PILING works have begun for the Old Mandurah Traffic Bridge Replacement project.
The lower impact piling works will continue for the next two weeks.
From July 25, residents and businesses are warned to expect increased noise and disruption as work begins.
The critical construction stage will continue until November and effort will be made to minimise impact on the community.
Main Roads WA project director Alastair Cowan said the early bridge works were progressing well.
“The piling work, to form the below water and underground bridge support structure, will be intensive as it involves ‘hammering’ steel tubes or solid concrete beam lengths into the ground,” he said.
About 129 piles are required for the bridge and boardwalks with an average of two piles completed each day.
Piling will be carried out Monday to Saturday between 7am and 7pm but it is not a continuous construction activity and the noise varies depending on ground and wind conditions as the piling moves across the estuary.
A marine animal observer will monitor dolphin activity and work will stop when dolphins are in the area.
Mr Cowan said a regular piling schedule would be available from the Have Your Say Mandurah website each Tuesday to enable residents and businesses to plan around the noisy activity.
The schedule should be used as a guide only as timeframes could vary because of dolphin interactions and other unforseen delays.
