Works are well underway to widen the West Gate Freeway, adding four extra lanes.
At the Williamstown Road intersection, the ground is being prepared to build the southern inbound tunnel portal, where motorists will enter the city-bound tunnel.
At the West Gate Tunnel’s northern portal work site in Yarraville, the biggest tunnel boring machines in the southern hemisphere are currently being assembled here.
Huge green gantry cranes will lower these 15.6 metre diameter and 90 metre long machines into the ground. The tunnel boring machines will dig under Yarraville and join up with the newly widened West Gate Freeway.
