​Old Mandurah Bridge Replacement

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

Latest news

All four lanes of the new Mandurah Bridge were opened to traffic on Friday 15 December.

Road users can now use all lanes on the new bridge. Cyclists are now also able to ride on the roadway of the new bridge.

The Old Mandurah Traffic Bridge is now permanently closed and works to demolish the old bridge are in progress. 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.

Some footpath detours remain in place on the eastern and western foreshores, while landscaping, fishing platform and boardwalk works are completed.
