In the May budget the Government announced they would fastrack yet another $800 million of motorway projects, partially financed by a $375 million loan. These were projects that had been identified in the Prime Minister’s Auckland speech in 2013. There were 3 main projects as outlined below.
Two of these projects have major potential to impact on 2 key elements of the Congestion Free Network.
The first is the State Highway 20A upgrade, which involves extending the motorway about 2 extra kilometres towards the airport.
Grade separation of SH20A and Kirkbride Rd intersection
Upgrading of SH20A to motorway standards: two lanes in each direction plus dedicated bus priority lanes
Reprioritisation of Ascot Rd / Kirkbride Rd intersection
Installation of truck priority lanes and ramp signalling
Relocation and integration of cycle lanes in local road network
Note there is no mention at all of rail to the airport, which would follow the motorway corridor from Onehunga most of the way to the airport. It is of upmost importance that a rail corridor is reserved by NZTA when they are planning and building the project. They have done this on the SH20 extensions through Mt Roskill, however there was a designation already in place so the situation is somewhat different. Auckland Transport has been investigating rapid transit along this route since 2011. Initially they said the route protection was to begin in late 2011, however 3 years later we have learned little. The latest we have is an April 2014 update which suggests that a preferred alignment will be identified in 2014. While the Airport’s Masterplan may be causing issues at the southern end of the route, work should still be moving ahead in the northern area. It is essential that NZTA and AT work together to speed up alignment identification in this area, something which has been highlighted by the Campaign for Better Transport. If the upgrade is built without an alignment for the rail corridor it will add huge extra cost to the airport rail project. For one thing all the new overbridges would have to be rebuilt, which would be a huge waste of money. Auckland Council need to send a strong message to the government that this would be unacceptable, and ensure the rail corridor is allowed for in the design.
The second project is the suite of Northern Corridor projects, which largely revolve around the State Highway 1 to State Highway 18 grade-separation and associated widening. In December 2013 NZTA claimed there were 5 main components to the Northern Corridor projects.
Component 1 is already under construction (costing $19.5 million). Component 2 seems to be the smart low-cost improvements. The announcement above seems to refer to Components 1 to 4, totally leaving out the much needed Northern Busway extension to Albany. Currently the Northern Express speeds the 15km from Britomart to Constellation Station in just over 20 minutes. However the last 4km to Albany can take 15 minutes as there is no bus priority. This busway extension is another project that NZTA and AT have been working on for years, and seems have got bogged down somehow. In 2011 NZTA were saying that the route needed to be designated soon due to the development taking place. Last year we found out a little more about the route investigations, which suggested it would cost $249 million.
The planned motorway interchange upgrade is quoted as costing an astonishing $450 million. For that cost the project is totally unnecessary for something that just replaces a few at grade intersections with ramps. The focus should be much more on cost-effective targeted upgrades, then we could have the busway extension to Albany and plenty of spare change. The result would be lots more people using the busway, and reduced traffic congestion along the entire Northern Motorway and CBD.
The third set of projects around the Southern Motorway don’t have any components of the Congestion Free Network linked with them. However the upgrades should be a good chance to make Great South Road better for pedestrians, cyclists and buses. The one positive of this project is this means the current expensive plans to turn Mill Road into a 4 lane highway should disappear, and be replaced by a much cheaper safety upgrade. This would be a great way to free up over $200 million to help with Auckland Transport’s stretched budget.
