Phased tunnels for second Harbour crossing
Two new three lane road tunnels under the Waitemata Harbour, one going in each direction, and a separate light rail tunnel that will link to the existing Auckland Light Rail corridor is the proposed plan for a second Auckland harbour crossing, Prime Minister Chris Hipkins and Transport Minister David Parker announced.
The twin road tunnels would not be contingent on the light rail tunnels, with phasing options for the road tunnels to be considered by Waka Kotahi NZ Transport Agency, including whether to build both tunnels at once or separately. In either case, additional busway, driving and cycling and walking capacity will be created at each stage.
Separately, a future light rail tunnel is proposed from the Wynyard Quarter, under the harbour east of the Auckland Harbour Bridge, and on to six new stations on the North Shore. This too would be phased. Construction would not be expected to begin until after at least the first of the two road tunnels is completed.
“This is a bold plan for Auckland’s future that delivers a modern transport network that will connect all parts of the city,” Chris Hipkins said.
