The Government has confirmed that upgrades to SH76 Brougham Street in Christchurch will be prioritised as a Road of Regional Significance, with construction set to begin by mid-2025.

The project includes a long-awaited overbridge between Collins and Simeon Streets, aimed at improving safety and reducing congestion.

Transport Minister Chris Bishop said the designation reflects the Government’s commitment to boosting economic growth, productivity, and transport efficiency in Christchurch and the wider South Island.

“Carrying over 45,000 vehicles per day, SH76 Brougham Street is a critical route servicing commercial, industrial, and residential areas south of Christchurch. It is also the main freight route to the South Island’s largest port at Lyttelton,” Bishop said.

MP for Wigram Megan Woods called the decision a win for the local community.

“The National Government’s decision to cut the funding for this project was always wrong and frankly ridiculous. It never stacked up and this is a point I have made repeatedly to Ministers. The community have also made that point loud and clear to the Government.

“I am thrilled that Addington kids will now have a safe way to get across a state highway to school.”

Banks Peninsula MP Vanessa Weenink welcomed the announcement, saying the project will bring long-term benefits to the region.

“This investment will improve efficiency and safety, make travel times more reliable, and support economic growth across the South Island,” Weenink said. “Residents and businesses have made it clear that this is an important route, and I am pleased the Government is delivering certainty for them.”

The Government previously funded only the pre-implementation phase of the project, allowing for design work, strategic property purchases, and consenting processes to progress. Now, full funding has been approved, and the New Zealand Transport Agency (NZTA) will oversee the project’s delivery.

The overbridge, expected to be completed within two years, will provide a safer crossing for local residents and school children, eliminating the need to use the existing level crossing. Other upgrades along the corridor will focus on improving intersections, easing congestion, and enhancing freight movement to and from the port.
