Tracking our TBMs

Our two Tunnel Boring Machines – Else and Merle – have now been launched.

You can check out their progress on our map below as they make their way from Woolloongabba to Albert Street, before continuing to Roma Street and finally emerging at the project’s northern portal at Normanby.

Two roadheaders will also dig twin tunnels south from Woolloongabba to Boggo Road.

You can find out more about all things tunnelling on our ‘Guide to tunelling page’.

Our TBMs are named after two awesome women who were groundbreakers in their own right, here in Queensland. Our roadheaders don’t have names but are equally awesome! You can read more by clicking the links below.
