On the 27/04/20 Metro Tunnel reached another major milestone with TBM Millie launching from the site of the new Anzac Station in Melbourne. Millie is digging the first tunnel between Anzac Station and the Metro Tunnel’s eastern entrance at South Yarra, with TBM Alice to follow in the coming weeks.

The components of TBMs Millie and Alice began arriving onsite in late 2019. Assembly started in January and both have undergone comprehensive commissioning and testing. Once Millie and Alice finish this phase of tunnelling later this year, they will be disassembled and returned to the Anzac Station site to commence their next journey towards the Central Business District (CBD).

Construction on Anzac Station, which will be 300 m long and sit 22 m below St Kilda Road, is continuing.

The first two TBMs Joan and Meg broke through at Kensington in February and are currently being reassembled at Arden Station where they will later begin their 1.8km journey to Parkville Station.

Lots of progress is happening across all sites, with the excavation of the station box at Parkville completed in April. Three roadheaders are excavating deep under Swanston and Flinders streets to construct the central cavern of Town Hall Station, and tunnelling of the twin tunnels in the CBD – at the site of the new State Library Station – will get underway mid-year.
