Woolloongabba station construction update
This month, it’s all about breakthroughs. The roadheaders have successfully broken through at the Boggo Road station worksite, marking completion of mined tunnel excavation south from Woolloongabba. The Tunnel Boring Machines (TBMs) Else and Merle will breakthrough at the Northern Tunnel Portal later this year, completing bored tunnelling for the project.

Haulage at Woolloongabba
Cross River Rail proposes that in the event a COVID19 public health direction is announced for the Brisbane local government area or Brisbane central business district, the morning and afternoon peak haulage restrictions be relaxed at the Woolloongabba worksite.
If you have any comments or concerns relating to this proposed change please contact the project team on 1800 010 875 or [email protected].
Additional notification will be provided prior to commencing haulage or deliveries at these proposed hours.
