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 flow of heavy vehicles through Pinjarra is leading to increased road safety issues. With the population of the Peel region being the fastest growing regional area in WA, these issues are expected to worsen.

The project involves road upgrades to the existing Pinjarra-Williams Road and construction of a new link to South Western Highway.


The project will:

  • improve road safety and reduce congestion for all road users
  • improve freight efficiency, connectivity and travel time


The Australian Government has committed $22 million towards the project.


The project is in planning, with construction expected to be completed by mid 2026.
