Overnight closures on SH25 at Hikuai for essential bridge maintenance

State Highway 25, south of Tairua, will be closed overnight to all traffic for 5 nights between 8pm and 6am from Sunday 19 May. This is to allow for essential maintenance and repairs to the single lane Hikuai Stream bridge, just south of Tairua.

Affected road users will need to detour via SH25, looping through Coromandel township.

While this is essential maintenance work, we do appreciate this road closure involves a lengthy detour and will be disruptive.

This work is weather dependent.

NZTA explored the option of opening the road for a short period each night to allow convoys of traffic to pass, however this would impact work progress and extend overall disruption as additional night closures would be required.

Emergency services will be accommodated if required.

  • A variety of safety improvements across the Waikato have started, these will contribute towards making the roads safer. The programme of works includes a mixture of new and modified signage, new hazard warning signs, roadside safety/barrier guard rail, road widening, improved road lines and improved road markings. It is expected there will be minimal disruption for motorists while this work is completed. The works will take place until the end of June 2024. More information.
