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.

In construction - 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 is now underway.  This section will be completed by mid-2017.

In all our construction and maintenance projects we seek to achieve balanced and sustainable outcomes for the community, and this is documented in our Environmental Policy.

The following sustainability initiatives have been implemented on this project to minimise the amount of construction waste going to landfill:

  • Mulching all vegetation that is cleared and re-using it on site.
  • Crushing and recycling all concrete kerbs and paths for use on other projects.
  • Recycling asphalt for hardstands and driveways.
  • Re-using all soil and pavement material that is excavated as part of the earthworks.

In development - Stage 2: 5.2 km between Bilgoman Road and Kintore Road

Taking into account community and stakeholder feedback, and the outcomes of an independent Road Safety Audit, the Stage 2 design has now been finalised. Construction is subject to additional funding.

Western Power will also be undertaking further undergrounding and relocation works in this area upgrade the existing overhead power facilities and street lighting.
