Northern Corridor moving ahead

Auckland has no shortage of big road projects on the go at the moment but one of them that has at least improved a bit over the last few years has been the Northern Corridor Improvements project. This plans to convert the last remaining part of SH18 to full motorway standard with some direct motorway to motorway ramps to the north along with extra lanes. The improvement has come in the form of the NZTA now confirming that an extension of the Northern Busway will be part of the project. This a significant change as it had been specifically excluded by the government when the project was accelerated by the government in 2013 – which we understand was against the advice of the NZTA at the time.

The NZTA say the next stage of the project has now been approved which means they’ll be working towards getting consents before starting construction in 2018. As part of this they’ve now come out with an “Approved Draft Plan” which they say includes:

  • A new direct motorway to motorway connection between SH18 and SH1, separating motorway traffic from local road traffic.
  • Additional motorway lanes in both directions on the Northern Motorway (SH1) between Greville Road and Constellation Drive.
  • Extension of the Northern Busway from Constellation Bus Station to Albany Bus Station. Auckland Transport is investigating a new bus station along the extension in the Rosedale area.
  • A 5km dedicated shared walking and cycling path on the eastern side of the Northern Motorway (SH1), built alongside the new Busway extension and alongside Upper Harbour Highway (SH18) all the way to Albany Highway. A proposed new walking and cycling bridge across SH1 in Albany will connect Pinehill and East Coast Bays residents with Albany’s shopping, employment and university areas.
  • Local road improvements through the Constellation Drive and Caribbean Drive intersections, and a new Paul Matthews Road bridge.
  • Further investigation of a proposed bridge over SH18 to improve connections for the Unsworth Heights community

 

Here is the latest plan which also includes a few changes from the last time we saw the project almost a year ago. The main changes I can see compared to then are:

  • They’ve now clarified the connections around Paul Matthews Rd
  • They’ve dropped a big swooping on-ramp providing a direct connection from Albany Expressway to the motorway southbound.
  • Previously buses would use the bridge at McClymonts Rd to access the busway station before looping back to the motorway via Oteha Valley Rd. Now a new busway bridge will be built directly across the motorway to the station.
  • They’ve dropped a potential walking and cycling underpass from SH18 and seem to plan to include a connection as part of a new bridge extending Unsworth Dr
  • Previously there was a ‘potential path still under investigation’ showing along SH18 including west of Albany Highway. They’ve confirmed the walking and cycling path as far as Albany Highway but not west of there. This is a shame as the motorway has a much nicer grade than using Upper Harbour Highway

On the busway they say in more detail

It’s now confirmed that the project will include an extension of the popular Northern Busway from Constellation Bus Station to Albany Bus Station. This means buses will be able to travel on a dedicated busway all the way to Albany, reducing travel times and improving public transport options. Auckland Transport is also investigating a new bus station and Park & Ride options in Rosedale along the new busway extension. As part of this, Auckland Transport will look at local road improvements and additional feeder services that could help transport people in and out of the station from the East Coast Bays, North Harbour, and Rosedale. Similar to Smales Farm, it is expected that this station will be a destination station for the many people who work, go to schools or attend sporting activities in the area. It will also provide another station to catch the Northern Express service to and from the city

As part of this final step before going to consenting they are giving people another chance to have a say on the project. Unfortunately, this post is too late for any of the open days but you can still email them or fill in their survey which is focused on a few specific issues like urban design, the new busway station, walking and cycling options and some other local road changes like the potential Unsworth Rd Bridge.

I’d like to see is the busway built first as it would have an added benefit of giving people options during the inevitable disruption that will occur during the construction of the motorway.

One aspect that the NZTA hasn’t talked about since the project was announced is the cost. Back then it was estimated at $450 million but that was without the busway.
