The State Government has delivered on their election promise to duplicate the Mandurah Estuary Bridge.
$55 million has been set aside for the project in the 2021-22 State Budget, with the Federal Government also committing $55 million.
The $110 million bridge will be built alongside the existing one, providing extra traffic lanes and support for the current structure, which is used as the primary connection to the southern part of Mandurah.
More than 500 local jobs will be created during the project.
Premier Mark McGowan said the new bridge will significantly reduce congestion as well as addressing safety issues with motorists merging prior to crossing.
“I know how frustrating this connection can be for locals, so I’m pleased we have fully funded this project," Mr McGowan said.
“The Mandurah Estuary Bridge is a key connection between Mandurah and its southern areas and as the population of our second city grows, so will the traffic using this structure.
“This was a key commitment at the election and I’m proud we are getting on with the job and delivering for the Peel region.”
More than 32,000 vehicles use the bridge each day, with 126 crashes over the five years ending 2020.
Early works are already underway including environmental and heritage assessments, preliminary site investigations, concept design and stakeholder consultation.
