Northern Tunnel Portal Construction

Cross River Rail is a new 10.2-kilometre rail line. It includes 5.9 kilometres of twin tunnels from a southern portal near Dutton Park station under the Brisbane River and the Brisbane CBD.

The northern portal is where trains will enter and exit Cross River Rail’s twin tunnels and is located in the rail corridor at Normanby.
