The WA Government’s upgrade of Kwinana Freeway has reached an important milestone with Expressions of Interest (EOI) now open for industry.
Kwinana Freeway is one of Perth’s critical transport corridors, supporting around 100,000 vehicles movements every weekday.
“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,” said WA Premier, Roger Cook.
“My government made a commitment during the election to make driving along the Kwinana Freeway easier – and by engaging with industry now, we’re getting on with the job of fixing it.
“These upgrades will do more than just ensure everyone in Perth’s south can easily use the roads they rely on to get to work or school, they will also support development of the Western Trade Coast and support my government’s Made in WA plan.”
The $700 million upgrade will target key pinch points along Kwinana Freeway including:
- A new lane in each direction between Russell Road and Mortimer Road (increasing from two lanes to three);
- A new southbound lane between Roe Highway and Berrigan Drive (increasing from four lanes to five);
- A new northbound lane from Russell Road to Beeliar Drive (increasing from three lanes to four); and
- New Coordinated Ramp Signals on northbound on-ramps between Safety Bay Road and Roe Highway, to smooth the flow of traffic on the Freeway at busy times.
Community and stakeholder engagement, utility surveys, geotechnical and environmental investigations are already underway and will provide the detail needed to inform road designs, the Government said in a statement.
Construction is expected to begin in early 2027 and be completed in 2029, subject to regulatory approvals.
The Kwinana Freeway Upgrade (Roe Highway to Safety Bay Road) is jointly funded by the WA and Federal Governments, with each contributing $350 million.
The EOI process will identify suitably qualified design and construction partners to progress to the formal tender stage.
