As part of the Road to Zero speed and infrastructure programme, Waka Kotahi is making the stretch of State Highway 1 between Cambridge and Piarere safer.
SH1 between Cambridge to Piarere is part of one of the country’s most important transport corridors. The Auckland-Hamilton-Tauranga corridor accounts for a significant proportion of all road freight in New Zealand.
A programme of safety improvements is underway to reduce the number of serious crashes along this section of state highway, including flexible median barriers, six turnaround bays and a new roundabout. The project is being delivered in three stages as follows.
We’ve looked at the types and causes of crashes on SH1 and identified improvements that puts the safety of people first.
The proposed improvements mean people will have to change the way they use the road in the future, but they will save lives and reduce the number of people killed or seriously injured on this road.
The turnarounds and median barriers, along with roundabouts at the SH1/Karāpiro and SH1/SH29 intersections, will make this stretch of SH1 much safer, reducing the risk of head-on crashes.
