Work has begun on the West Gate Tunnel, Victoria’s long overdue 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 project’s 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.
Construction crews following behind will work to build the road surface and install electrics, ventilation and safety systems.
Another work site will be established on the other side of Somerville Road later this year, with the two sites connected by an elevated heavy-duty, covered conveyor belt.
The conveyor will transport dirt and rock from the TBM excavation to large sheds, to be loaded onto covered trucks and removed from the site.
The two sites will be home to more than 500 workers – part of 6000 jobs created on this massive project.
More project sites will be established in the inner west over the coming months as work gets underway to widen the West Gate Freeway and move utilities including gas pipes, sewers and drains to make way for the tunnel.
The West Gate Tunnel will open in 2022.
