About this video
Acting Premier and Minister for Public Transport, Jacinta Allan, visited the project's first worksite at Domain on 22 September to announce the start of enabling works for the Metro Tunnel.
The works are part of the early works contract which was awarded to John Holland in June 2016.
Work has now started on the relocation and protection of up to 100 services under the $324 million contract, which also includes the excavation of 11-storey deep shafts next to Swanston Street to enable the construction of the two new city stations.
The station shafts, due to begin early next year, will be up to 35 metres deep and involve the excavation of 34 Olympic-sized swimming pools worth of soil and rock from beneath the city.
