The Auckland Northern Corridor project (also known as the Northern Corridor Improvements (NCI) project) will provide a connection from the North Shore to and from the Western Ring Route, as an alternative to travelling on SH1 through the central city. The project includes:

  • a new motorway link between the Northern Motorway (SH1) and the Upper Harbour Highway (SH18) including the upgrade of SH18 to full motorway standard between the Albany Highway interchange to SH1
  • new lanes on the Northern Motorway between SH18 and Greville Road
  • an extension of the existing Northern Busway from Constellation Bus Station further north to Albany Bus Station, and
  • a range of local road, cycling and amenity commitments. 

Once completed, the dedicated busway will operate through to Albany Bus Station.
