The Government is investing $7.5 million to replace two deteriorating culverts on Taranaki’s Forgotten World Highway and Surf Highway.
Funding from the Regional Infrastructure Fund includes $2.5m for the Toko Stream Tributary Culvert on State Highway 43 and $5m for the Whenuariki Stream Culvert on State Highway 45.
Design and consenting work is expected to begin within six months, with construction scheduled to start in 2027.
The Toko Stream Tributary Culvert is estimated to have about two years of serviceable life remaining.
The Government says its failure could close part of SH43 and force motorists to take a 50km diversion.
Regional development minister Shane Jones says replacing the culvert will help protect an important connection for communities, tourists and businesses.
“Culverts may not be sexy, but they are essential to keep our community links intact,” Jones says.
“The Forgotten World Highway is an important route for regional communities, tourists and businesses. They need infrastructure that is fit for purpose.”
The hand-dug Whenuariki Stream Culvert on SH45 is around a century old and has already partially collapsed.
Erosion is progressing towards the highway, and a complete failure could result in heavy vehicles facing a 133km diversion.
Transport minister Chris Bishop says replacing it before it fails will reduce the risk of significant disruption.
“The Whenuariki culvert has reached the point where replacement is the most sensible long-term solution,” Bishop says.
“By acting now, we’re reducing the risk of major disruption to road users and ensuring the Surf Highway remains a reliable route for years to come.”
Bishop says reliable transport infrastructure is critical to regional economic performance and the movement of people and goods.
Jones says the projects will improve network resilience, support local businesses and maintain connections throughout coastal Taranaki.
The Government says the two projects were selected based on regional need, delivery readiness, resilience and safety benefits, and their ability to progress to design and consenting within six months.
