Great Eastern Highway Safety Upgrade

  • Upgrading a 7.2 km section of Great Eastern Highway in two sections
  • Stage 1 between Kintore Road and Mann Street was completed in 2017. Stage 2 between Bilgoman Road and Kintore Road is set for completion by the middle of the year
  • Improve safety and efficiency; enhance pedestrian and cycling facilities


Stage 2 work includes:

  • 5.2 km of widening to provide sealed shoulders
  • 4.5 km of new drainage
  • New or extended turning pockets at all intersections 
  • New street lighting to Australian standards
  • New shared paths linking new sealed bus bays
  • New road markings, advance warning signs and guide posts
  • 11 km of 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.

Project Update

Street Lighting

Western Power will be installing street lighting to complement the project between May and September. This involves underground cabling, using trenching or directional drilling, and the installation of street light poles.

It will take some time for all the lights and cabling to be installed and commissioned. We expect all street lights to be fully operational by the end of September.

Intersection changes at Great Eastern Highway-Park and Hardey roads

Changes are being made at the intersection of Great Eastern Highway with Park and Hardey roads. From June, road users will only be able to turn left onto the highway from Park or Hardey roads and dedicated U-turn facilities will be provided approximately 260 m along the highway.

See modified layout below


Traffic Management

To protect road users and workers, the posted speed limit has been reduced to a maximum of 60 km/h on Great Eastern Highway between Bilgoman and Kintore roads. This will remain in place for the duration of the works.

Road users should also expect reductions to 40 km/h to allow for various construction activities, as well as lane closures and occasional side street intersection closures for drainage works, with signed detours in place.

Please expect occasional delays and follow all roadworks signage.

Working hours

General working hours are Monday to Saturday, 7am to 7pm. Some work, including traffic management set up, may be conducted outside these hours, subject to approval by the Shire of Mundaring. Every effort will be made to minimise disruption to residents living close to the work site. This includes dust suppression and full reinstatement of roads and verges.


Asphalting works

The following asphalting works are scheduled for June, with dates are subject to change due to weather.

12 to 14 June - Great Eastern Highway eastbound, before Park Road West just before Hardey Road and Park Road East.

  • McGlew Road closed at intersection
  • Hardey Road and Park Road East remain open
  • Access to Glen Forrest Shopping Centre maintained

14 to 17 June - Great Eastern Highway westbound (left lane), Robinson Road after Swan Road

  • Homestead Road closed at intersection
  • Swan Road closed at intersection
  • Bus stop closed

17 to 19 June - Great Eastern Highway westbound (right lane), Robinson Road after Swan Road

  • No access to Homestead Road via the median crossing (left-in & left-out only)

19 to 21 June - Great Eastern Highway westbound (left lane), Swan Road before Marri Road

  • Brooking Road south closed at intersection
  • Two bus stops closed

21 to 23 June - Great Eastern Highway westbound (right lane), Swan Road before Marri Road

  • No access to Brooking Road south via the median crossing (left-in & left-out only)

We completed a biological survey for the site and refined the Stage 2 design several times to minimise the impact of clearing.

Some of the ways we are preserving vegetation include:

  • 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 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 will be preserved
  • locating street lights within the verge, where practical, to avoid additional clearing in the median. Where this is not possible, double outreach poles are proposed in the median to keep clearing to a minimum.

In accordance with our environmental processes, the clearing extents for this project were also reviewed by the Shire of Mundaring and the Department of Biodiversity, Conservation and Attractions.

All vegetation cleared for this project will continue to be mulched and re-used on-site. A replanting program featuring local species is being delivered for Stage 1 in consultation with the Shire of Mundaring. Further replanting will be undertaken in mid-2019 to complete Stage 2 works.

We will also recycle concrete kerbs, paths and asphalt.


Stage 2:

  • September 2018: Construction starts
  • May 2019 to September 2019: Lighting (Western Power)
  • Mid-2019: Revegetation

  • Enhance pedestrian and cycling facilities


The project is jointly funded, with $34 million from the Australian and Western Australian Governments and supported by the Shire of Mundaring.
