Northern Corridor Improvements

Connecting Auckland’s motorway infrastructure and building for tomorrow.

The Northern Corridor Improvements (NCI) project connects Auckland motorway system as never before. A new direct motorway-to-motorway connection on the North Shore will mean commuters and freight can travel to and from Auckland Airport, West Auckland, Manukau and Hamilton far more easily.

The new link will connect SH1 directly with Upper Harbour Highway (SH18), opening up access to the new Western Ring Route (SH16).

With new shared pathways, everyone benefits; cars, freight, pedestrians, and cyclists, making the Auckland motorway network more user-friendly and little more robust now and for tomorrow.
