“The January storm events left us with a gaping hole in SH25A and the daunting task of reconnecting the Coromandel as soon as possible,” says Jo Wilton, Regional Manager of Infrastructure Delivery for NZ Transport Agency Waka Kotahi (NZTA).

“The new bridge isn’t just the fastest solution, it’s the most resilient solution too and it’s a tremendous feeling to see it opened and unwrapped today, just in time for Christmas.”

Drivers may see workers updating SH25A road signs around the Coromandel Peninsula today and should drive with care.

“The area around the bridge remains an active worksite with work underway until around April 2024. Drivers should be aware there is a speed restriction and areas of new seal along the road. Please follow all posted speeds to protect your vehicle and the new work.”

The traffic management at the new bridge is there to safeguard vehicles from parts of the site that aren’t complete and to allow workers safe access when they return after the Christmas, New Years break.

Traffic is expected to be heavy throughout the holiday period and NZTA needs everyone to do their bit to keep things flowing smoothly.

“We understand there will be a lot of interest in the new bridge and changed landscape at the slip site, but it is not safe to stop and sightsee on or near the bridge. Road users need to keep moving,” Ms Wilton says.

“Any closure of SH25A, whether it’s weather or crash related, has widespread impacts, so be tolerant, keep a safe following distance and be conscious of those travelling behind you.”

In addition to the new bridge, road users can now enjoy a safer journey along the whole length of SH25A.

“We’ve also taken the opportunity with the closure of the road to invest an additional $30 million to clear slips, replace 23 culverts, repair/replace 7km of side drains and complete the strengthening of 7 bridges as well as complete slope stabilisation and resealing along the rest of SH25A to ensure the entire corridor is safe and more resilient.

“We’d like to thank the Coromandel community for their support of the project and we hope everyone enjoys a wonderful holiday under a Pohutukawa on the Peninsula this summer.

“Let Santa know the highway’s open and he doesn’t need to take the long way around.”
