Western Distributor Tunnel

The Western Distributor will provide an alternative to the West Gate Bridge, a second river crossing, and direct access to the Port. It will slash congestion, improve productivity, reduce travel times, take trucks out of the inner west, and create 5,600 jobs.


In March 2015 the Victorian Government received a market-led proposal for the Western Distributor from Transurban, operator of CityLink.

The Government has assessed the proposal and prepared a separate business case which shows the project stacks up. The business case has been submitted to Infrastructure Australia and the Federal Government for assessment. The business case has been publicly released and the Government is partnering with Transurban to build the Western Distributor.
