Upgrading CityLink from the West Gate Freeway to Melbourne Airport on the Tullamarine Freeway will increase the road's capacity by up to 30%.

Project overview

The CityLink Tulla Widening project involves adding new lanes and other measures to improve traffic flow across 24 kilometres of freeway between the CityLink tunnels and Melbourne Airport. The project will provide significant travel time savings between Melbourne Airport and Power Street during peak periods. The project will be delivered in two sections:

  • Melbourne Airport to Bulla Road (managed by VicRoads)
  • Bulla Road to Power Street (managed by Transurban)

Project benefits

The CityLink Tulla Widening project will reduce congestion and improve safety. It will include:

  • At least one extra lane in each direction from Melbourne Airport to the West Gate Freeway, including extra lanes on the Bolte Bridge
  • A new lane on the West Gate Freeway (eastbound) between Bolte Bridge and Power Street
  • Improvements to the Flemington Road/Mt Alexander Road interchange
  • Construction of a new Bell Street to Pascoe Vale Road connection, including a new bridge over CityLink and the Craigieburn train line
  • Two new dedicated lanes to Bell Street, from the Tullamarine Freeway and Calder Freeway
  • A new dedicated lane from the Tullamarine Freeway and Mickleham Road to the Western Ring Road

Benefits will include:

  • A 30 per cent increase in capacity, reducing congestion
  • Travel time savings between Melbourne Airport and the West Gate Freeway during peak periods
  • A reduction in commercial vehicles using local roads, as 3,000 more commercial vehicles will be able to access the freeway (2,300 of which will be heavy vehicles)
  • A reduction in casualty crashes of up to 20 per cent

Freeway Management System

A freeway management system will also be introduced, and will include:

  • Lane use management signs to manage which lanes are open
  • Variable speed limit signs above all lanes
  • Ramp signaling: stop and go traffic lights to improve traffic flow and reduce congestion as traffic enters the freeway from on-ramps
  • CCTV cameras: to monitor for incidents, help response times and minimise disruptions
  • Travel time information signs so people can plan their journey
  • Electronic message signs: to notify road users of planned changes or disruptions
  • Automatic incident detection system: to alert us to incidents in real time.

Timing and construction

CPB Contractors is delivering works on CityLink between Bulla Road and Power Street. These works commenced in October 2015 and are expected to be completed in early 2018.

Sections of the project will be opened progressively when it is safe to do so ensuring motorists get the benefits as soon as possible. During construction, disruptions to traffic will be minimised with most work taking place outside of peak periods.

Residents and motorists will be notified in advance of any impacts and works will be communicated on the project website www.citylinktullawidening.vic.gov.au
