Old Mandurah Bridge Replacement


Latest news

Two lanes of the new Mandurah Bridge were opened to traffic on Wednesday 20 September as part of the Old Mandurah Traffic Bridge Replacement project.

Road users can now use the new bridge in both eastbound and westbound directions, with an additional two lanes scheduled to open in December. At this time, cyclists will also be able to ride on the roadway of the new bridge.

The Old Mandurah Traffic Bridge is now permanently closed and Mandurah Terrace has been re-opened to traffic.

Works to demolish the old bridge will begin as a result of the new bridge opening. This work will take about two months to complete.
Some components of the old bridge will remain as a feature within the water on the west of the estuary. A section of the old bridge will be retained on the east of the estuary and will be incorporated into the fishing platforms and boardwalk.

The State Government and City of Mandurah provided $51.8 million for the project.

The Old Mandurah Bridge on Old Coast Road in Halls Head has approached the end of its life. The two-lane structure is no longer sufficient to cater for local traffic due to the increased population growth in the area. Following work by a Community Reference Group (CRG) to develop a business case in 2013, the State Government and the City of Mandurah developed the project to replace the existing traffic bridge.


The Community Reference Group (CRG)

A CRG established by the Minister for Transport in November 2012 ensured the community was well-represented during the redevelopment of the Old Mandurah Bridge. The CRG comprised members across local government, industry and community interest groups in addition to a team of specialist technical advisors. The group published a Strategic Business Case in July 2013 identifying those issues most important to the local community and proposing a preferred option.


Scope of works

The OId Mandurah Traffic Bridge Replacement project features include:

  • Four traffic lanes;
  • Separate wide pedestrian and cyclist walkway to the north side of the new bridge; and
  • Fishing platforms and boardwalks accessible from the eastern and western foreshores

Consultation to identify community issues and preferences was undertaken in 2012/13, and the information collected was used to develop the project scope given to industry to base detailed bridge proposals on.

Information about the project will be distributed through a number of channels including fact sheets, the City of Mandurah’s and our website, and local newspapers as it becomes available.
