Work is under way on Lancelin Road to provide safer travelling for drivers of heavy vehicles and other motorists on the coastal route.
Transport Minister Dean Nalder said the Leighton Opus Team had been awarded a $590,000 contract to build an extra lane near the intersection of Indian Ocean Drive and Lancelin Road.
"These important works will provide a southbound acceleration lane from the Lancelin Road intersection at Indian Ocean Drive, towards KW Road," Mr Nalder said.
"This will allow heavy vehicles turning south out of Lancelin Road to accelerate clear of the through traffic lane, leaving the through traffic largely clear of slow moving heavy vehicles."
The Minister said the work, due for completion by the end of June 2015, would improve the level of driver safety and reduce frustration for motorists moving between the coast at Lancelin and the Brand Highway via KW Road.
