Commonwealth Avenue Bridge

This is a proposal for upgrading Canberra’s Commonwealth Avenue Bridge, one of two major crossings over Lake Burley Griffin that are vital to the capital’s transport network. The bridge was originally constructed in the early 1960s to a 1950s design. The proposed project aims to increase the load-bearing capacity of the current bridge to handle current and expected future traffic, and to extend the design life by at least 50 years. It is also proposed to upgrade the vehicle and pedestrian safety barriers and widen the bridge to meet modern design standards.

The business case was accepted for Infrastructure Australia's evaluation on 20 March 2020.

On 3 September, Commonwealth Avenue Bridge Project was added to the Infrastructure Priority List as a Priority Project.
