State Highway 35 (SH35) connects Gisborne to Ōpōtiki around the East Cape. The geography on this coastal route is unstable and highly erodible, and the road is vulnerable to failure — particularly during high rainfall and storm weather events.
We’d like to work with the community to create a prioritised plan for strengthening and stabilising some of the corridor’s most problematic slip and subsidence sites (places where the road is dropping out or slipping away). The length being considered for improvement in this project is approximately 196km, from Gisborne to Potaka.
What is a resilient road?
A resilient road can withstand adversities and remain open and functional through unforeseen events, as well as day-to-day. People, whānau and businesses still need to get to where they’re going, so we want our roads to absorb and withstand disruptive events.
A resilient road can perform effectively and adapt to changing conditions (including climate change) and recover quickly from disturbances.
About this project
The Tairāwhiti roading package, announced in 2018, includes $13.5m million for improving the resilience of SH35. Funded by the Provincial Growth Fund and the National Land Transport Fund, this project is about identifying and prioritising a package of resilience improvements to strengthen and stabilise the road, with works being delivered between 2020 and 2024.
As well as using traditional engineering techniques, we’d like to implement a native planting programme to reduce erosion, improve stability, and manage the moisture content in the ground because we know that network failures on SH35 are largely due to erosion.
