Christchurch to Ashburton Expressway

 

National will build the Christchurch to Ashburton expressway, delivering approximately 60km of expressway between the Christchurch Southern Motorway and Ashburton.

The project will see the existing four-lane expressway extended from the Christchurch Southern Motorway through to Ashburton and will include new bridges over the Selwyn,
Rakaia, and Ashburton rivers.

The Canterbury region is New Zealand’s largest by land area and second largest by population. Strong, resilient and reliable transport networks are needed to continue supporting growth in the region.

The State Highway 1 route between Christchurch and Ashburton is a critical gateway for the rest of the South Island and complements the previous work by National to deliver the Christchurch Northern and Southern motorways, the rebuild of SH1 to Kaikoura and the newly promised extension of the Northern Motorway between Pegasus and Belfast.

Recognising the high volumes of traffic and potential for future growth in the region, National's vision for the SH1 link between Christchurch and Ashburton will deliver a highly engineered and safe road that provides reliable journey times to support the economic growth of the region and access to key markets.
