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. Major works for Stage 2, between Bilgoman Road and Kintore Road, are set for completion in September 2019 
  • Improve safety and efficiency; enhance pedestrian and cycling facilities

Overview

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 until 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 have been made at the intersection of Great Eastern Highway with Park and Hardey roads. Road users can now only turn left onto the highway from Park or Hardey roads. Dedicated U-turn facilities are provided approximately 260 m along the highway.

See modified layout below:

Traffic Management

To protect road users and workers, the posted speed limit is 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 and asphalting, 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 and asphalting, may be conducted outside these hours, subject to approval by the Shire of Mundaring. Every effort is being made to minimise disruption to residents living close to the work site. This includes dust suppression and full reinstatement of roads and verges.

Environment

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 being installed 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 has been completed for Stage 1 in consultation with the Shire of Mundaring. Further replanting will be undertaken in mid-2020 to complete Stage 2 works.

We will also recycle concrete kerbs, paths and asphalt.

Timeline

Stage 2:

  • September 2019: Major works complete
