Here’s the latest on Tonkin Highway from credible sources:
A A$1 billion Tonkin Highway Extension and Thomas Road Upgrade project is underway in Perth, extending Tonkin Highway 14 kilometres south from Thomas Road to South Western Highway and duplicating part of Thomas Road. Construction moved into major works in late 2024/2025, with completion expected around late 2028. This expansion aims to ease freight movement, reduce local traffic on suburban streets, and improve travel times in Perth’s southeast corridor.[1][2][3]
The project is a joint effort funded by both federal and state governments, with the Australian Government contributing a substantial share, and it’s designed to support growth in Byford, Armadale, Kelmscott and Gosnells while aligning with METRONET’s Byford Rail Extension. Expected benefits include thousands of jobs and enhanced supply-chain efficiency.[2][8][1]
Major works include new interchanges, underpasses, roundabouts, cycling/pedestrian paths, and innovative equine crossings. Regional impacts include diverting heavy vehicles from local roads and improving connectivity to future residential and business precincts.[1][2]
Local updates note that some intersections (Hopkinson Road at Thomas Road) are closing as part of the THETRU package, signaling ongoing heavy construction in the area and the approach toward a phased completion through 2028.[5]
For broader context, sector updates indicate the Tonkin Highway Corridor project has ongoing environmental approvals, procurement activities, and design/construct milestones as of 2024–2025, with multiple related works in the pipeline to support the overall corridor upgrade.[4]
If you’d like, I can pull more detailed timelines, budget breakdowns, or create a concise one-page summary with key milestones and affected local areas. Would you prefer a timeline or a quick briefing for residents and commuters?
