Update 10 September 2021

The project is currently in the development and planning phase. Activities during this phase include further development of the preliminary design option to strengthen the load bearing capacity of the Bridge, upgrade the vehicle and pedestrian barriers and widen the shared path.

Consultation with the ACT Government and utility service providers has commenced and consultation with the community and other stakeholders has commenced and will continue through the detailed design stage.

Timing of the works will be coordinated with the ACT Government and is currently scheduled to commence in 2023 and phased to minimise disruption to the community.

Commonwealth Avenue Bridge Upgrade

On 27 January 2021 the Australian Government announced a $137m investment to upgrade Commonwealth Avenue Bridge (the Bridge) to extend the life of the Bridge by another 50 years. Infrastructure Australia included the Bridge Upgrade on their Infrastructure Priority List in late 2020. The NCA will be managing the project.

Some key notes about the project:

  • The Bridge is one of two major bridges crossing Lake Burley Griffin and is a critical component of the transport network of Canberra and the Australian Capital Territory (ACT) overall. The Bridge also has considerable cultural and heritage value.
  • The Bridge was built in the mid-1960s. Since its opening, patronage on the Bridge has grown substantially. Current traffic on the Bridge makes it one of the busiest transport assets in Canberra.
  • The project will strengthen and widen the Bridge. The project will increase the load bearing capacity of the current Bridge to reflect current and forecast traffic load demands.
  • The vehicle and safety barriers will be upgraded, and the Bridge will be widened to accommodate wider active transport lanes for pedestrians and cyclists.

Road and lake closures will be advised as the project progresses.
