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 Westen Link in October 2017.


CityLink was Transurban’s first toll road and is 100 per cent owned by Transurban. It is under concession until 2035.

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:

  • 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 tunnel under Yarraville connecting the West Gate Freeway with the Maribyrnong River
  • a new bridge over the Maribyrnong River joining an elevated freeway above Footscray Road with connections to the Port of Melbourne at MacKenzie Road and Appleton Dock Road
  • major new cycling and walking paths and open space

We are delivering this project in partnership with the Victorian Government and CPB contractors John Holland Joint Venture.

We are currently working with our contractors to achieve sustainability ratings on the project from the Infrastructure Sustainability Council of Australia.

The West Gate Tunnel project, together with the Monash Freeway Upgrade and access improvements at Webb Dock, will slash congestion right across Melbourne.


Once completed the West Gate Tunnel will:

  • provide a much-needed alternative to the West Gate Bridge
  • 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. The road will open to traffic in 2022.


Transurban owns 100 per cent of this road.

CityLink Tulla Widening

CityLink connects with the Tullamarine (Tulla) Freeway and together these roads comprise the primary corridor between metropolitan Melbourne and Melbourne Airport.

CityLink carries 210,000 vehicles per day in its busiest section (between Bulla Road and Bell Street), including 107,000 daily trips to and from Melbourne Airport.

As Melbourne’s population increases city roads will become busier and, by 2031, the CityLink Tullamarine Freeway is expected to carry 235,000 more vehicles a day.

The CityLink Tulla Widening project is adding new lanes, better-connected entry and exit ramps, and other improvements to both CityLink and the Tulla Freeway.

Work completed

The project is being delivered in two sections. We (Transurban and our construction contractor, CPB Contractors) have completed all works on CityLink between Bulla Road and Power Street. We opened all new lanes ahead of schedule in October 2017. The project has been awarded an ‘Excellent As Built’ rating at completion by the Infrastructure Sustainability Council of Australia.

Work in progress

VicRoads and LendLease (its construction contractor) are managing work along the section of freeway between Melbourne Airport and Bulla Road. This work is on track to be completed in late 2018.
