The CityLink Tulla Widening project will increase capacity, reduce travel times and improve safety on CityLink and the Tullamarine Freeway.

It is making significant upgrades across 24 km from Melbourne Airport to Power Street:

  • adding an extra lane in each direction
  • upgrading the intersections at Flemington Road, Bell Street, English Street and Mickleham Road
  • creation of dedicated lanes to Bell Street from the Calder and Tullamarine Freeways
  • a new freeway management system to help manage congestion and incidents.

The project is jointly funded by the federal government, the Victorian state government and Transurban (CityLink's operator).

VicRoads and Lendlease are delivering the Melbourne Airport to Bulla Road section. Transurban and CPB Contractors are delivering the Bulla Road to Power Street section.

The project will be completed in 2018.

Why the upgrade is needed

Melbourne is continuing to grow:

  • The city's population will rise from 4.3m to 7.7m by 2051.
  • The number of passengers using Melbourne Airport will double by 2033.
  • The volume of freight handled by Melbourne's container ports will increase by 270% by 2030.

This all generates more traffic on Victoria's road network. An extra 25,000 vehicles will be using the CityLink-Tullamarine Freeway every day by 2031. The freeway and connecting roads cannot meet this increasing demand. Heavy congestion in peak periods already causes delays and accidents.

What are the benefits?

The upgrades bring direct benefits to Tullamarine Freeway and CityLink users. They also benefit local residents by improving conditions on connecting roads:

  • A 30 per cent increase in capacity, reduces congestion and allows for future growth.
  • A reduction of up to 17 minutes in peak time, makes trips between the airport and the city quicker and more reliable.
  • 3,000 fewer heavy commercial vehicles using local roads, improves conditions on local roads.
  • A reduction in casualty crashes of up to 20 per cent, benefits everyone.

How we are widening the road

We will be adding extra traffic lanes by making smarter use of the existing road corridor:

  • widening the road where space allows
  • converting emergency lanes to normal traffic lanes
  • narrowing existing lanes (this will impact on speed limits)
  • constructing emergency bays at regular intervals.

We are also integrating a new freeway management system. This helps us free up the valuable space in the emergency lanes. Overhead signs allow us to direct traffic around any incidents. Improved CCTV and incident detection means that we can respond to incidents faster.

Making major interchanges safer and more efficient

We are also using this opportunity to improve several major interchanges on CityLink and the Tullamarine Freeway. These upgrades will make the interchanges safer by reducing congestion, weaving and merging.

We are also building a separated road from both the Calder and Tullamarine Freeways to Bell Street.
