Tonkin Highway Extension

Thomas Road to South Western Highway

Planning is underway to extend Tonkin Highway to South Western Highway. That's an extra 14 kilometres!
Tonkin Highway <em>Extension</em>

We are extending Tonkin Highway – creating a high standard north-south transport link in Perth’s eastern corridor.

A reservation for the road extension has been included in the Metropolitan Region Scheme (MRS) for a number of years.

Preliminary concept

The project proposes to extend the highway from Thomas Road, Oakford to South Western Highway, south-east of Mundijong.

The preliminary concept includes:
  • approximately 14 kilometres of four lane dual carriageway;
  • construction and/or upgrades of intersections at Thomas Road, Orton Road, Bishop Road, Mundijong Road and South Western Highway;
  • bridges over the existing freight rail line and Perth to Bunbury rail line;
  • a shared path along the eastern side of the corridor, with planned connections to local path networks; and
  • an equine rider and pedestrian underpass under Tonkin Highway at Abernethy Road.
