SH25A day closures ending early

The current day closures on State Highway 25A (SH25A) across Coromandel are ending today, Tuesday 18 November.

Monday-to-Saturday closures have been in place since 10 November for a major rebuild in the steep and narrow sections of the state highway.

The road will reopen by late afternoon today or earlier.

NZ Transport Agency Waka Kotahi (NZTA) Regional Manager Maintenance and Operations, Roger Brady, says the early finish is thanks to the teams on the ground.

“Our teams made the most of fine weather and good planning and resourcing to get work completed several days ahead of schedule – allowing the road to reopen sooner than anticipated.''

There is still some work to complete but it can be done under speed restrictions and occasional stop/go.

"We acknowledge the disruption the closure caused the community and businesses, and we thank everyone for their understanding and patience,” Mr Brady says.

“Getting the work completed and the road reopened before the peak summer holiday period was a priority.

“Our contractors have been very busy all spring and early summer across the Coromandel Peninsula ensuring the roading network is safe and resilient for this summer and years ahead.”

What was done during the closure:

• A significant road rehabilitation upgraded both the drainage system and the road surface, improving long-term resilience and safety.

• The project covered 480 metres of road, including 3600m² of chip sealing, delivering an even and more durable surface for road users.

• Crews completed 5 mill-and-fill patches, restoring pavement strength and quality.

• A reinforced wall was built near Troop Falls.

During the closure more than 200 individual maintenance jobs were done, including edge break, shoulder and pothole repairs, vegetation control, signage maintenance, culvert clearing and other drainage and surfacing work.

Whangamatā bridge work going well

Urgent deck work is progressing well on the Moana Anu Anu Bridge (also known as the Wentworth Bridge) on SH25, southwest of Whangatmatā.

The bridge closed to all traffic late last month and is on track to open again on Tuesday 9 December. The closure runs 24/7.

The repairs include a full deck replacement, new safety barriers, resurfacing and other work which can be done during the closure.

The detour through Whangamatā uses Mayfair Avenue and Martyn Road, adding only a few minutes to normal journey times.
