Construction contract awarded for Kwinana Freeway upgrade

Construction will begin early next year to upgrade more than 29 kilometres of Perth's Kwinana Freeway between Roe Highway and Safety Bay Road. A contract to deliver the project has been awarded to a consortium comprised of CPB Contractors, McConnell Dowell Constructors, Arup Australia Projects and Jacobs Group. Detailed design will now begin on 11 kilometres of widening from Russell Road to Mortimer Road, an additional lane southbound from Roe Highway to Berrigan Drive, and an additional lane northbound from Russell Road to Beeliar Drive.

New coordinated ramp signals will be installed on 11 northbound ramps, which will create 42 kilometres of continuous smart freeway from Safety Bay Road to the Narrows Bridge. The $700 million Kwinana Freeway Upgrade, jointly funded by the Albanese and Cook Labor Governments, will ease congestion and improve safety across Perth's southern suburbs. The project will increase capacity on Kwinana Freeway enabling a smoother flow of traffic and helping to reduce travel times.

The project is expected to support up to 4,180 local jobs. Construction will begin in early 2027 when environmental approvals are complete. Project completion is scheduled for mid-2029, with significant sections of completed widening to be opened by late 2028.

Quotes attributable to WA Premier Roger Cook: "Delivering the Kwinana Freeway widening project is another example of my WA Labor Government putting WA first. "As one of Perth's busiest roads, we know that once complete this project will have a big impact on the thousands of drivers who use the Kwinana Freeway to get to school, work and home. "Working with the Albanese Labor Government, we are delivering quality infrastructure across our State to support a high quality of life for all Western Australians." Quotes attributable to Federal Infrastructure, Transport, Regional Development and Local Government Minister Catherine King: "Our government is committed to creating safe, reliable infrastructure to serve the people of Western Australia for years to come.

"The Kwinana Freeway upgrade will transform one of Perth's busiest road corridors, adding capacity and making journeys safer and smoother." Quotes attributable to WA Deputy Premier and Minister for Transport and Major Infrastructure Rita Saffioti: "We're getting on with the job to widen the Kwinana Freeway and cut travel times for communities across our southern suburbs.

"With more than 100,000 road users every weekday, these upgrades will make a huge difference to families going to work and school, and to truck drivers delivering essential goods. "We've invested more than $1 billion in upgrades to the Kwinana Freeway, including around Cockburn, and this is another project to support the community in this growing corridor. "Together with the Albanese Labor Government, we're delivering major infrastructure projects right across our State and generating quality jobs for Western Australians in the process." Quotes attributable to Federal Member for Brand Madeleine King: "This is another practical example of how Federal and State Labor are delivering real benefits for families and workers in Perth's southern suburbs.

"By adding extra lanes and upgrades to Kwinana Freeway, workers and families will spend less time in traffic and more time with loved ones. "Labor is delivering real benefits for the people of Rockingham, Kwinana, and suburbs like Warnbro, Port Kennedy, and Baldivis."
