S. H. 1 – Auckland Motorway System

The Northern Busway is a segregated busway that runs along the eastern side of the Northern Motorway, part of State Highway 1, in the north of Auckland, New Zealand, linking the North Shore with the northern end of the Auckland Harbour Bridge. As of May 2022, the busway consists of two-way lanes running between Albany Station and Akoranga Station, and from Akoranga Station a southbound-only lane that joins the Harbour Bridge approaches just south of the Onewa Road on-ramp system. The busway previously ended at Constellation before an extension to Albany was constructed in 2022. Six stations provide access points for passengers to board; some stations have park and ride parking spaces; others have drop off and pick up zones only. City-bound Northern Express (NX1 and NX2) services commence from Hibiscus Coast Station or Albany Station; from Albany, the lanes reduced travel time to Waitematā station from around one hour by car during peak hours to about half an hour by bus. In the reverse direction, NX1 and NX2 services leaving the city travel north to the Akoranga off-ramp, cross over the motorway, and enter Akoranga Station, from where they travel north on the busway lanes. The busway lanes are also an important transport link within the North Shore, where they are the spine of the bus-based public transport system.
