Auckland Rapid Transit Network

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….?

Waterview breakthrough

Congratulations to the NZTA and the team building the Waterview connection after Alice the tunnel boring machine broke through for the second tunnel this morning. There is still a lot of work to do to finish the tunnels such as digging the cross passages and building the actual roads but it is an important milestone. Regardless of your views of the project it is an impressive bit of engineering, especially just how accurate they are able to be.

Alice, the giant Tunnel Boring Machine (TBM) has today successfully completed excavation of the second motorway tunnel on Auckland’s Waterview Connection motorway project.

One of the largest TBM’s ever used in the Southern Hemisphere broke through into daylight after its 2.4km-long journey underground between the suburbs of Waterview and Owairaka.

“Today’s breakthrough is a massive milestone for a project that will transform the way Aucklanders get around their city – a brilliant and remarkable effort and a proud day that needs to be celebrated,” says the NZ Transport Agency’s Highways Manager in Auckland, Brett Gliddon.

Around 800 staff and contractors who’ve been working hard to deliver the project, stopped work this morning to watch the breakthrough together, live on specially erected screens and celebrate their success so far.

“The risks associated with constructing tunnels twice as long as the Auckland Harbour Bridge were always high and the Waterview team rightly needs to be congratulated for its engineering skills and innovation to complete this job safely and on time. That’s a fantastic achievement.”

The $1.4bn Waterview Connection is New Zealand’s largest ever roading project. It includes construction of twin 3-lane tunnels – the longest road tunnels in the country – and a giant interchange to connect Auckland’s Northwestern and Southwestern Motorways (State Highways 16 and 20).

The project is being delivered for the Transport Agency by the Well-Connected Alliance.

Tunnelling at Waterview first began in 2013. The first tunnel was completed in September 2014. In a rare manoeuvre for any TBM worldwide, Alice was then turned 180 degrees to complete her second drive.

“The project’s careful and detailed design, planning and operation for the construction of the tunnels and the complex turnaround grabbed some pretty amazing headlines in New Zealand and overseas,” Mr Gliddon says.

During her time underground, Alice excavated enough dirt to fill 320 Olympic-sized swimming pools and installed more than 24,000 concrete segments to line both tunnels.

The TBM’s job is now complete. Over the coming months Alice will be taken apart and returned to the German company, Herrenknecht, that designed and built her.

“Although it’s the end of the road for Alice she will leave behind a lasting legacy – the world class tunnels she helped construct that will benefit Auckland and New Zealand for 100 years and more,” Mr Gliddon says.

Meanwhile, there is a busy programme of work to complete both tunnels. Sixteen cross passages linking the two tunnels are being constructed, equipment to safely operate the tunnels together with lighting and signage are being fitted, walls and the ceiling are being painted, and back-filling continues before the motorway asphalt is laid.

The Transport Agency plans to open the tunnels and the adjacent Great North Road Interchange in early 2017.

The Waterview Connection completes Auckland’s Western Ring Route, a 48km alternative route to SH1. It will link Manukau, Auckland, Waitakere and the North Shore, improving network resilience, travel time reliability and bus shoulder lanes as well as upgrading cycleway and pedestrian facilities.

The Waterview Connection project is being delivered by the Well-Connected Alliance which includes the Transport Agency, Fletcher Construction, McConnell Dowell, Parsons Brinckerhoff, Beca Infrastructure, Tonkin & Taylor and Japanese construction company Obayashi Corporation. Sub-alliance partners are Auckland-based Wilson Tunnelling and Spanish tunnel controls specialists SICE.

I am looking forward to the project being finished for a number of reasons – not least of which is the project effectively marks the practical completion of the Auckland motorway network. The idea of “completing the motorway network” is one that has been around for a long time and work on the motorways came at the expense of all other modes for many decades. With Waterview completed I hope we can then start focusing even more on completing our majorly incomplete networks such as our rapid transit and cycle networks.

Of course focusing so much on the motorways was never meant to be the plan. Those that originally dreamt up the motorways also came up with a region wide rapid transit network and even saying it should be built first otherwise the city would end up congested. Unfortunately it seems that part of the report was filed at the back of a drawer somewhere and forgotten, the motorways progressed and congestion ensued.

The latest few images and videos from the Waterview Connection Project.

And the East Tamaki pre-cast facility which has now finished producing 24,000 segments and it plus the machinery are now up for sale. It highlights just what a massive logistical challenge these big projects are and something that will need to be repeated for the CRL.

This image also shows the progress of the southern ventilation building while the image after it shows what it should eventually look like.

I hope AT are planning to do something similar time-lapse videos for when they start the CRL works

Waterview Connection April Time-lapse and Fly-through

There have been two new videos from the Waterview Connection project in recent days. One is the regular monthly time lapse update the project have been producing and this edition shows them building two temporary bridges from the two tunnels to the northern approach trench so they can move tunnel lining segments and other equipment into the second tunnel easier. It also shows more of the construction of the ventilation building going in at the southern end.

The second and far more impressive video is one that has been shared around quite a bit in recent days and shows a drone fly-through of the entire project including all the way through the tunnel. It really highlights just how long and large the tunnel is.


Of course the project was also hit this week by news that it received a faulty batch of concrete and will require remedial work – although it sounds like the processes that the project set up were instrumental in detecting the issue which also affected a number of other projects.
