As one of Australia's largest intermodal freight precincts continued to grow, Transport for NSW identified the need for a more efficient and reliable connection to Moorebank Logistics Park. They developed the Cambridge Avenue Upgrade project to improve freight and commuter access, reduce pressure on the M5 corridor, and support long-term growth across south-west Sydney. Transport for NSW engaged our team to deliver the concept design and Review of Environmental Factors (REF) report for the project.
The project involved upgrades to Cambridge Avenue, Campbelltown Road, and Camden Valley Way, including new signalised intersections, motorway ramp connections to the M31 Hume Motorway and bridge structures over rail, and integrated active transport infrastructure. Working within a highly constrained corridor, our multidisciplinary team undertook extensive investigations, including utility, geotechnical, environmental, ecological, and cultural heritage assessments, to inform design development and approvals.
Close collaboration with Transport for NSW, Sydney Trains, ARTC, Transurban, utility providers, developers, and government agencies was critical to project success. We managed complex interfaces with rail infrastructure, motorway networks, major utilities and future developments while maintaining constructability and supporting long-term network performance.
Environmental considerations were a key focus throughout the project. Design refinements helped avoid impacts to sensitive Cumberland Plain Woodland, while drainage, flood resilience, and active transport outcomes played key roles in the broader corridor strategy. We also incorporated future traffic growth modelling and other requirements to support a flexible and sustainable transport solution.
The completed concept design and environmental assessment will allow Transport for NSW to establish a future-ready corridor that improves access to Moorebank Logistics Park, supports regional growth, enhances freight efficiency, and provides a strong foundation for future project delivery.
