One of Western Australia’s most significant road infrastructure projects has reached a critical milestone, with a contract now awarded
A contract to deliver the $1 billion Tonkin Highway Extension and Thomas Road Upgrade of south-east Perth has been awarded to the Tonkin Extension Alliance consortium, which includes BMD, Civcon Civil and Project Management, Georgiou Group, BG&E and GHD.
The 14-kilometre extension of Tonkin Highway will include a four-lane dual carriageway from Thomas Road all the way to South Western Highway, including a number of grade-separated interchanges, underpasses and roundabouts.
The project will also cater for the recreational needs of the area, with several equine underpasses, and a new principal shared path along the entire 14km extension.
Local communities in Byford, Armadale, Kelmscott and Gosnells will also benefit, which currently see large volumes of heavy vehicles on local roads.

“The Tonkin Highway Extension and Thomas Road Upgrade project will ease traffic pressure on local roads, making them safer and reducing travel times for our community,” Darling Range state member Hugh Jones says.
“This project will better connect our fast-growing suburbs to jobs and education opportunities while improving safety for local families.”
Upgrades to Thomas Road will include duplication of 4.5-kilometres between Kargotich Road and South Western Highway, a new principal shared path and upgrades to a number of local intersections including Kardan Boulevard, Masters Road and Plaistowe Boulevard.
Construction of the project is scheduled to commence in mid-2025 with completion anticipated by late-2028.
