Nearly half-a-billion dollars has been allocated in the upcoming State Budget in a bid to combat congestion along the Kwinana Freeway in Perth's southern suburbs.
About $460 million will be spent on widening the Kwinana Freeway between Roe Highway and Mortimer Road, addressing one of the worst congestion points on the freeway network.
This includes an extra lane in both directions between Russell Road and Mortimer Road, an extra lane southbound between Roe Highway and Berrigan Drive and an additional lane northbound from Russell Road to Beeliar Drive.
Co-ordinated ramp signals between Safety Bay Road and Roe Highway will also be installed to improve flow of traffic on the freeway.
"Like so many Western Australians who live south of the Swan River, I understand how frustrating it is to be stuck in congestion along Kwinana Freeway," Premier Roger Cook said.
"Given our State's booming economy and our growing population, we know this will continue to be an issue unless our government gets on with the job of fixing it."
Works are expected to begin in 2026/27.
The State Budget also includes $17 million of funding to build roundabouts at the intersections of Kargotich Road with Abernethy Road, Orton Road and Gossage Road, $7 million to install new traffic lights and an additional lane at the intersection of Baldivis Road and Kulija Road and $1.5 million towards the upgrade of the intersection of Nicholson Road and Warton Road.
