The Cross River Rail (CRR) project creates a major increase in public transport capacity for Brisbane with 17.1 km of rail corridor upgrades from Salisbury to Albion and a second rail crossing of the Brisbane River.

The project includes a new rail line from Dutton Park to Bowen Hills with a 5.9km section of twin tunnels under the river along with four new underground stations at Boggo Road, Woolloongabba, Albert Street, and Roma Street. Upgrades are also being carried out at eight existing above-ground stations Salisbury, Rocklea, Moorooka, Yeerongpilly, Yeronga, Fairfield, Dutton Park, and Exhibition.

The project resolves a critical mobility bottleneck for both Brisbane and the wider Southeast Queensland region. It is a crucial element in meeting the long-term infrastructure needs of the state’s rapidly growing population and preparation for the Brisbane 2032 Olympic and Paralympic Games. Integration with road and bus services will enable a turn-up-and-go transport system for the whole of Southeast Queensland.

AECOM has been involved with the CRR project for longer than any other technical consultant through multiple stages of the project life cycle – from initial conception through to current-day delivery. Our first engagement was contributing to the original comprehensive option generation, selection, and definition phase for the Department of Transport and Main Roads (2007-2009). Our second engagement was for the full Business Case, the Environmental Impact Statement and community consultation phases of all engineering and design activities (2010-2012).

In 2017, AECOM completed the winning tender design services for both the below ground Tunnel Stations and Development (TSD) works and above ground Rail, Integration System (RIS) sections of CRR. That same year, we were selected as the Technical Consultant as part of CPB Contractor Consortium’s UNITY Alliance Partnership to deliver the RIS package. The RIS Alliance is delivering accessibility upgrades to seven suburban stations on Brisbane’s southside from Fairfield to Salisbury, all surface rail infrastructure works on the north side of the underground section including Exhibition station, and a major redevelopment of the existing Queensland Rail Mayne Yard maintenance facility. Rail systems, including European Train Control System (ETCS) signalling and associated control systems, form part of the RIS Alliance scope as well as design, supply, and installation of the supporting rail system, and integration of the CRR project into Queensland Rail’s wider train network.

By addressing multiple aspects of the design concurrently, we have facilitated the use of highly efficient and innovative modular construction techniques for multiple elements including structural engineering, electrical, and mechanical systems.

We continue our long history on CRR and are proud to be contributing to various stages of delivery to ensure Southeast Queensland’s biggest public transport infrastructure helps improve quality of life, grow our economy, generate jobs and active urban development across the whole region.
