There will be additional traffic in the St Albans, Edgeware and Mairehau areas when the Christchurch Northern Corridor opens. We're starting transport projects to manage this traffic and improve connections in the area.
Receive updates on traffic mitigation projects
The Christchurch Northern Corridor (CNC) is due to open in December 2020 and will help people to travel to and from the north of Christchurch by extending the Northern Motorway from QEII Drive and Cranford Street, through to Innes Road.
Further information about this project is available on the NZ Transport Agency website(external link).
Construction of transport projects
Construction is now underway with work currently focused on Cranford Street and Sherborne Street, as well as the intersection of Warrington Street and Barbadoes Street. As part of the work we are installing a new water main between Berwick Street and Bealey Avenue. Thanks for your patience while we do this disruptive work.
We will begin consultation on traffic calming for specific streets in the next couple of weeks. We will be starting with people living near McFaddens, Weston and Knowles streets, where they intersect with Cranford Street. This will be followed by engagement with people on other affected roads including Mersey Street, Severn Street, Thames Street, Nancy Avenue, Kensington Avenue, Flockton Street and Francis Avenue.
We are working with our partner organisations to mitigate the expected increase in traffic on Cranford Street and other streets in a way that:
- keeps everyone safe
- encourages walking, cycling and use of public transport
- keeps people moving through the area
Councillors have prioritised the first part of this plan, which needs to happen before the Christchurch Northern Corridor opens. They also instructed staff to investigate several other projects that are important to the community.
Read more about the decision on Newsline.
Consultation on the projects took place in July and August 2019 and more than 50 changes have been made in response to feedback.
This consultation followed two previous rounds in mid-2018 and early 2019. The key themes of the previous rounds of consultation were:
- People, not cars
- Retaining a sense of community
- Safety, particularly for people walking, biking and accessing local schools
What else is happening?
We are working with our partners NZ Transport Agency, Waimakariri District Council and Environment Canterbury (ECan), on a package of projects that sit alongside the Christchurch Northern Corridor. The projects include park-and-ride facilities, additional bus services and a high occupancy vehicle lane.
High occupancy vehicle lane
The NZ Transport Agency will install a lane for vehicles with more than one person in them on State Highway One and the new Christchurch Northern Corridor motorway to encourage carpooling. This lane ends just before the Cranford Street roundabout. We are investigating whether this could extend along Cranford Street.
The Waimakariri District Council and NZ Transport Agency have agreed to co-fund park-and-ride facilities in the district and are currently investigating suitable locations. We are also investigating a park-and-ride facility near QEII Drive.
ECan has agreed to consider express bus services from Christchurch north that would travel along the Christchurch Northern Corridor and Cranford Street. We are assessing the impact of bus lanes along Cranford Street and Sherborne Street that would complement an express bus services.
Pricing strategies to manage future traffic demand
Pricing strategies work best when applied across a road network and not just to a single road corridor. We are exploring different methods that could be used to implement congestion charges across the city.
Environmental monitoring is starting to establish baseline data for air quality and noise and vibration that can be compared to data collected after the Christchurch Northern Corridor opens.
