We’re proposing changes to Cranford Street and the surrounding roads to coincide with the completion of the Christchurch Northern Corridor. We’d like to hear your thoughts on how to make this work for commuters and local communities.

Below are links to the feedback received, attachments received, and a feedback summary.


Next steps

  • Submissions will be heard by the Papanui-Innes Community Board on Monday 6 August 2018.
  • After this meeting, the Independent Traffic Expert will make his recommendation by way of a draft Downstream Effects Traffic Mitigation Plan, which will outline remedial steps required (if any) to avoid, remedy or mitigate the adverse traffic effects. This draft plan will be reported through the Community Board to Council.
  • Council will then be engaging with any potentially affected owners and occupiers of the streets identified by the Independent Traffic Expert in the draft Mitigation Plan. 
  • The recommendations set out in the final Mitigation Plan will then be reported through the Community Board to Council.
  • Council will develop the details and programme for delivery of the transport projects identified in the Mitigation Plan.  These projects will be individually reported through the Community Board to the Council for approval. 

Why we need to make changes

We’re expecting a significant increase in people travelling on Cranford Street when the Christchurch Northern Corridor(external link) opens in 2020. The Christchurch Northern Corridor will improve travel times to and from the north of the city. It will decrease the number of people driving in some areas such as Main North Road and increase the number of people using parts of Cranford Street.

We need to make some changes to Cranford Street and the surrounding streets to improve the travel times for people travelling through and minimise people taking short cuts through side streets which could affect local residents.

Why are we consulting?

The Christchurch Northern Corridor will extend the Northern Motorway through to QEII Drive and Cranford Street. You can find out more about the project at nzta.govt.nz/cnc.

This project finishes at the intersection of Cranford Street and Innes Road. A downstream effects management plan for Cranford Street and the surrounding area south of Innes Road will be prepared to manage the impact of the additional people and vehicles travelling through.

The plan will look to improve connections to help commuters to get where they need to go while maintaining the sense of community for businesses and residents in the area. This consultation will help to inform that plan.

Further consultation on each individual project from tha plan will happen before it is implemented.

Where is the traffic coming from?

We have done some investigations on the traffic impact on the area south of Innes Road. Even without the Christchurch Northern Corridor there will be increased traffic through the area due to population growth.

The drawing below shows how the Christchurch Northern Corridor will take some traffic from Main North Road and Marshlands Road. Main North Road is the major bus route to and from the north of the city and reduced traffic will allow for better bus priority. Reduced commuter traffic on Marshlands Road will allow for additional residential traffic as the area is developed.

The shared path that runs alongside the Christchurch Northern Corridor will connect into the Papanui Parallel cycleway providing a continuous cycle route.

What is the traffic impact?

Investigations we have done show that local streets will be affected in the morning and evening peak periods if no road improvements are made. The impact will vary street by street but a number of streets will have a traffic increase of over 30 percent.

The most affected area is shown in the image below.

We have considered a number of options and found that the best option both for traffic flow and to minimise short cuts through local streets is a combination of main road improvements and some measures to reduce speed in quieter streets.
