Project Description

The Kwinana and Mitchell Freeways form the vital arteries in the Perth metropolitan road network. The Freeways are currently known for unreliable traffic performance, which negatively affects Perth’s productivity. As the city continues to develop, demand has outstripped the capacity of the freeway system, highlighting the need to manage the flow of people onto, through, and out of the freeway corridor to optimise its performance.

The project will roll out the next section of widening and implementation of an Intelligent Transport System (ITS) on this primary freight network which will allow for rapid monitoring and control of traffic flows. This project builds on the Australian Government’s existing commitment to widen and implement ITS between the Canning Highway and Narrows Bridge, which is currently underway.

Projects will be determined in consultation with the WA Government and will include:

  • co-ordinated ramp signalling on freeway entry ramps
  • additional lanes
  • intelligent Transport System (e.g. variable message signs)


The project will:

  • improve network connectivity, accessibility and road safety for all road users
  • improve freight productivity and alleviate traffic pressure on the existing road network


The Australian Government has committed $50 million towards the project.


The project is in planning.
