Melbourne Metro Rail Project – Tunnelling under the Yarra River

October 10, 2019


It is proposed that the Melbourne Metro Tunnels will be built under the Yarra River using Tunnel Boring Machines. Tunnel Boring Machines have specialised cutting heads designed to grind through soil and rock. While the front of the machine is excavating the tunnel, another part of the machine will install the tunnel lining. Once complete, the new tunnels will allow more trains to run through the CBD and across the wider network.
