Major upgrades to the Kwinana Freeway between Roe Highway and Safety Bay Road are another step closer but motorists have been warned to expect two years of delays during construction.
The $700 million project, jointly funded by the State and Federal Governments, is set to ease congestion and improve safety across Perth's southern suburbs.
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, while a new southbound lane will be added between Roe Highway and Berrigan Drive and a new northbound lane from Russell Road to Beeliar Drive.
New coordinated ramp signals will also be installed on the northbound ramps between Safety Bay Road and Roe Highway and median and verge barriers on both carriageways will be upgraded at key sections.
Preferred contractors for the project have been announced comprising of CPB Contractors, McConnell Dowell Constructors, Arup Australia Projects, and Jacobs Group.
Construction is set to begin in early 2027 and is expected to take two years to complete.
Transport Minister Rita Saffioti said drivers will experience some delays during construction.
“Additional lanes on freeways are always difficult to deliver, but it’s about trying to keep the existing traffic flowing as we deliver new lanes for future traffic,” she said.
“We apologise in advance. There will be inconvenience, but we’ll try and mitigate that inconvenience as much as possible through the use of on-site technology and also having our incident response teams available to clear any breakdowns or accidents as soon as possible.
"These upgrades will make a big difference to the daily lives of people commuting from our southern suburbs, as well as the growing number of people working in the commercial and industrial precincts between Perth and Rockingham."
