Two lanes of traffic are now traveling on both the Halswell Junction Road and Springs Road bridges. Traffic continues to switch between the new lanes on Main South Road (SH1) to accommodate construction work and work on the road underneath the Robinsons Road Overpass is about to start.

Project details

The NZ Transport Agency is working to provide better access to and from the south of Christchurch, the city centre and Lyttelton, by improving the capacity, safety and alignment of the Christchurch Southern Corridor.

Traffic congestion will only worsen in this area over the next few decades, due to growth in the south and southwest, if significant improvements to road capacity are not made. For this reason the Transport Agency is upgrading the Southern Corridor into the city. The first part of this project, The Christchurch Southern Motorway Stage 1 was completed in December 2012.

The Christchurch Southern Motorway Stage 2 (CSM2) is made up of a new section of four-lane median separated motorway, from Halswell Junction Road to SH1 near Robinsons Road and an upgrade of the existing Main South Road (SH1), from north of Robinsons Road to near Rolleston, to four lanes.

While planning these projects, we have listened to input from local communities and stakeholders to ensure the highway meets the needs of its communities. We have also worked with the Christchurch City Council, Selwyn District Council and Environment Canterbury to ensure our plans complement the whole south Christchurch and Canterbury road network and that the network provides transport options for all road users (drivers, pedestrian and cyclists).
