Here’s the latest on Tonkin Highway based on recent public reporting:
- Updates on the Tonkin Highway Extension and Thomas Road Upgrade (THETRU) project ongoing in south-east Perth include a contractor finalized for the long 14-km extension, with works focused on a four-lane dual carriageway and multiple grade-separated interchanges. This milestone aligns with a broader plan to improve travel times and safety in the corridor.[3]
- Environmental and procurement processes have progressed, with the Environmental Protection Authority (EPA) finalising its report and conditions for approval, and procurement activities (including an Expression of Interest) having kicked off in late 2024, signaling preparedness for a Design and Construct contract in mid-2025. The project is jointly funded by Australian and Western Australian governments, with the total project value in the vicinity of hundreds of millions to over a billion dollars depending on scope segments.[1]
- Local council and state planning updates indicate continuing works with related traffic adjustments, including road closures associated with the upgrade, such as certain intersections like Hopkinson Road being closed as part of the THETRU works, which will affect local access during construction.[4]
- Recent traffic disruptions have occurred on Tonkin Highway due to incidents, with reports of northbound closures and crashes affecting congestion and prompting detours; authorities advise checking live traffic updates for alternate routes when incidents arise.[5]
- Visualizations and public-facing briefings released in 2025 show project concepts and planned enhancements, including fly-throughs of the Tonkin Highway Extension and Thomas Road Upgrade to illustrate the anticipated end-state once construction is complete.[8]
If you’d like, I can pull the most up-to-date official statements or local news links for your specific area in London, or summarize the key milestones (scope, timelines, funding) in a concise timeline. I can also look for live traffic advisories for Perth if you’re planning a trip there.
Would you like me to fetch the latest official jurisdiction announcements or provide a compact milestone table?
