West Gate Tunnel Project

The Victorian Government is partnering with Transurban to build the West Gate Tunnel, a vital alternative to the West Gate Bridge that will provide quicker and safer journeys, remove thousands of trucks off local streets and create 6,000 jobs.

Construction on the West Gate Tunnel will begin in 2018 with completion expected in 2022.

Along with the Monash Freeway Upgrade and Webb Dock access improvements, the West Gate Tunnel provides a transport solution that will improve traffic flow from Geelong to Pakenham.

Business case

The Victorian Government received a market-led proposal for the West Gate Tunnel Project from Transurban, operator of CityLink, in March 2015.

The government has assessed the proposal and prepared a business case which found the West Gate Tunnel Project (formerly the Western Distributor) and the Monash Freeway Upgrade will deliver value-for-money and an $11 billion boost to Victoria's economy. The conservative benefit cost ratio of 1.3 means the West Gate Tunnel Project will provide $1.30 in benefits for every $1 in costs.

The West Gate Tunnel (formerly the Western Distributor) business case is available on the  West Gate Tunnel Project publications page.
