The contract to deliver the $1 billion Tonkin Highway Extension and Thomas Road Upgrade Project, in Western Australia, has been awarded to a consortium containing some of the largest infrastructure providers in the country.
The contract to deliver the project has been awarded to the Tonkin Extension Alliance consortium which includes BMD, Civcon Civil and Project Management, Georgiou Group, BG&E, and GHD, bringing together a wealth of expertise and experience to deliver one of Western Australia’s most significant road infrastructure projects.
The 14-kilometre extension of the 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.
Upgrades to Thomas Road will include duplication of 4.5-kilometres between Kargotich Road and South Western Highway, new principal shared path and upgrades to a number of local intersections including Kardan Boulevard, Masters Road and Plaistowe Boulevard.
The project will deliver benefits to Western Australia’s freight and logistics network by creating a high-standard north-south transport link, improving road safety, freight efficiency, and connectivity for residents, businesses, and commuters.

Construction of the project is scheduled to commence in mid-2025 with completion anticipated by late-2028.
WA Deputy Premier and Minister for Transport Rita Saffioti said the project will make the journeys of people in the south-eastern corridor faster and safer.
“The extension of Tonkin Highway will be a game-changer for the movement of freight to and from the South West and Wheatbelt, and provide a safer road network for people living in suburbs like Byford, Armadale, Kelmscott and Gosnells who currently contend with large volumes of heavy vehicles on local roads,” Saffioti said.
“This extension complements METRONET’s Byford Rail Extension and other safety improvements in the area, ensuring better access to our transport network for communities in the south.”
The project is expected to support around 4400 direct and indirect jobs.
