I don’t have live access to current news in this moment, but here’s what’s been reported recently about the Tonkin Highway project in Perth:
- A major expansion project known as the Tonkin Highway Extension and Thomas Road Upgrade has progressed into the major works phase, with a $1 billion price tag and a plan to extend Tonkin Highway by about 14 kilometers south from Thomas Road to South Western Highway. This aims to alleviate local congestion and boost freight efficiency and is expected to complete around 2028.[1][4][6]
- The project includes new grade-separated interchanges, underpasses, roundabouts, and a principal shared path, plus equine crossings to accommodate local users. It is jointly funded by Federal and Western Australian governments, with the Albanese government contributing the majority of the funding.[4][1]
- Groundwork began with site establishment and traffic realignments in 2025, and contractors were appointed to deliver the extension and related upgrades. The works are planned to complement METRONET’s Byford Rail Extension for integrated road–rail improvements in the southeast corridor.[6][1]
- There have been related updates and milestones along the way, including official sod-turning events, project milestones in the WA press, and local government notices about intersections and closures associated with the THETRU program.[2][5]
If you’d like, I can pull the latest official project updates from Western Australia’s Main Roads site or METRONET pages and summarize any new milestones, contractor changes, or completion-date shifts. I can also track any major incidents or road closures impacting Tonkin Highway traffic in the Perth area.
