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.

 Lloyd Street Bridge update

Main Roads has been liaising with local stakeholders, Traditional Owners and the City of Swan to explore the viability of a new alignment for the Lloyd Street Bridge. The bridge would be relocated 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. The outcomes of a feasibility study are currently being examined by government.
