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 - May 2022

The Tunnel Boring Machines (TBMs) have now been taken away from site, allowing the gantry crane to be removed as well. Construction can also start on the final section of the portal roof that was kept open to extract the TBM components. Delivery of railway tracks for the twin tunnels has begun and rail will start to be transferred into the tunnel later this month. Excavation and construction of the Northern Tunnel Portal structure is ongoing.

Temporary pedestrian bridge closures

Temporary pedestrian bridge closures

Cross River Rail’s twin tunnels are being constructed beneath the pedestrian bridge that spans the rail corridor and the Inner City Bypass. Between 6:30pm and 6:30am on Friday 14 January 2022, a temporary pedestrian detour will be in place for up to one week while tunnelling occurs beneath the bridge.

Location of site access changes at Victoria Park.

Victoria Park – Site access changes

From late August, changes will be made to the existing Northern Tunnel Portal site access at Victoria Park to prepare for removal of the Tunnel Boring Machines (TBMs) with oversized vehicles.

An underground sewer main located under the rail corridor at Normanby and within Victoria Park will be relocated approximately 300 metres east. Construction access will be via existing footpaths and access roads in Victoria Park.

Northern Tunnel Portal - Sewer main relocation

From December 2020 for approximately four months, an underground sewer main located under the rail corridor at Normanby and within Victoria Park will be relocated approximately 300 metres east to enable construction of the Cross River Rail Northern Portal.
