The US$74 million project to build a duplicate bridge is designed to reduce congestion at the crossing, which is used as the primary connection to the southern part of Mandurah and the Peel region in Western Australia.
Access for riders and walkers will also be improved with construction of a new shared path to improve connectivity on the southern underside of the new bridge deck. There will also be a platform to make recreational fishing more accessible to people of all ages and abilities.
Geotechnical site investigations, both on water and land, are under way, along with work to complete environmental and heritage assessments, project scoping and stakeholder consultation.
Western Australian transport, planning and ports minister Rita Saffioti said: “The duplication of the Mandurah Estuary Bridge will significantly improve congestion across the bridge, which I know can be frustrating for local residents and commuters.
“I'm pleased to see that more than 500 local jobs will be created and supported during the project, helping boost the local economy.”
