Project Description

The South Western Highway is a major freight corridor in south-west WA, which currently runs directly through the town of Pinjarra.

The project will deliver stages 1 and 2 of the Pinjarra Heavy Haulage Deviation to conctruct an alternative route for heavy vehicles to bypass Pinjarra town centre.

The project will address road safety issues relating to the flow of heavy vehicles through Pinjarra. With the population of the Peel region being the fastest growing regional area in WA, these issues are expected to worsen over time.


  • Improve road safety for all road users
  • Reduce congestion and improve travel times
  • Improve efficiency and network reliability
  • Improve freight productivity


The Australian Government has committed $200 million towards the $250 million project.


The project is in planning, with construction expected to be completed by late 2028.
