Works are now underway on the $31 million Wanneroo Road (Joondalup Drive to Flynn Drive) Dual Carriageway, which will relieve congestion for motorists travelling along Perth's northern corridor.
Western Australian Transport Minister Rita Saffioti said the project, together with two interchange projects on Wanneroo Road, would lead to safer, more efficient journeys.
"It will also support the expansion of the industrial corridor in Perth's north, which will help with job creation and new business opportunities," Ms Saffioti said.
"The delivery of each project will be carefully co-ordinated by Main Roads in partnership with the local community to minimise disruption to our road network during the period of the works."
Federal Member for Pearce Christian Porter said the upgrade would remove the bottleneck 26,000 vehicles experience each day on Wanneroo Road.
"The upgrade will also significantly improve safety and support the ongoing development of Wanneroo Road as a major north-south alternative to the Mitchell Freeway," Mr Porter said.
"It will cater for the increasing volumes of traffic generated by the growing population in Perth's north-west metropolitan corridor and provide efficient connectivity for industry servicing the expanding Wangara and Neerabup industrial parks."
This is the first of three major upgrades on Wanneroo Road, with construction on the new interchanges at Joondalup Drive expected to start mid-2018 and Ocean Reef Road expected to start late 2018.
Construction of the Wanneroo Road widening project is a key milestone in the delivery of 17 new road projects resulting from a $2.3 billion Australian and Western Australian Government investment in road and rail infrastructure.
The Wanneroo Road (Joondalup Drive to Flynn Drive) Dual Carriageway is a jointly funded project with the Australian Government contributing $24.8 million and the Western Australian Government contributing $6.2 million.
