West Gate Tunnel Project

About the project

The West Gate Tunnel, originally called the Western Distributor, is a proposed toll road that will link the West Gate Freeway at Yarraville with CityLink at Docklands via a tunnel beneath Yarraville. It aims to relieve congestion on the M1, provide an alternative river crossing to the West Gate Bridge and move trucks away from inner west homes. Major construction commenced in early 2018 following the Minister for Planning's approval of the Environmental Effects Statement (EES) and will be completed in 2022. 

The project will include:

  • an upgrade and widening of the West Gate Freeway by two lanes in each direction between Williamstown Road and M80 interchange
  • a 1.5 km-long, six-lane tunnel
  • a new bridge over the Maribyrnong River with twin viaducts above Footscray Road and connections to the Port of Melbourne, CityLink, Dynon Road and extension of Wurundjeri Way to Dynon Road
  • over 14km of new and upgraded cycling and walking paths - including a 2.5km veloway above Footscray Road
  • improved pedestrian and cycling connections between communities along the West Gate Freeway
  • nearly 9 ha of new community open space including parkland and wetlands and more than 17,000 trees planted

Latest news

The following news items come from the state government's West Gate Tunnel Project team.

Pedestrian overpasses lifted into place

The main pieces of two brand new pedestrian overpasses along the West Gate Freeway have now been lifted into place. While the freeway was closed, crews lifted and installed the structures at Muir Street and Rosala Avenue a few weeks ago. The new and improved pedestrian overpasses will be wider, to allow pedestrians and cyclists to comfortably share the space, and include improved safety features such as CCTV, lighting and higher barriers as well as all abilities accessible ramps. The overpasses will undergo further fit-out and installation works before opening to the public. Watch the video of the bridges being lifted into place here.

Wrapping up spring works

After six weeks of roadworks the Millers Road / West Gate Freeway interchange re-opened to traffic. Crews reconstructed the Millers Road inbound entry and exit ramps, which now have wider turning lanes, and installed new storm water drainage at the Millers Road interchange, in preparation to widen the area to allow better traffic flow.

Freeway traffic switch complete

A significant milestone in widening the West Gate Freeway from eight to 12 lanes has been reached, following the completion of 10 weeks of works to move traffic onto brand new lanes. Around 10 kilometres of traffic lanes have now been shifted from the centre of the freeway to newly constructed lanes on the outer edges, allowing crews to setup new worksites in the middle. During this time crews:

  • repositioned about 8km of temporary traffic barriers and marked 10km of lines
  • installed 760 precast barriers
  • laid 55,000 metres squared of pavement and 42,000 tonnes of asphalt    


Air Pollution Report

An Inner West Air Quality Community Reference Group (CRG), established by the Victorian Government to investigate air pollution in Melbourne’s inner west, has made public its report.

The report – Air Pollution in Melbourne’s Inner West – Taking direct action to reduce our community’s exposure(PDF, 7MB) – makes 26 recommendations with 65 supporting actions. These are designed to:

  • reduce air pollution from road transport and industry (including the West Gate Tunnel Project)
  • improve the planning framework, government regulation and policy, air quality monitoring and community education

Hyde Street ramps 

As part of the West Gate Tunnel Project, works will soon begin building two new ramps for the West Gate Freeway. The new ramps will connect trucks directly to local industry and get them off local roads. The ramp on the northern side of the freeway will provide a new exit ramp for inbound traffic from the West Gate Freeway to a new signalised intersection at Hyde Street. 

The ramp on the southern side of the freeway will provide a new entry ramp for westbound traffic from a new intersection at Simcock Avenue and Stephen Street through to the West Gate Freeway.  To find out more about this part of the project click here to view the works notification from the West Gate Tunnel Project.(PDF, 412KB)

Installation of new noise walls

The West Gate Tunnel Project team will install new, high quality permanent noise walls on Fogarty Avenue between Wembley Avenue and The Boulevard. The new noise wall will be between eight and nine metres high and will be made of textured concrete panels with pale blue and green coloured acrylic panels at the top in some sections.

  • Detour via existing footpath on the east side of Grieve Parade


The $6.7 billion project was proposed by Transurban in 2014.

The Victorian Government announced in December 2015 it would proceed with the project with planning approval granted in late 2017.

Environmental Effects Statement (EES)

The EES for the West Gate Tunnel Project looked at the potential effects of the design, its construction and operation and allowed the community to voice their concerns.

Formal submissions were invited from the community during a six week consultative period which closed in July 2017.

The EES was managed by Victorian Government's Department of Environment, Land, Water and Planning (DELWP) and assessed 17 areas including but not limited to transport, air quality, noise, landscape and visual amenity, vibration, business, ecology, social and human health.

Members of the public interested in learning more about the EES can view the West Gate Tunnel EES documentation.

Amendment Summary

This Planning Scheme Amendment was prepared by the Minister for Planning, who is the planning authority for this amendment.

The amendment was made at the request of Western Distributor Authority (WDA), an administrative office within the Department of Economic Development, Jobs, Transport and Resources (DEDJTR), to facilitate the delivery of the West Gate Tunnel Project.

The Amendment came into operation on 7 December 2017, when a notice was published in the Government Gazette. The amendment changes the planning scheme to amend the schedules to Clause 52.03 and Clause 81.01 to insert a new incorporated document titled West Gate Tunnel Project Incorporated Document, December 2017.

The amendment changes the Hobsons Bay Planning Scheme to:

  • amend the Schedule to Clause 61.01 to make the Minister for Planning the responsible authority for the administration and enforcement of provisions of the planning schemes as they apply to the use and development of land for the project
  • apply the Design and Development Overlay to land in Hobsons Bay that is above and adjacent to project infrastructure to ensure new development does not compromise the structural integrity or operation of that infrastructure
  • insert Schedule 15 to the Design and Development Overlay (DDO15) and Schedule 16 to the Design and Development Overlay (DDO16)
  • amend the Schedule to Clause 66.04 to make the Secretary to the Department of Economic Development, Jobs, Transport and Resources (and the Roads Corporation from 31 December 2026) the determining referral authority for applications under DDO15 and DDO16

A copy of the Amendment can be inspected, free of charge, at the Department of Environment, Land, Water and Planning website.
