Thomas Road Upgrade Thomas Road to Nicholson Road Safety improvements

A number of upgrades have been completed along Thomas Road, delivering safer and smoother travels in Perth's south-east.

The improvements support the large volume of traffic in the fast-growing area, travelling to and from the South West and Wheatbelt regions.

The program of works were delivered in late-2024, with a range of improvements delivered including:

• dual-lane roundabouts at Nicholson and Kargotich Road;
• dual carriageway between Kwinana Freeway and Bombay Boulevard;
• construction of a roundabout at Bombay Boulevard and a four-metre-wide pedestrian and cyclist path with lighting;
• additional street lighting between Bombay Boulevard and Kargotich Road;
• added safety measures between Kwinana Freeway and Cumming Road including shoulder widening, new line markings, raised reflectors and resurfacing.

Additionally, a new traffic bridge over the rail line is being delivered as part of the Byford Rail Extension project, removing a level crossing and significantly improving road safety in the area.

Further upgrades are planned for the road through the Tonkin Highway Extension, which is expected to commence construction next year.
