There will be additional traffic in the St Albans, Edgeware and Mairehau areas when the Christchurch Northern Corridor opens. We're planning how we manage this traffic and reduce the number of vehicles travelling along the route.

The Christchurch Northern Corridor (CNC) will help people to travel to and from the north of Christchurch.

The CNC extends the Northern Motorway to connect QEII Drive and Cranford Street, through to Innes Road. Further information about this project is available on the NZ Transport Agency website(external link).

To help manage the additional traffic when the CNC opens, an independent traffic expert has prepared a draft Downstream Effects Management Plan [PDF, 14 MB].

You can read an overview of the full plan at Have Your Say(external link). Consultation has finished, and community boards will make a recommendation on Wednesday 22 May.

The draft plan was informed by public engagement with the community in 2018 and seeks to balance the needs of local communities with safety and accessibility considerations, while ensuring an accessible city for all Christchurch residents, businesses and visitors.

The draft plan recommends changes to the arterial and local road networks.

Some of the other recommendations in the draft Plan include encouraging ridesharing, the use of public transport and active transport. These require work to happen outside of the area considered by the plan.

The Christchurch Northern Corridor and the Downstream Effects Management Plan are also part of a wider package of transport projects to improve travel to and from northern Christchurch.

Other projects include the Main North Road bus priority (still to be constructed), Western Belfast bypass, Papanui cycleway and Northern Line cycleway (still to be constructed).
