Construction on the internal road surface in the twin tunnels of the West Gate Tunnel Project in Victoria is nearing completion, with works now more than 70 per cent complete.
Over 4.5 kilometres of road deck has been installed across both tunnels. The removal of both Tunnel Boring Machines that worked on the project is also underway, with a 400 tonne crane helping to dismantle the final pieces.
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 twin tunnels will have capacity for thousands of vehicles per day across three lanes of traffic.
CPB Contractors is working with Transurban and the Victorian Government to deliver Victoria’s West Gate Tunnel Project in a joint venture.

The widening works on the West Gate Freeway are nearing completion, with the giant launching gantry crane above Footscray Road also 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.
