Melbourne Metro Press Release

HUGE DIGGER AT WORK BENEATH CBD

The Metro Tunnel Project has reached another significant construction milestone, with the launch of a massive roadheader machine that has begun creating the huge underground cavern for the new State Library Station deep beneath Melbourne’s CBD.

The 118-tonne, 15-metre long machine has been lowered in pieces almost 30 metres underground into a shaft within the A’Beckett Street acoustic shed before being re-assembled ahead of digging commencing this week. It will eventually be joined at this location by a further two roadheaders.

Roadheaders are massive excavating machines fitted with a mounted cutter head that will mine out the caverns for both Metro Tunnel CBD stations - State Library and Town Hall.  A total of six roadheaders will be used in the CBD as part of the project - three for each station.

Round-the-clock excavation continues within the Franklin St East acoustic shed, with the access shaft currently at a depth of around 30 metres. Piling is currently underway to support the excavation of access shafts at Franklin Street West and on the corner of La Trobe and Swanston streets.
