Auckland Northern Corridor Improvements


This project will provide better links for Northern Motorway (SH1) travellers in Auckland and improve transport options on the North Shore for freight, cars, pedestrians and cyclists. It includes a new motorway connection between SH1 and SH18, opening up access to the Western Ring Route and airport.




To help facilitate interregional travel between Auckland and Northland by allowing the full benefits of the Western Ring Route to be realised by upgrading the SH18/1 connection.



  • Provide a new, continuous motorway route from the North Shore to and from the Western Ring Route and beyond, as an alternative to travelling on SH1 through the central city
  • Better link the people of the North Shore to their new neighbours in growth areas in the North-West
  • Separate local traffic and high speed motorway-through traffic along Upper Harbour Highway (SH18), easing congestion; creating better links; reducing harm to local communities; and supporting future freight and economic growth
  • Improve access in and out and around Albany
  • Create new reliable, safe services for bus users, walkers and cyclists
  • Widen SH1 in both directions for those travellers who stay on SH1 through the central city.
