Information about planned maintenance work and projects to improve the state highways in the Taranaki region.

Maintaining your roads

This construction season we are undertaking a bumper programme of work to address as many issues on the Taranaki network as possible. From January to April, you’ll see a lot activity on the road particularly on State Highway 3 north and south bound, and in New Plymouth CBD.

While we aim to do this work with as little disruption as possible, there will be delays to journeys. We encourage motorists to plan ahead using the journey planner to minimise delays.

Please drive carefully through work sites, keep to the temporary speed limits and be respectful of our crews who are working hard to maintain the roads.

Works planned for this summer

The map below shows the maintenance and safety and resilience projects programmed for the 2020/2021 construction season.

Please note that our ability to complete works is heavily dependent on the weather. We need dry, warm conditions to rebuild and resurface roads or the new seal won’t stick to the road surface properly and the work will need to be redone. However, we’re committed to doing everything we can to complete our programme and improve Taranaki state highways.
