Project Description

The project will upgrade and improve safety at selected locations on the Western Highway between Stawell and the South Australian border. The project will construct new overtaking lanes and rest areas, upgrade and strengthen existing bridges and seal local access roads and shoulders. The project will also determine the future alignment for a bypass around Horsham and install an Intelligent Transport System (ITS).


The project will increase freight efficiency, reduce transit times and improve traffic flow and safety for the 2,500 to 4,000 vehicles that are estimated to use the Western Highway between Stawell and the SA border each day.

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 $48.95 million. The Australian Government is contributing $40.40 million and the Victorian Government $8.55 million.


Construction commenced on 4 January 2010 and was completed on 29 April 2016. Planning for a bypass around Horsham is expected to be completed mid-2018.
