Commonwealth Avenue Bridge Renewal Project – Permanent Works

Detail of Proposal 

The National Capital Authority (NCA) has received a works approval application for construction of new and upgraded infrastructure associated with the Commonwealth Avenue Bridge Renewal Project. The project involves bridge strengthening and widening of the shared paths to cater to Canberra’s long-term transport needs while maintaining the bridge’s heritage value.

The proposed works included in this application are: 

• Bridge strengthening including replacement of the existing bearings and reinforcement with high-strength concrete and cabling.
• Widening of the shared paths along the bridge from the existing 2.4 metres to 5 metres.
• Improved shared path access with new connecting paths and replacement of the existing stairs.
• New lighting across the length of the bridge including within the shared path handrails.
• New landscaping to complement the landscape setting of Canberra including additional trees, grasses and groundcovers, shrubs and feature plantings.

The plans and supporting documentation for the application can be viewed below. 

Please note this works approval application relates only to the permanent works associated with the project. 

Temporary works including traffic management associated with the construction phase of the project will be subject to a separate works approval application.
