- Shortlisted contractors and consultants invited to submit detailed proposals for Kwinana Freeway upgrades
- Upgrades to accommodate increased traffic demand and growth across southern corridor
- Cook Government committed to delivering quality infrastructure across WA
The Kwinana Freeway upgrade has reached another major milestone with shortlisted contractors and consultants invited to submit detailed proposals to deliver the project.
With about 100,000 vehicle movements every weekday, Kwinana Freeway is one of Perth's critical transport corridors.
The vital upgrade will futureproof Kwinana Freeway to accommodate significant growth and rising traffic demand from residential and industrial development in the southern metropolitan region.
By targeting key 'pinch-points' along the route, the upgrades will reduce peak-hour congestion, improve safety, and cut travel times along the busy corridor.
New lanes will be added to key sections of the freeway, including a third lane in each direction for the 11-kilometre stretch between Russell Road and Mortimer Road.
Co-ordinated ramp signals will be installed on northbound on-ramps to actively manage and smooth traffic flow during peak periods.
More than 1,960 crashes were reported on the freeway between January 2020 and December 2024.
The majority were rear-end crashes with the congested, stop-and-go nature of the traffic along the freeway creating unpredictable conditions for drivers.
The concept design outlining the configuration and location of additional lanes, shared path connections, and proposed new or modified noise walls has been developed and will continue to be progressed throughout 2026.
Construction will commence in 2027, subject to regulatory approvals.
The $700 million Kwinana Freeway upgrade (Roe Highway to Safety Bay Road) is jointly funded by the Albanese and Cook Labor Governments.
As stated by Premier and Kwinana MLA Roger Cook:
"Congestion along the Kwinana Freeway during peak periods is a major source of frustration for members of my community, and commuters in Perth's southern suburbs.
"Reaching the next step of the election commitment to widen the Freeway helps meet my government's priority to deliver quality infrastructure across our State through improving our road network.
"These upgrades also support my government's Made in WA plan and the development of the Western Trade Coast."
As stated by Transport Minister Rita Saffioti:
"We're transforming Kwinana Freeway to slash peak-hour travel times and improve safety for commuters using this busy transport corridor.
"By adding additional lanes and smart traffic management, road users will experience a smoother and safer journey during peak periods.
"This project will also unlock opportunities for more residential, commercial, and industrial development, supporting local jobs and families in our southern suburbs."
