West Gate Tunnel Project tunnel road decks almost complete

Construction on the internal road surface on twin tunnels on the West Gate Tunnel Project nears completion. The removal of both tunnel boring machines (TBM) has also started.

Now more than 70 per cent complete, 4.5km of road deck has been installed across both tunnels, with a specialist machine lifting and installing more than 2000 giant 24t concrete segments to create the future road surface.

The removal of both TBM is also underway, with a 400-tonne crane moving into position to lift the final pieces of TBM Bella’s 15m wide cutterhead out of the outbound portal, and the dismantling of TBM Vida nearing completion.

This is the first Australian tunnel to be constructed with an elevated road surface, providing another tunnel under-neath to serve as an important point for maintenance of critical services, ventilation and emergency access.

The West Gate Tunnel’s twin tunnels is set to have capacity for thousands of vehicles per day across three lanes of traffic.

Important pieces of the project are coming together, with widening works on the West Gate Freeway nearing completion and the giant launching gantry crane above Footscray Road preparing for its final lifts.

Work is also underway to construct the tunnel entries and exits and prepare for the installation of the timber net structures.
