The Great Eastern Highway Bypass Interchanges is being delivered by the Greater Connect Alliance, a consortium comprising Laing O’Rourke, AECOM and Arcadis, in partnership with Main Roads.

The Great Eastern Highway Bypass provides a critical connection between Roe Highway and Tonkin Highway, particularly for vehicles travelling to and from the Hazelmere and Forrestfield/High Wycombe industrial areas.

The intersections of Great Eastern Highway Bypass (GEHB) with Roe Highway, Stirling Crescent and Abernethy Road have become increasingly congested with road users experiencing significant wait times during peak periods. This increased congestion is due to the presence of heavy vehicles moving in a north-south direction between the Forrestfield/High Wycombe and Hazelmere industrial areas, and Perth hills residents and heavy vehicles seeking to avoid heavy traffic through Midland and Guildford. In addition to traffic congestion issues, future expansion of the southern part of Midland around the former railway workshops precinct is constrained by the lack of direct access to and from the south.

The $386 million project will deliver improved freight efficiency, connectivity and travel Time. It will improve access to Perth Airport, improve connectivity between major freight infrastructure hubs, and reduce costs for heavy vehicle operators, companies and commuters as a result of reduced travel time.

What is the timeline for the project?

Subject to availability of land, environmental approvals and the outcomes of detailed technical investigations, major construction is expected to commence in early 2022. Some early works such as surveying, geotechnical investigations, clearing and service relocation will commence in 2021.
