Infrastructure upgrades and safer transport solutions in South East Perth.
The Denny Avenue Project was a transformative infrastructure initiative delivered under METRONET, combining four major projects in a high-density urban area with multiple stakeholders.
Delivered for the Western Australian Public Transport Authority (PTA), the project focused on improving safety, reducing congestion, and revitalising the Kelmscott town centre. By integrating the originally separate rail and road packages into a single design and construction project, the approach delivered significant cost efficiencies, streamlined processes, and reduced project risks.
Key works included relocating 900 metres of a century-old water main, removing a dangerous level crossing, and constructing a rail-over-bridge underpass. The project also involved redeveloping the Station Master’s House and Station Plaza, realigning the railway, building sections of the Principal Shared Path (PSP), and implementing associated rehabilitation works.
By trialling innovative construction techniques, the team enhanced safety, sustainability, and efficiency while minimising disruption to the local community. This collaborative, solutions-focused approach delivered a high-quality outcome and set new benchmarks for urban infrastructure projects.
From the outset, the project team prioritised community engagement, First Nations participation, and commercial success, delivering a project that ensured safety, positive stakeholder outcomes, and lasting benefits for the Kelmscott community.
Scope
The project scope included extension road and rail upgrades:
- Realigned the railway, constructed an underpass bridge, and removed the Denny Avenue level crossing and associated signalised intersections.
- Created a Principal Shared Path over the new Davis Road underpass on the Railway Avenue side of the rail line.
- Installed new signalised intersections along Davis Road at Albany Highway, Streich Avenue and Railway Avenue.
