Work is underway on Brisbane's new underground

With major construction now underway at all of Cross River Rail’s main station sites as well as multiple locations within in the rail corridor, our work sites are constantly evolving and changing.

Around Our Work Sites

With the implementation of appropriate social distancing measures and personal hygiene protocols at each worksite to ensure the safety of workers, work has been able to continue at all of our construction sites during the COVID-19 pandemic and we have been able to ensure continued progress of our Project.

Updates from around our worksites up to 15 October include:

Tunnelling

  • Tunnel Boring machines (tunnelling north from Woolloongabba): TBM Else has excavated more than 3,372 metres while installing 1,768 precast concrete rings, and TBM Merle has excavated more than 2,971 metres while installing 1,547 precast concrete rings. Both TBMs have relaunched from the Roma Street cavern and recommenced installing precast segments.

Celebrating two years of construction

We’ve just passed the two-year mark for construction of our Tunnels and Stations and this video produced by our major contractors is everything we love about the work crews, subbies and suppliers that are making Queensland’s biggest infrastructure project happen.
