Great Eastern Highway Safety Upgrade

Bilgoman Road to Mann Street



We are undertaking a major safety upgrade of Great Eastern Highway, from Bilgoman Road to Mann Street in Mundaring.

The project is jointly funded with $24 million from the Australian and Western Australian Governments and supported by the Shire of Mundaring.  Construction will be completed in two stages to allow for complex service relocations and additional planning.

Stage 1: 2 km between Kintore Road and Mann Street

Western Power has almost completed a program of works to replace its overhead power lines with an underground service, and relocate some street lighting. A construction contract has been awarded to Downer Group and work will start in late January.  This section will be completed by mid-2017.

Stage 2: 5.2 km between Bilgoman Road and Kintore Road

Wester Power will undertake further work in this area to replace the overhead power lines with an underground service and relocate street lighting.

Construction of stage two will be subject to additional planning and funding.


Project Scope

Planned improvements include:

  • Widening the highway to provide sealed shoulders;
  • Intersections with turning pockets;
  • Improved street lighting;
  • Sealed bus bays;
  • Separate shared use path from Mann Street to Kintore Road eastbound;
  • New road markings, advance warning signs and guide posts;
  • Traffic barriers in the verge and median; and
  • Improved driveway access.



This 7.2 km section of Great Eastern Highway was built in the 1950s and upgraded to a dual carriageway in the 1970s. It now carries about 25,000 vehicles per day and 70 per cent of this traffic is generated from within the Shire of Mundaring.
