The 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. The proposed works will 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.
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 Albanese and Cook Labor governments, with each contributing $350 million.
The EOI process will identify suitably qualified design and construction partners to progress to the formal tender stage.
