Seventh & Third Avenue Bridges



We are replacing the ageing Seventh Avenue and Third Avenue timber  bridges with new concrete structures.

This project is being staggered to minimise disruption for road and rail users and local residents.

The new Seventh Avenue bridge in Maylands was built by Decmil-OHL and opened on 6 May 2015 by the Honourable Minister for Transport, Dean Nalder.  In late 2015, work will start on the Third Avenue bridge located in Mount Lawley.

Funding for this project is provided by the State Government.


Current status

With the Seventh Avenue bridge now open, we are working on the final planning for the Third Avenue bridge.  Tenders will be called mid-year and construction should start towards the end of 2015.

This bridge should take about eight months to complete.


Project Scope

The new bridge at Seventh Avenue spans more than 80 m while the Third Avenue structure will have a span of 22 m and will be built on its existing footprint.  Both include:

  • Improved turning and lane widths;
  • Accommodation for four rail lines;
  • Bridge guard rails and electrification screens;
  • Increased load capacity; and
  • Shared paths


Project benefits

Both bridges were built over 100 years ago and play a vital role in the local road network, linking Railway Parade and Whatley Crescent. 

The Seventh Avenue bridge carries up to 3,500 vehicles each weekday.

The Third Avenue bridge carries up to 10,000 vehicles each weekday and from December 2005 to December 2010, 56 crashes were reported on the bridge.

Replacing them ensures they meet current safety standards and allows for future road and rail improvements.
