Work begins on Melbourne Tunnel project

west gate tunnel project

Work has begun on the £3.9bn West Gate Tunnel in Melbourne. 

Workers have started clearing a site ready for seven storey shaft to be built, before two purpose-built 15.6m diameter TBMs will be launched next year.

A JV between CPB Contractors and John Holland have designed and will build the tunnel for the AUS$6.7bn (£3.9bn) scheme.

The design and construction works include a 2.8km eastbound tunnel and 4km westbound tunnel widening the West Gate Freeway from eight lanes to 12 between the M80 Ring Road; a new bridge over the Maribyrnong River; an elevated road along Footscray Road to the Port of Melbourne, CityLink and the city’s north; and major new cycling and pedestrian paths.

Jacobs Engineering with Aurecon has been selected by the JV to carry out the engineering design.

The project will use two purpose-built TBMs to build the 14.1m diameter tunnels boing nine metres a day. A precast concrete lining with cast-in Ethylene Propylene Diene gaskets will line the tunnel.

The project will be complete in 2022.
