Next steps

The Transport Agency, in consultation with Waimakariri District Council has been investigating ways to improve SH1 in the Woodend area to allow for future growth.

Investigations show that a four-lane bypass is the best option. A designation to protect the land needed for the new road has been confirmed in the Waimakariri District Council Plan.

At this stage the bypass is not expected to open to traffic before 2027.


Traffic volumes along State Highway 1 in North Canterbury and through Woodend are expected to double over the next 30 years. This traffic increase will come from a rise in long distance traffic such as freight vehicles and residential developments.

To cope with this growth the capacity on SH1 will need to be increased. If we plan for this now and protect the extra land needed for the bypass it will make things easier in the future.

The Transport Agency is committed to working with the Waimakariri District Council and the community to integrate this project with other community plans.


The new four-lane bypass will link in with the current motorway at Lineside Road and run through to the entrance to Pegasus on SH1.

The project will:

  • improve capacity and efficiency of traffic travelling through the Woodend corridor
  • improve the road safety, accessibility and liveability of Woodend for residents
  • improve access and connectivity for residents and businesses in Woodend, Pegasus, Kaiapoi and other local communities.
