Seventh & Third Avenue Railway Bridges


We are currently in the stages of replacing the ageing Seventh Avenue and Third Avenue timber railway bridges with new concrete structures.

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

The Seventh Avenue bridge located in Maylands will be replaced first, followed by the Third Avenue bridge located in Mount Lawley.

Funding for this project is provided by the State Government.


Current status

In early May 2014, Decmil-OHL JV was awarded a contract valued at almost $9.3 million to demolish and replace the old Seventh Avenue Railway Bridge.

The bridge is now closed and traffic has been detoured over the railway via the Caledonian Avenue level crossing and Third Avenue bridge, a map of the detour has been created to assist road users.  The new Seventh Avenue bridge should take about a year to complete.

To ensure the completed project recognises the heritage significance of the Seventh Avenue bridge, we are also working with relevant local community groups and the City of Bayswater to develop a public art proposal for the site.  The final public art will be installed once the new bridge is complete. 

For further information, please view the October 2014 Project Overview



To be built on their existing footprints, the new bridges at Seventh Avenue and Third Avenue will include:

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

The new bridge at Seventh Avenue will span more than 80m, while the Third Avenue structure will have a span of 22m.  Both bridges will include footpaths.



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 will ensure they meet current safety standards and allow for future road or rail improvements.



Demolition and construction of the Seventh Avenue bridge in Maylands started in May 2014 and will  take about a year to complete. The Third Avenue bridge in Mount Lawley will be demolished as soon as the Seventh Avenue bridge is complete, and should take a further eight months to complete.
