This is Part 3 of our series wrapping up the year and in this post I’m looking at Roads. You can also see:
Here’s my summary
The Auckland Transport Alignment Project (ATAP) has been a huge feature of the year and while not strictly road related, I’ll include it in this summary. Importantly, despite I think asking many of the wrong questions and focusing too much on the modelling, it largely came out with the right answers. For example, it highlights
- We can’t build out of way of congestion
- A major expansion of the “strategic public transport network” is required
- Auckland’s motorway network is basically now finished (and also that scope for further widening seems quite limited)
- The Additional Waitemata Harbour Crossing really isn’t needed for a long time
- We need to move to a comprehensive, better pricing system – which ATAP calls “smarter transport pricing”. It suggests it could take a decade to work though the details before it became a reality.
Below is the proposed strategic road network for the next 30 years. As you can see most of this is already in place now.
Waterview/Western Ring Route
Near the end of 2015 the tunnelling was completed at Waterview over the course of 2016 the work has focused on fitting those tunnels out and completing all of the other aspects of the project, including the ventilation buildings and mitigation projects.
In September we revealed the NZTA had some new traffic modelling predicting the opening of the new connection to create havoc and that they were planning to emergency widen a number of surrounding motorways and local roads in a desperate bid to stop the shiny new centrepiece of their system from getting congested.
The tunnels are due to open in April, which is later than I thought it would be but I also wonder if that’s related to getting the emergency widening completed first.
In May the NZTA officially opened rebuilt Lincoln Rd and Te Atatu Rd interchanges as part of the wider Western Ring Route (WRR) project. Both were over budget and Lincoln Rd was three years later than originally stated (and that was even after moving one leg of the interchange to another project). In October the NZTA also celebrated the completion of the St Lukes interchange, with the Pohutukawa still intact.
In July work started on the next stage of the WRR, to widen the motorway between Lincoln Rd and Westgate. A section of motorway that might need to be rebuilt again in just a few years to add a north-western busway – something the government agreed (through ATAP) that was needed within a decade. We have heard rumours though that the NZTA engineers are changing their designs for the Royal Rd and Huhuhuru Rd bridges to accommodate a busway after they were told they might be responsible for delivering it.
Related to the WRR, just a few weeks ago the NZTA applied for consent for the Northern Corridor which will turn the section of SH18 east of Albany Hwy into a full motorway and provide a direct connection to SH1 (northbound). Importantly it also includes the extension of the Northern Busway. That process will be concluded in 2017 and previous indications from the NZTA suggested construction would start in 2018.
The East-West Link loomed larger in 2016 as the project marched on, culminating in the NZTA applying for consent a few weeks ago, at the same time as the Northern Corridor. The NZTA is almost certainly going to face a much bigger fight to get this project over the line though as it also faces significant community opposition, especially to plans to effectively cut off the port area with a motorway and swallow large packets of land for various roads
In June we revealed documents from the NZTA showing the cost had ballooned from $600 million to potentially over $1.8 billion, more expensive than the Waterview Tunnels ($1.4b). Yet from what we can tell the economic assessment is still based on earlier cost estimates. The documents also revealed some of main risks identified for the consenting of the project, with designs at the time putting the roads completely on newly reclaimed land.
Some of those risks have been mitigated a bit over the year as the latest plans place the road mostly back on current land with most of the reclamation planned to be for more extensive mitigation.
Puhoi to Warkworth
While on the topic of big State Highway Projects, the NZTA announced in November they had awarded the contract for the Puhoi to Warkworth motorway. Presumably construction will start in 2017 and is expected to be completed in 2022.
Auckland Transport consents for Mega Projects
Auckland Transport got consent for two of it’s mega road projects, both expected to cost north of $300 million.
They’ve also applied for consent for the Lincoln Rd upgrade which could cost more than $100 million.
Surprisingly little has been heard about AMETI this year. AT were meant to be applying for consent for the Busway between Panmure and Pakuranga but nothing has been made public yet.
In November the government announced a new speed limit guide which when in place would allow for some specific roads to have a 110km/h speed limit but also make it easier for local authorities to have lower speed limits in urban areas which would be welcome.
And despite the talk of safety, the road toll continues to defy the trends of the last few decades, increasing again over the last few years, as the graph below shows (to the end of October)
Are there any key changes I’ve missed?
Tomorrow’s wrap up will focus mainly on non transport stuff.
