The Bunbury Outer Ring Road project is the biggest infrastructure project ever undertaken in the south-west and will provide new and improved access to Bunbury-Geographe and the wider south west region.

This project will see the construction of a 27 kilometre, four-lane road connecting Forrest Highway to Bussell Highway.

If you’re travelling the South West region throughout the holiday season, please be aware that traffic management, lane closures and speed reductions are in place on sections of Forrest Highway, Bussell Highway and South Western Highway. To find out more, visit the Main Roads WA website for a guide to the perfect holiday road trip.

Completed in May 2013, the four-kilometre Central Section - Boyanup Picton Road to South Western Highway, included the extension of Port Access Road (Willinge Drive).

The Northern Section - Forrest Highway to Boyanup Picton Road, will provide better access for Bunbury CBD and Ferguson Valley, with preparation works now underway.

The Southern Section - South Western Highway to Bussell Highway, will include a ‘Y’ interchanges at Bussell Highway and Centenary Road, and a connection to Jules Road.

  • Will allow drivers to avoid 13 sets of traffic lights and one rail level crossing between Forrest Highway and Bussell Highway
  • Improved safety for local residents by removing a significant number of trucks from local roads each day
  • Create free flowing traffic movements for the freight transport industry
  • Create thousands of local jobs
  • Approximately 20,000 native seedlings will be planted as part of the project's earthworks
