Metro tunnel in Australia have reached another major milestone, with tunnel boring machines (TBM) Millie and Alice now both on their way to South Yarra.

The green TBM Alice, named after wartime medical hero Alice Appleford, has now begun her first journey – tunnelling from the site of the new Anzac Station to the Metro Tunnel’s eastern entrance in South Yarra. Alice joins the yellow TBM Millie who got a head start on the new 1.7km tunnel in April.

With TBM Joan now digging towards Parkville, and TBM Meg joining her in the coming weeks, all four TBMs will soon be digging around 20 metres deep under the city to create the tunnels for Victoria’s biggest ever public transport infrastructure project.
