Seeing around 100,000 vehicle movements every weekday, the Kwinana Freeway is one of Perth’s critical transport corridors, with expressions of interest for the project now being called.
Proposed works aim to ease the journey for southern suburbs’ commuters and travellers to the South West.
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.
Federal Infrastructure, Transport, Regional Development and Local Government Minister Catherine King said, “Kwinana Freeway is one of Perth’s busiest transport corridors and is critical to ensuring the efficient movement of people and goods throughout the city.”
WA Transport Minister Rita Saffioti added, “Once complete the Kwinana Freeway Upgrade project will improve road safety and ease congestion for the growing residential, commercial and industrial precincts between Perth and Rockingham.”
Community and stakeholder engagement, utility surveys, geotechnical and environmental investigations are already underway and will provide the detail needed to inform road designs.
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 Federal and Western Australian governments, with each contributing $350 million.
Expressions of interest are now being called from suitably qualified design and construction businesses, which will then progress to the formal tender stage.
