The new Mandurah Traffic Bridge has officially opened all four lanes just in time for Christmas with Hon. Minister Rita Saffioti opening the bridge on Friday, 15 December.

Georgiou first opened the bridge to two lanes of traffic under restricted conditions in September 2017.

The stunning curved structure was built in 13 segments on the western foreshore with the team utilising the incremental bridge launch method to push the bridge over the estuary.

Despite its simplistic appearance, the new Mandurah Traffic Bridge proved to be a complex job for our Engineering team with various challenges to ensure the curves aligned across all three cross sections.

“The design of the new bridge was complex and the construction challenging,” explained Project Manager Anthony Deurloo.

“The structure is curved in three directions – it’s curved in elevation, in plan and, in cross-section, it has a curved soffit.

“It was a very technical build. The casting bed framework we created was an extrapolation of the constant curve and the tolerances that we had to construct to were very tight. The cross section of the bridge was also rare; it’s asymmetrical as it features a lowered pedestrian footpath on one side.

“From an engineering point of view, it’s been rewarding and satisfying but a rather difficult build.”

Mayor of the City of Mandurah Rhys Williams said completion of the roadworks for the Old Mandurah Traffic Bridge Replacement project marks a significant milestone for the Mandurah community as they have worked hard over a number of years to develop and implement a plan to replace the old bridge.

“The project has been a well-orchestrated partnership between the City of Mandurah, State Government and the design and construction contractor, Georgiou Group.”

Georgiou is now focusing on the demolition of the old bridge which is about 60 percent complete.

Remaining works on the new bridge structure include completion of footpaths, feature boardwalks underneath the bridge and landscaping which will continue through to February 2018.
