• Northern Arterial Motorway

    Christchurch Northern Corridor Project – NZTA

Expected opening date from NZTA is Dec 2020

The Christchurch Northern Corridor (CNC) will extend the Northern Motorway through to QEII Drive and Cranford Street and includes a new four-lane motorway starting just south of the Waimakariri River and then continue to link with Cranford Street with off-road pedestrian and cycle facilities linking to existing and new cycle facilities in the area. It will be built to high modern safety standards and will also move heavy traffic off suburban roads making them safer, encouraging walking, cycling and the use of public transport – especially through Redwood and Belfast.

This new motorway is critical to supporting the continued growth of Christchurch as a business centre and the export hub for the South Island’s economy, and to improving journey times for commuters. Many of these commuters have rebuilt their homes in North Canterbury following the earthquakes.

BELFAST ROAD

Belfast Road will pass over the motorway and ramps will provide access to the Christchurch Northern Corridor (SH 74) – to and from the south. This will provide enhanced access in and out of the CBD.

LYTTELTON PORT

The Christchurch Northern Corridor (SH 74) will provide access between Belfast and the port via the QEII Drive and Anzac Drive route.

  • APPROX 11.5km

    The motorway is about 11.5km long from the Waimakariri River to Cranford Street.

  • PEDESTRIAN ACCESS

    Improved walking and cycling facilities.

  • REDUCES TRAVEL TIME

    When the new motorway is opened it will also reduce commuter travel time, and is expected to ease traffic to Main North Road by as much as 50%.

  • IMPROVE SAFETY

    By reducing congestion and increasing the flow of traffic, we will achieve safer outcomes.

  • SUPPORT GROWTH

    The facility will support economic growth and job creation.
