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.
