​​Great Eastern Highway Safety Upgrade

  • Upgraded a 7.2 km section of Great Eastern Highway in two sections
  • Stage 1 between Kintore Road and Mann Street was completed in 2017. Major works for Stage 2, between Bilgoman Road and Kintore Road, was completed in late 2019.
  • Improved safety and efficiency; enhanced pedestrian and cycling facilities


This project included:

  • 7.2 km of widening to provide sealed shoulders 
  • Upgrading 23 intersections, including new or extended turning pockets 
  • New street lighting to Australian standards 
  • New concrete paths linking 29 upgraded bus stops 
  • New road markings, advance warning signs and guide posts 
  • Drainage and safety barriers
It also includes new crossovers to tie into existing driveways for residential and business properties fronting Great Eastern Highway. Written notification will be provided to residents, before this work is undertaken.


We preserved vegetation as part of this project by:

  • maintaining the current level of carriageways to avoid any unnecessary damage to underground root systems 
  • installing safety barriers on both sides of the median. While safety standards require a 1.2 m deflection zone (clear zone) behind these safety barriers to the nearest tree, in wider sections of the median at least eight to 10 metres of vegetation was preserved ​
  • locating street lights within the verge, where practical, to avoid additional clearing in the median. Where this was not possible, double outreach poles were installed in the median to keep clearing to a minimum.

All vegetation cleared for this project was mulched and re-used on-site. A replanting program featuring local species has been completed for Stage 1 in consultation with the Shire of Mundaring. Further replanting will be undertaken in this section and between Kintore Road and Bilgoman Road in mid-2020.

We also recycled concrete kerbs, paths and asphalt.


  • Improve safety and efficiency
  • Enhance pedestrian and cycling facilities


The project was jointly funded by the Australian and Western Australian Governments and supported by the Shire of Mundaring.​​
