South Western Highway Realignment

& Collie River Bridges Replacement - Burekup



Our South West Region is undertaking a project to realign a 1.7km section of the South Western Highway in Burekup between Russell Road and Raymond Road. This will include the construction of a new bridge over the Collie River and a culvert over the Collie River floodway. Work commenced in September 2015 and is expected to finish in April 2016. The culvert over the Collie River floodway is almost complete.

There will be some significant changes to the road layout over January and February 2016. Road users are advised that traffic management will be in place, and we ask you to follow the directions of traffic controllers and signage for your safety. Upcoming works include:

  • January/February 2016: the tie in and new lanes at the Raymond Road and Orchard Drive intersections with the highway will be constructed.
  • March 2016: Traffic will be moved onto the new road and the old bridges will be demolished.

Funding for the project was announced in September 2015.


Project Scope

The project involves;

  1. Construction of a new bridge downstream from the existing bridge which is nearing the end of its life and needs to be replaced;
  2. Construction of a reinforced concrete box culvert to replace the existing smaller bridge over Collie River floodway;
  3. Realigning a 1.7km section of the existing road to improve geometry and tie in with the new bridge.

The new bridge will have upgraded safety barriers and the natural river bank will be enhanced with rock protection, and other modifications to improve erosion control.

Modifications to existing intersections will be required, with works including:

  • Raymond Road;
  • Russell Road;
  • Orchard Drive.


Project Benefits

The project will:

  • Provide a safer and modern road and bridge with safety barriers.
  • Cater for increasing traffic volumes, especially heavy vehicles.
  • Improve safety for locals accessing Burekup.
  • Replace the existing deteriorating bridges with modern, durable structures with a longer life span and less maintenance liability and costs.
  • Improve erosion control of the bridge and culvert structures, and protect the natural river bank using rocks.


Further Information

We will be providing information to the Shires of Dardanup and Harvey, the Burekup community, businesses, schools and other stakeholders about the project using newsletters, website information, signage, media and other channels.
