The New Zealand Government has asked NZ Transport Agency to consider and provide advice on a Long Tunnel option for State Highway 1 (SH1) through Wellington city.

State Highway 1 (SH1) through Wellington City is heavily congested at peak times and while planning continues on the duplicate Mt Victoria Tunnel and Basin Reserve project, the Government has also asked NZ Transport Agency (NZTA) to consider and provide advice on a Long Tunnel option, Transport Minister Simeon Brown says.

“Boosting economic growth and productivity is a key part of the Government’s plan to rebuild the economy. The Long Tunnel option aligns strongly with priorities in the Government Policy Statement on Land Transport (GPS), including a reduction in travel times, greater resilience for the SH1 corridor, and improved safety for road users, pedestrians, and cyclists,” says New Zealand Transport Minister Simeon Brown.

“The Long Tunnel option has the potential to deliver up to 15-minute travel time savings between the region and Wellington airport, compared to around 2-3 minutes for the current parallel or diagonal tunnel proposals at Mt Victoria and the Basin,” says New Zealand Transport Minister Simeon Brown.

“The option would also see better urban amenity through greater reallocation of surface level road space to active modes and public transport in the CBD and greater opportunities for housing intensification. Enhanced regional connectivity to the airport and hospital would also be achieved with reduced city and state highway congestion,” says New Zealand Transport Minister Simeon Brown.

“The option would also mean less construction disruption for local traffic as the Long Tunnel option could be built with less disruption to the city centre and less impact on public and private properties required for other options.

“To rebuild our economy and ensure people and freight can get to where they need to go quickly and safely, we need to move at pace to deliver the infrastructure our country needs,” says New Zealand Transport Minister Simeon Brown.

“I look forward to receiving advice from NZTA on the technical feasibility, cost, and funding and financing options for this proposal as NZTA works on delivering the Government’s priority of a second Mt Victoria Tunnel in Wellington,” says New Zealand Transport Minister Simeon Brown.
