Project Description

The project will duplicate the highway between Ballarat and Stawell. The project will construct two additional lanes to provide a four lane dual carriageway, upgrade existing bridges and culverts, provide new rest areas and install an Intelligent Transport System (ITS). The project is being delivered in the following stages:

  • Ballarat to Beaufort
      - Section 1a Ballarat to Burrumbeet (8.1km)
      - Section 1b Burrumbeet to Trawalla (23.5km)
      - Section 1c Trawalla to Beaufort (2.9km)
  • Beaufort to Ararat
      - Section 2a Beaufort to Buangor (21.5km)
      - Section 2b Buangor to Ararat (12.4km)
  • Ararat to Stawell (In Planning)


The project will increase capacity, reduce transit times and improve traffic flow and safety for the 5,100 to 6,400 vehicles that are estimated to use the Western Highway between Ballarat and Stawell each day. The project will also improve access for local communities and reduce driver fatigue.

Once ITS becomes fully operational, the project will also advise drivers of current or upcoming traffic conditions in the event of an emergency or accident. This will allow drivers to make informed decisions about their intended route and reduce the need for lengthy delays or detours.


The estimated cost of the project is $659.74 million. The Australian Government is contributing $499.38 million and the Victorian Government $160.36 million.


Construction commenced in March 2010 and is expected to be complete in late 2023.
