The Brougham Street overbridge is a key part of the SH76 upgrade, providing a grade‑separated pedestrian and cycle crossing over one of Christchurch’s busiest freight corridors. It improves safety and reconnects communities divided by high traffic volumes, while supporting more efficient traffic flow and active transport links.
Brougham Street carries more than 45,000 vehicles per day and serves as the principal freight link between Christchurch and Lyttelton Port, making it a critical piece of transport infrastructure for the region. Historically, it has also created a significant barrier for pedestrians and cyclists, dividing communities and limiting safe crossing opportunities. The overbridge directly responds to these challenges by providing a fully grade-separated crossing.
During the site visit, participants will gain insight into the design, construction, and staging of this 36 metre single-span bridge, which has been prefabricated off-site and installed using complex crane lifts over a live state highway. The visit will highlight key engineering considerations including working within a constrained urban corridor, maintaining traffic flows on a high-volume freight route, and coordinating utility relocations and temporary works to enable safe construction delivery.
Join the Canterbury Branch for a site visit to the Brougham Street overbridge, gaining insight into the prefabrication, complex crane lifts and urban construction challenges of this 36-metre single-span structure.
