West Gate Tunnel
The West Gate Tunnel will be a 17 kilometre road connecting Melbourne’s west with the central city. The tunnel will serve as a vital alternative to the city’s heavily congested West Gate Bridge.
Once completed, this new road, including 6.8 kilometres of tunnel, will improve connections between Melbourne’s west, the city centre, and Melbourne’s major ports.
The West Gate Tunnel project includes:
- two additional lanes in each direction on the West Gate Freeway between the M80 Ring Road and Williamstown Road
- ramps between the West Gate Freeway and Hyde Street for trucks carrying dangerous goods
- a new tunnel under Yarraville connecting the West Gate Freeway with the Maribyrnong River
- a new bridge over the Maribyrnong River joining an elevated freeway above Footscray Road with connections to the Port of Melbourne, CityLink and city north
- major new cycling and walking paths and open space
We are delivering this project in partnership with the Victorian Government and the CPB contractors John Holland Joint Venture.
We are currently working with our contractors to achieve sustainability ratings on the project from the Infrastructure Sustainability Council of Australia.
The West Gate Tunnel project, together with the Monash Freeway Upgrade and access improvements at Webb Dock, will slash congestion right across Melbourne.
Once completed the West Gate Tunnel will:
- provide a much-needed alternative to the West Gate Bridge
- reduce peak travel time by up to 20 minutes
- take around 28,000 vehicles off West Gate Bridge, 22,000 vehicles off Bolte Bridge, and remove more than 9,000 trucks from local streets a day
- create 6,000 new jobs
- offer more than 14 kilometres of new cycling and walking paths
- provide close to nine hectares of open space
- deliver stronger roads and bridges to carry heavier loads and support Victoria’s (and Australia’s) high productivity freight network
Timing and cost
This $6.7 billion project will be funded through tolls on the West Gate Tunnel, changes to the CityLink concession, and a Victorian Government contribution.
Planning approvals were granted in December 2017 and construction started in January 2018. The road will open to traffic in 2022.
Transurban owns 100 per cent of this road.
