Construction works for the Mandurah Estuary Bridge Duplication in WA are now underway, including a second two-lane bridge built on the existing traffic for additional lanes.
Work is underway on the Mandurah Estuary Bridge duplication, with the sod turned on this important project to slash congestion in Mandurah and Dawesville.
The project will involve a second, two-lane bridge being built on the south side of the existing structure. This will provide additional traffic lanes for the original bridge, which is the main traffic access to southern Mandurah.
A new four-metre-wide shared path will also be built to help the local community better access recreational activities, including fishing.
More than 33,000 vehicles currently use the existing Mandurah Estuary Bridge every day, with congestion an ongoing issue, particularly during the busy holiday seasons.
“This project has been long awaited by the local community and I am very pleased that work is now underway on this key election commitment,” says WA Premier Roger Cook.
“Duplicating the bridge will significantly reduce congestion that is currently experienced on approach to the bridge and cut travel times for the thousands of commuters who use the bridge each day,” says WA Premier Roger Cook.
“This bridge is not just an essential piece of infrastructure, but a vital link between families, businesses and communities which will soon experience better and more reliable transport connection between northern and southern Mandurah,” says Federal Infrastructure, Transport, Regional Development and Local Government Minister Catherine King.
Originally constructed in the 1980s, the Mandurah Estuary Bridge was designed with future duplication in mind.
The bridge will be built utilising the incremental launch method.
A total of 15 concrete bridge segments will be constructed on site and incrementally launched across the estuary from the south-eastern embankment.
“The duplication of the bridge will reduce congestion, improve safety and bring about time savings for people who need to commute in and out of Mandurah,” says WA Transport Minister Rita Saffioti.
“This bridge experiences high traffic volumes with around 33,000 vehicles per day due to the population growth in the Mandurah and Peel regions, so the duplication will address these issues,” says WA Transport Minister Rita Saffioti.
“Duplicating this critical bridge will provide Mandurah road users smoother, safer, faster and better access between the north and the south of the city,” says Senator for Western Australia Louise Pratt.
“The Australian Government will continue to invest in infrastructure like duplicating the Mandurah Estuary Bridge to support liveable, safe and healthy communities across Western Australia,” says Senator for Western Australia Louise Pratt.
“I made a commitment to deliver this bridge duplication for the people of the Dawesville electorate, and that is what we are doing,” says State Member for Dawesville Lisa Munday.
“Duplicating this bridge will make the daily commute smoother and safer for residents south of Mandurah and surrounding communities, and remove a frustrating pinch point on our road network,” says State Member for Dawesville Lisa Munday.
This is expected to be completed by late-2025.
The $136 million project is jointly funded by the Australian and Western Australian Governments, with each contributing $68 million.
