Shovels in for West Gate Tunnel
WORK has finally begun on the West Gate Tunnel, Victoria’s alternative to the West Gate Bridge.
Workers have started clearing a site on Whitehall Street in Footscray, where they’ll dig down more than seven storeys, clearing the way for the projects two massive tunnel boring machines (TBMs).
When they’re launched in 2019, the two TBMs will tunnel towards the West Gate Freeway, moving nine metres per day and excavating enough rock and soil to fill the MCG.
As the TBM bores through the earth, it will install a concrete lining behind it – forming the walls, roof and base of the tunnel.
Another work site will be established on the other side of Somerville Road later this year, with the two sites connected by an elevated, covered conveyor belt.
The tunnel will open in 2022.
