Groundwork for the project such as community and stakeholder engagement, utility surveys, and geotechnical and environmental probes are already in progress.
These preliminary activities are intended to shape the final road designs.
Subject to obtaining the necessary regulatory approvals, the commencement of construction work is anticipated in early 2027, with a projected completion date in 2029.
WA Minister for Transport Rita Saffioti said: “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.
“The Kwinana Freeway Upgrade follows the recent opening of the new Thornlie-Cockburn rail line and represents our ongoing investment in improving the transport network across Perth’s southern suburbs.”
Funding for the Kwinana Freeway Upgrade is being shared equally between the Albanese and Cook Labor governments. Both governments have committed A$350m each to the project.
The EOI process is designed to shortlist competent design and construction companies that will be invited to proceed to the subsequent tendering stage.
