Cross River Rail

As Brisbane’s population swells to more than two and a half million, this project, Cross River Rail, will help to unlock a bottleneck at the core of the city’s transport network and transform the way the public travels across South East Queensland (SEQ).

The Cross River Rail is a new 10.2 kilometre rail line from Dutton Park to Bowen Hills, which includes nearly six kilometres of twin tunnels under the Brisbane River and central business district.

The current rail network is nearing capacity and is constrained by a single river crossing and four inner-city stations, which causes the bottleneck and limits the ability to run more trains. The Cross River Rail unlocks this bottleneck by delivering a second river crossing, allowing more trains to run, more frequently, as well as integrating with new roads and bus services, to enable a ‘turn-up-and-go’ public transport system across SEQ.

BG&E undertook proof engineering of the structural, durability, geotechnical (using specialist sub-consultants) and tunnelling engineering services for the Cross River Rail.

This transformational project is providing thousands of jobs across the region and is helping to activate increasing urban development.
