The first tunnel boring machine (TBM) has broken through into the future Parkville station as it excavates from Ardern Station to the State Library Station.
This is the first TBM to make it to Parkville after being launched in May, with the second TBM to make it to Parkville in the next weeks.
The TBM is now being moved through the station box. During this period the TBM will be cleaned and recommissioned before being launched towards the State Library Station.
All four TBMs are currently excavating future metro tunnels underneath Melbourne.
Victorian Minister for Transport Infrastructure Jacinta Allan thanked those working on the project for their efforts.
“It’s fantastic to see [TBM] Joan arrive at the future Parkville station. The Metro Tunnel is working through the pandemic supporting thousands of jobs, while creating the new space to run more trains more often.”
The stations themselves are also progressing, with work on the permanent structure for Parkville Station below Grattan Street taking place. Station entrances are also currently under construction.
The project is creating nearly 7,000 jobs and those currently on site are required to adhere to COVID-19 safety measures due to Victoria’s stage 4 restrictions.
“Construction of the Metro Tunnel is continuing under strict health requirements – keeping workers safe while they deliver this vital project,” said Allan.
With the 1.2-kilometre tunnels between Arden and the western tunnel entrance in Kensington completed last year and tunnelling underway from Anzac Station to the eastern tunnel entrance at South Yarra, more than 290,000 cubic metres of rock and soil have been excavated. 23,000 concrete segments have been installed to line the walls of the tunnels.
Once complete, estimated in 2025, the project increase Melbourne’s rail capacity by half a million passengers a week during the peaks.
