Kennedy Highway (Cairns - Mareeba), Barron River bridge upgrade, planning

The Barron River bridge planning project will investigate long-term solutions for the bridge near Kuranda.

The bridge over Barron River near Kuranda is a 257m-long, high-level bridge that opened to traffic in 1963. In October 2020, inspections identified fatigue cracks in some steel elements of the bridge.

These cracks were caused by many years of impacts from heavy vehicles, which are now much heavier than when the bridge was designed and built in the early 1960s.

We have successfully carried out investigations, testing and repairs to ensure the bridge is safe for vehicles under 50.5t. A regular monitoring and testing program ensures the bridge remains safe.
