SH1 North Canterbury Corridor

About the project

• Saltwater Creek to Cam River, including Woodend, road safety improvements

  The 11.4km stretch of SH1 between Saltwater Creek and the Cam River is assessed as a high-risk section of highway, with high traffic volumes and speeds combining in some areas.

  Five people were killed and 30 seriously injured in the 75 recorded crashes on this stretch of road between 2011 and 2020*.

  Too many of these deaths and serious injuries were caused by head-on crashes. 

  While we can’t remove every hazard, we can put in place effective measures that will make SH1 in North Canterbury safer for everyone who uses the road.

  These include wide centrelines, flexible median safety barriers, and improvements at intersections such as traffic lights, roundabouts or left-in/left-out access to the highway.

• Safer speeds

  To ensure our transport system protects and helps us get to the places and people important to us, we’re delivering an Interim State Highway Speed Management Plan. Locations in North Canterbury include the Pegasus roundabout and Amberley south.

• Overview of our other work in North Canterbury

  Completed

  • New speed limits between Waikuku and Williams Street since December 2020 are helping people feel safer to walk, bike, or travel on the highway.
  • The signalised pedestrian crossing on SH1 near Woodend School is making it safer for school children and the local community to cross the highway.
  • New painted median at the northern and southern ends of Waikuku is providing extra separation for traffic and reminding people to slow down through the township, and around the Waikuku Beach Road intersection.
  • Median and side safety barriers along sections of the motorway between the Cam River and Tram Road are reducing the risk of head-on crashes and vehicles running off the road, and over-dimensional vehicles are now able to use the Ohoka Road offramp.
  • Resealing on SH1 between the Cam River bridge and the SH71 (Lineside Road) overbridge is completed and includes the addition of high performance line markings and additional ‘rumble strips’.

  Looking ahead

  • We will be looking at safety improvements between Saltwater Creek and Cam River as part of the SH1 Belfast to Pegasus Motorway and Woodend Bypass project.
  • The Woodend Bypass route is designated in the Waimakariri District Council’s district plan, and the land is protected for a four-lane highway. The government recently announced that this project will be prioritised for delivery as one of the first seven Roads of National Significance (RoNS).
