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.

Northern Tunnel Portal construction update - November 2022 to January 2023

The Northern Tunnel Portal site is edging closer to achieving the key milestone of the structure being fully enclosed, as the team continues installing the final pre-cast roof segments. Construction of the topping slab and backfill of the remaining roof area will then be undertaken until early 2023.
