Tracking our TBMs
Cross River Rail’s twin tunnels are now fully excavated, with both of the project’s two massive Tunnel Boring Machines having completed their journey below the Brisbane River and CBD.
You can chart the journeys made by our two TBMs – Else and Merle – on the map below, as they tunnelled from Woolloongabba to Albert Street, before continuing to Roma Street and emerging at the project’s northern portal at Normanby.
Two roadheaders, that tunnelled south from Woolloongabba, have also completed their excavation having broken through into the Boggo Road station cavern.
You can find out more about all things tunnelling on our ‘Guide to tunelling page’.
Our TBMs were named after two awesome women who were groundbreakers in their own right, here in Queensland. Our roadheaders didn’t have names but were equally awesome! You can read more by clicking the links below.
