Intersection at Roe Highway and GEH Bypass

What's happening

 Early works complete; construction placed on hold

Pre-construction works associated with the Great Eastern Highway Bypass Interchanges (GEHBI) project are complete. These works include services relocations and protection works across the construction site, including Western Power, ATCO Gas, water corporation and Local Government drainage main installation.

In addition, the project team has completed the realignment and reconstruction of Arum Lily Place and the upgrade of Adelaide Street. Earthworks to form the embankments and consolidate ground conditions for the GEH Bypass and Abernethy Road interchange have also taken place in recent months.

Project designs for both major interchanges on the GEH Bypass – at Roe Highway and Abernethy Road - have also been finalised.

The project has reached a point where major construction works are ready to commence, however, further construction activity has been placed on hold while Main Roads secures the approvals required to deliver the works.

 Watermain installation works

As part of the early works program, a new watermain is being installed along Brinsmead Road and across Abernethy Road to Adelaide Street. These works will take place over consecutive weekends through a 24/7 operation. Works include trench excavation, pipe installation and backfill.  The following road closures will be in place during this period:

  • 8pm Friday, 17 March to 4am Monday, 20 March 2023
    • Brinsmead Road closed between Abernethy Road and Collopy Road
  • From 8pm Friday, 24 March to 4am Monday, 27 March 2023
    • Abernethy Road closed between Kalamunda Road and Ulm Place / Yagine Close roundabout.
  • 6am-6pm,  Sunday, 2 April 2023,
    • Brinsmead Road closed between Abernethy Road and Collopy Road.

Please allow extra journey time and follow the detour signage provided.

 Lloyd Street Bridge update

Main Roads and the City of Swan have started discussions with Traditional Owners to explore the viability of a new alignment for the Lloyd Street Bridge. A recent proposal submitted by Traditional Owners would relocate the bridge further west, to a narrower crossing of the Helena River, loosely following the footprint of the old Whiteman Road bridge that was demolished in 2002. Subject to the outcome of these discussions, further site investigation and project development activity could take place.
