Construction of a tunnelling hub at Yarraville in Melbourne marks a key milestone in the construction of the West Gate Tunnel, which will provide new road links to the city’s port by 2022.
The hub will include a new shed to reduce noise and dust during processing of 1.5Mm3 of tunnelling spoil during CPB Contractors John Holland Joint Venture’s construction work.
The tunnelling hub will be connected to the neighbouring northern portal site by an elevated, covered conveyor belt that will transport spoil from the project’s two tunnel boring machines into the shed. A footbridge will also be built for workers to move between the two sites.
The tunnelling hub is the third major West Gate Tunnel worksite to be established in recent weeks, with crews already working at the neighbouring northern portal site and the widening of the West Gate Freeway.
