New project milestones take Lloyd Street Extension a step closer to construction

Early works are getting underway on the Lloyd Street Extension project in Western Australia, taking it a step closer to construction.

Site preparation and geotechnical investigations will be carried out from mid-September to mid-October to better understand ground conditions and support the detailed design of a new bridge. In addition, weed treatment will be undertaken in areas identified for future revegetation and tree planting.

Works will take place between 7am and 6pm, Monday to Friday, with the scope to include:

• Preparing temporary access to the project site from the Lloyd Street and Stirling Crescent roundabout using an excavator
• Geotechnical investigations using a drill rig
• High-temperature steam weed treatment in future revegetation areas

Cultural heritage monitors will also be present during all ground-disturbing works.

In mid-August of this year, the Greater Connect Alliance was awarded the contract to deliver the Lloyd Street Extension project. The Alliance is comprised of Laing O’Rourke, AECOM and Arcadis, in partnership with Main Roads Western Australia (MRWA).

The contract award follows four years of extensive consultation with Traditional Owners, which resulted in an informed revised bridge design that balances cultural heritage, environmental protection and improved transport outcomes.

Over the life of the project, Greater Connect Alliance will leverage innovative design and construction approaches to deliver value for money while, at the same time, create employment, training and upskilling opportunities for Aboriginal people.

The Alliance will continue working on project design, with construction anticipated to begin later this year.

“We’re thrilled to see this important project move forward and to see the benefits this will bring to a congested road network. We deeply appreciate MRWA’s commitment to continuing this collaboration and look forward to delivering outstanding outcomes together,” Laing O’Rourke Managing Director – Australia, Mark Dimmock said.

Key features of the Lloyd Street Extension include:

• A new bridge over Helena River, connecting existing roundabouts on the northern and southern side
• Paths for pedestrians and cyclists
• Southern extension of Lloyd Street from Bushmead Road roundabout to the Great Eastern Highway Bypass and Abernethy Road
• New four-way intersection at Lloyd Street, Great Eastern Highway Bypass and Abernethy Road, with improved turning capacity for all traffic movements

The project is expected to be completed in 2028, and it will improve connectivity, reduce congestion and boost safety on the approach to Midland from the south while also providing improved access to the Hazelmere Industrial area, Midland Health Precinct, Curtin University’s Midland campus, commercial centres and surrounding residential areas.
