We operate CityLink in Melbourne and we have one major project on the go: the West Gate Tunnel.


CityLink is a 22 kilometre road. Most of the road is eight lanes wide, with four inbound and four outbound lanes.

The Bolte Bridge and the Burnley and Domain tunnels are all part of CityLink.

CityLink connects Melbourne's Monash, West Gate, and Tullamarine freeways. It also connects the city centre with Melbourne’s major airport and port.

Completion date

CityLink opened in two stages: Western Link in August 1999 and Southern Link in December 2000.

We completed an upgrade of Southern Link in 2010 and Western Link in October 2017.


CityLink was Transurban’s first toll road and is 100 per cent owned by Transurban. It is under concession until 2045.

Burnley Tunnel Upgrade Project 

In June 2022, works to revitalise one of Melbourne’s busiest transport links, the 3.4km Burnley Tunnel, commenced.

In March 2023, the Burnley Tunnel’s  state-of-the-art pacemaker lighting was switched on to help drivers maintain a consistent speed in the tunnel. We also repainted the tunnel walls, repaired barriers and transformed the lighting along the tunnel walls with brighter, more energy efficient LEDs.

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:

  • 6.8 kilometres of new tunnel between the West Gate Freeway and the Maribyrnong River
  • 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 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 working with our contractors to achieve sustainability ratings on the project from the Infrastructure Sustainability Council of Australia.


Once completed the West Gate Tunnel will:

  • 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.


Transurban owns 100 per cent of this road.
