What is a road rebuild ?Road rehabilitation is a process used to restore roads that have become worn out or damaged. It goes beyond simple repairs and involves rebuilding the road to ensure it remains safe and durable. Road rehabilitation involves:
• Removing the old road surface and damaged layers underneath. Road rehabilitation is important because it improves safety for all road users, reduces the need for ongoing maintenance and patch repairs, and supports key industries like freight and tourism by keeping transport routes reliable. It also ensures roads can withstand heavy traffic and changing weather conditions over time. SH3 Ōhaupo road rebuild February 2025 |

Thames - CoromandelWork starting soon State Highway 25 and State Highway 25A, road works and potential impacts to journeys. SH25 Thames Coast - closure: The deck replacement on Boundary Creek Bridge, between Te Mata and Waikawau, will see the road closed for 7 days from 5am Wednesday 29 October. Work to strengthen and repair the bridge supports is expected to take 10 weeks to complete. The road will remain open to traffic during this time, except for the 7-day closure at the bridge. Traffic lights and a temporary speed limit are in place while the work is carried out. While SH25 is temporarily closed, access will be maintained to all businesses and properties along SH25 up to the bridge from north and south, but there will be no through traffic. The detour is via SH25A to Hikuai and continue north via Tairua and Whitianga. For those heading south from Coromandel Town, reverse the route. More information. SH25A Kōpū Hikuai Road - closure: Daytime closures are needed on SH25A for 2 weeks in November for a major road rebuild. The work will take place from Monday 10 until approximately Friday 21 November, with the highway closed between 8am to 5pm Monday-Saturday. The closure points are SH26/SH25A at Kōpū and SH25/SH25A at Hikuai. All traffic through the closure points by 8am will get through before the daily closure. The road will reopen under single lane and stop/go each evening from 5pm and on Sunday 16 November. Delays can be expected.
