PILING works on the Old Mandurah Traffic Bridge Replacement project have been completed six weeks ahead of schedule.
In total, 128 piles were required for the bridge and boardwalks with an average of two piles completed each day.
Of these, 79 steel piles were installed in the estuary, as well as 49 concrete piles in the east and west embankments.
The steel piles were stored at the Mandurah Marina and towed upriver to the bridge site and piling barge as needed.
The piling barge has now moved out of the estuary and been dismantled.
Works on the bridge casting bay and launching structure are complete.
The launch nose will guide the bridge segments as they are pushed out from the casting bay on the western foreshore.
Main Roads WA project director Lambro Baros said the bridge works were progressing well.
“Georgiou has worked well to complete this major project milestone,” he said.
Mayor Marina Vergone said the completion of the piling works marked another step to delivering the project.
“It’s exciting to see the work progress through this critical phase and I must thank the community for their support during the piling work,” she said.
The first bridge segment, to be launched later this month, will mark the start of the next complex construction stage.
