West Gate Tunnel project

West Gate Tunnel project


The West Gate Tunnel project is a major road, tunnel and bridge project currently undertaking an environment effects statement (EES) assessment process. 

The project has three key components:

  • widening of the West Gate Freeway
  • a new road tunnel under Yarraville
  • connections to the Port of Melbourne, CityLink and the CBD.

A bridge over the Maribyrnong River will provide an alternative river crossing to the West Gate Bridge. 

The Western Distributor Authority (WDA) is responsible for the management of the project on behalf of the Victorian Government and in partnership with Transurban. This includes planning and development, stakeholder engagement, procurement, through to construction and delivery.  

EPA’s role

The West Gate Tunnel project triggers requirements for key approval applications. This includes an EPA works approval.

The project design includes a road tunnel ventilation system.  

Under the Environment Protection (Scheduled Premises and Exemptions) Regulations 2007, road tunnel ventilation systems require a works approval. 

Works approvals are issued by EPA under the Environment Protection Act 1970.

When the works approval application is received by EPA, the application will be advertised in print and on EPA’s website. The advertisement will include details for public participation, including how to make a submission on the works approval application.
