One positive trend I have started to notice is our transport institutions are starting to take notice of is that we’re driving less. In the last few months in particular it’s started to be mentioned in publications such as the Briefing to the Incoming Minister and in research papers.
What have I missed?
The motorway lanes at St Lukes have been parted as part of the project to widen the St Lukes Rd bridge.
In many other cities when you see the motorway parted like this it would be for a busway or rail line to be installed. Wouldn’t it be fantastic if this work was for the creation of a Northwest busway (Admittedly it probably isn’t quite wide enough).
Below are a couple of examples of median running transit.
Pretty much anyone who has driven along State Highway 16 in recent times would have noticed the massive amount of construction going on with almost half of the entire motorway affected by works. Once the St Lukes interchange upgrade gets under way soon then I believe every single trip along the motorway will be affected by works in some way.
The works are made up of a number of separate individual projects that all form part of the Western Ring Route. They include the St Lukes Interchange, the Waterview Connection, the causeway upgrade, the Te Atatu Interchange upgrade and the Lincoln Rd interchange. Most of these have only really visibly got under way over the last year or so however the last of those, the $100 million Lincoln Rd Interchange is has been going on for some time, starting in late 2010. That’s about 3½ years ago.
There has definitely been progress and we now have a massively oversized interchange that has been completed (I don’t have any photos sorry but you should really see the westbound off-ramp which is up to four lanes wide). As a side note, I understand one of the reasons the interchange is so big is that the former Waitakere City Council weren’t clear on their land use planning for Lincoln Rd (which is a disaster) so the interchange was basically designed to be as big as possible to cater for potentially massive growth. While most of the interchange itself has been completed, the work seems to be primarily focused on widening the motorway either side of it including the Henderson Creek and Huruhuru Creek bridges. Once those have been completed the motorway on either side will be three lanes each way plus there will be bus shoulder lanes.
Overall the NZTA say the project isn’t due to be completed until 2015 but here’s the thing, that’s quite different to what was said when they started the project. Back in 2010 they said in a FAQ with the press release.
Q: How long will it take?
A: Construction will begin imminently and will be completed by 2013.
So that suggests the project is running two years late. For what was meant to be approximately a three year project that’s quite a long time. That would also make the interchange project an almost 5 year ordeal and one of our longest motorway construction projects in history. So here is some information on just how long other massive projects have taken in recent times.
|Central Motorway Junction upgrade
||4 years 2 months
|SH20 Mt Roskill Exenstion
||3 years 9 months
|SH20 Manukau Harbour Bridge duplication
||2 years 4 months
|SH20-1 extension to Manukau
||4 years 7 months
||4 years 3 months
|Upper Harbour Bridge Duplication
||3 years 10 months
||2 years 10 months
|Victoria Park Tunnel
||2 years 4 months
||3 years 9 months
There are some very challenging projects on this list.
Now there could be some legitimate reason why it’s taking longer. Perhaps the NZTA deliberately decided to slow down the project so that it wasn’t completed so far in advance of projects like the Te Atatu interchange that it caused its own problems i.e. widening the motorway to three lanes could have been done but until the Te Atatu interchange is completed those three lanes would have just had to merge down to two anyway. Still there are some potentially good reasons for them to have finished earlier, in this case the extra lanes created could have been used as bus lanes in the interim helping to make up for delays caused by the closure of bus lanes elsewhere on the route.
The NZTA have awarded the contract for the “upgrading” of the St Lukes interchange and the widening of the motorway between there and Waterview. Here’s the press release:
The contract to construct the next stage of Auckland’s Western Ring Route – upgrading the Northwestern Motorway (State Highway 16) between the St Lukes Road and Great North Road interchanges – has been awarded to the Australian-based infrastructure company, Leighton Contractors.
The $70m project is jointly funded by the NZ Transport Agency and Auckland Transport.
A two kilometre-long section of the motorway will be widened from three to four lanes in each direction. There will also be improvements to the motorway ramps and the St Lukes Road -Great North Road intersection, while the St Lukes Road overbridge spanning the motorway will be widened to benefit drivers, walkers and cyclists.
The Transport Agency’s Highways Manager, Tommy Parker, says this is the last of six projects to connect the Northwestern and Southwestern (SH20) motorways.
“The upgrade is part of our programme to get our network ready for the increased volume of traffic when the Waterview tunnels connecting the Northwestern and Southwestern (SH20) motorways are completed in early 2017,” Mr Parker says.
Work is due to start in mid-autumn and be completed by late 2016. The other projects to connect the two motorways are the upgrade of the Maioro Street interchanges (SH20) which is completed, and the upgrade of the Lincoln and Te Atatu interchanges, the Causeway Upgrade Project, and the Waterview Connection, which are all under construction.
“Leightons bring plenty of infrastructure experience to the St Lukes project. The company is part of the Causeway alliance, and has been involved in some of our biggest Auckland developments including the Northern Gateway Toll Road and the Newmarket Viaduct Replacement Project.” Mr Parker says.
The Western Ring Route is a Road of National Significance, and will provide a 47km-long alternative to SH1 between Albany and Manukau. It will improve safety and city and regional transport connections for people and freight.
The project isn’t exactly a surprise as it’s been talked about for a while and was part of the overall Waterview consenting process that occurred a few years ago. In saying that it does once again bring into the limelight the claim often made (including in the last paragraph) that the Western Ring Route is about creating another route through the region when in fact this piece of work is all about making it easier to get from the airport to the CBD. This is even mentioned in the description on the project page.
The Waterview Connection project is one of the most important infrastructure developments ever to take place in New Zealand. Completing a motorway ring route around the city, it will unlock Auckland’s potential to become a truly world class city, combatting regional congestion and creating a direct, time-saving link between the International Airport and CBD.
The part of the project that is of most interest is the widening of the motorway bridge and the sections of Gt North Rd on either side. This is especially the case as the NZTA and Auckland Transport were at one stage looking to wipe out the large mature Pohutakawa trees that line the road so they could create one additional lane all in the aim of appeasing the gods of traffic flow. This is the before and after of what they showed to the local board a few months ago and which the board weren’t happy with.
The images below suggest they may have backed down on that though. As for what’s now going to be built, the NZTA say that the project includes:
- 3 lanes on the St Lukes overbridge in both directions
- Improved walking and cycling facilities across the bridge – you’ll be able to use both sides of the widened bridge
- Realignment the Northwestern Cycleway
Being able to use both sides of the bridge will be good but that seems to be the only thing.
Here’s what it will look like from above and facing south (click to enlarge)
Immediately there are a couple of major issues I see and they primarily relate to the intersection with Gt North Rd. Amazingly the NZTA and Auckland Transport are actually going to remove some of the few bits of existing pedestrian priority that currently exist. A person wanting to get from the eastern side of St Lukes Rd (where the carpark is) to MOTAT or Western Springs first has to battle their way across to the traffic island if they can find a gap in traffic thanks to the removal of the existing zebra crossing. Then instead of a simple trip across to the northern side of Gt North Rd they have to cross to the eastern side of St Lukes Rd and wait again to get across Gt North Rd.
It’s pretty clear that the primary focus of this project is about making it easier to drive at the expense of other modes. The extra lanes on the bridge are an attempt to squeeze a few more cars through the area. On westbound off-ramp there is also an additional queuing lane which will only serve to funnel extra volumes off the motorways and onto the local streets. It seems to be the typical ‘give every type of movement its own lane’ type approach that only ends up making life easier for cars. By in large everything seems very much the same business as usual crap we’ve seen for decades throughout Auckland.
The work to widen the North Western motorway is becoming ever more prominent – and soon requiring the closure of the bus lanes. So I thought I would look for some old photos from when it was under construction to help show how much the area has changed in the just over 60 years since it was built.
Back in 1949 Auckland was a very different place. For a start there were no motorways and we had trams rolling around most of the isthmus which was where most of urban development was focused. The land on the Avondale and Te Atatu Peninsulas was used for farming and of course the North Western motorway didn’t exist. One of the key reasons for building the motorway was apparently to provide better access to the airport – which at the time was at Whenuapai. This was also to be the main route north out of Auckland and it was only after the harbour bridge opened that plans to run the main highway north cutting through the central city emerged.

By late 1951 construction would be well under-way. In the two images below you can see the causeway extending out into the harbour.

By late 1955 you can see the Te Atatu Rd interchange starting to emerge.

On the city side, the motorway ended at Pt Chevalier where it joined Gt North Rd. It wasn’t extended to the city till the 1970’s when the CMJ was built.

Since opening the motorway has been widened and added to numerous times. It started out as a four lane motorway and by the time the current upgrade is finished, some parts will be up to 11 lanes wide when you include the bus lanes.
