Billion-dollar Tonkin Highway contract confirmed

The Tonkin Highway and Thomas Road upgrades form a key part of the future of freight movement in metropolitan Western Australia

The contract to complete the $1 billion Tonkin Highway Extension and Thomas Road Upgrade Project in south-east Perth has been awarded, with the Tonkin Extension Alliance consortium selected to complete the project.

The consortium includes BMD, Civcon Civil and Project Management, Georgiou Group, BG&E, and GHD, and will deliver one of the most significant road infrastructure projects in the state’s history.

The extension of Tonkin Highway will include a four-lane dual carriageway from Thomas Road to the South Western Highway, including multiple grade separated interchanges, underpasses and roundabouts.

Upgrades to Thomas Road will include duplication of 4.5-kilometres between Kargotich Road and South Western Highway and upgrades to a number of local intersections including Kardan Boulevard, Masters Road and Plaistowe Boulevard.

The crucial road upgrades are part of an overall transformation of the freight capacity of Perth’s south-east region, which includes the movement of the city’s container port from Fremantle to Kwinana.

“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,” WA Minister for Transport Rita Saffioti says.

“The 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.”

Construction of the project is expected to commence in mid-2025 and support over 4000 direct and indirect jobs.

Currently, it is expected to be complete by late-2028.

“This project will deliver significant 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,” Federal Minister for Infrastructure, Transport, Regional Development and Local Government Catherine King says.

“The project is part of a broader investment to the Tonkin Highway that will deliver a high-standard north-south transport link, including key upgrades such as the Tonkin Highway Gap.”
