Construction of a permanent replacement for the storm-damaged Hikuwai Bridge on State Highway 35 between Tolaga Bay and Tokomaru Bay in Tairāwhiti will get under way this month.
“Cyclone Gabrielle damaged the original bridge, severing an important connection across the Hikuwai River, and local crews worked hard in the months that followed to reinstate access,” Transport Minister Chris Bishop says
“A temporary Bailey bridge has been in place since June 2023 while a long-term solution was designed.”
The new two-lane structure — about 100 metres long on the same alignment as the previous bridge — sits on a $50 million programme and is designed to keep the vital corridor between Tolaga Bay and Tokomaru Bay open in future storms.
“The new bridge will feature a modern, two-lane structure, be approximately 100 metres in length, and will follow the same alignment as the previous bridge.
“It will provide better flood and earthquake resistance, improved durability, and delivers environmental benefits. Once complete, it will provide a more efficient and permanent solution for SH35 road users for generations to come,” Bishop says.
Design changes aim to reduce blockages and damage during major weather events.
“The bridge has been designed to better withstand debris in the river with a wider central span and rounded piers, reducing blockages.
“Larger, deeper piles enhance resistance to flooding and erosion effects, while stronger columns boost structural durability. Improved bearings will also prevent the bridge deck uplifting when inundated and during earthquakes.”
The Transport Rebuild East Coast (TREC) Alliance has appointed CLL Service and Solutions to lead construction of the bridge structure, with local firms Parata Construction, Currie Construction and the Gisborne branches of Downer and Fulton Hogan involved in the works.
Early site establishment began last month. Cranes are now being set up and piling is due to start in late October.
“Cyclone Gabrielle severed more than a road in this part of the world – whole communities were cut off from Gisborne, and this much-needed bridge is a crucial part of delivering a resilient network for people and freight,” Bishop says.
“I look forward to this new bridge being completed as soon as possible. The East Coast was hit hard by Cyclone Gabrielle and restoring modern, resilient networks for people and freight is a priority for the Government.”
