The Christchurch Northern Corridor (CNC) affects an area that extends from the Waimakariri River Bridge on the Northern Motorway to Cranford St and affects an area as far as Main North Rd in the west and Marshland Rd in the east.
The project involves putting three lanes on the Waimakariri River Bridge, constructing and extending the four lanes of the Northern Motorway to Cranford St, upgrading Cranford St and putting four lanes on part of QEII Dr. This project is being managed by the CNC Alliance, a collaboration of the NZ Transport Agency and Christchurch City Council.
This project, along with other scheduled works in the area, which include the Highfield subdivision development, Transport Agency safety improvements, KiwiRail maintenance and other city council improvements will cause a number of changes to roads in the area over the next two years (until 2020).
The below information is aimed at keeping the public aware of the latest transport impacts in the area to help them plan their travel.

As part of the Christchurch Northern Corridor (CNC) project, QEII Drive will be four-laned
between Main North Road and Innes Road. The two new lanes will be completed just before
Christmas. In the New Year the upgrade of the two existing lanes will begin and traffic,
between the QEII Drive bridge (east of Grimseys Road) and Hills Road, will be moved over onto the new lanes.
The traffic swap-over is scheduled to happen on Tuesday evening, 8 January 2019.
The Philpotts Road intersection with QEII Drive will need to be closed for around four weeks from Tuesday evening 8 January till 1 February 2019. This is to allow for the construction of temporary roads at Winters Road and Philpotts Road to connect to the new traffic lanes on QEII Drive. After the temporary access road from Philpotts Road to QEII Drive is in place, you can only access QEII Drive with a left out of Philpotts Road.
There will be no access into Philpotts Road from the new lanes on QEII Drive during the construction of the upgrade. There will no longer be a right turn out of Philpotts Road onto QEII Drive. The final lay out for this
intersection in 2020 is left in and out only. There will be a 60km/h speed limit in place on QEII Drive between Innes Road and Main North Road during the construction. Detour. When the Philpotts Road intersection is closed, you
can either use Innes Road or Main North Road as a diversion to get to QEII Drive.
