Two of the four TBMs digging the Melbourne Metro Tunnel have reached their final destination in Melbourne’s CBD.  

TBM Millie travelled from the Anzac Station site and under the Yarra River to reach the CBD, completing her 9km tunnelling journey at Town Hall Station, 25 m beneath Swanston Street, on the Metro Tunnel Project. She was the first of our TBMs to arrive.  

TBM Joan arrived soon after, coming from the State Library Station site in the west.   

TBMs Alice and Meg will complete their final sections of the Metro Tunnel's twin 9km tunnels in coming weeks. This significant milestone will mark the completion of all TBM digging works for the project.  

After all the TBMs have arrived at Town Hall Station they will be dismantled and removed from the site. Roadheaders will then continue digging the rail platform tunnels within the station box. Click here and au/32 for the tunnelbuilder archive and also visit https://metrotunnel.vic.gov.au/. 14/21 .
