Citylink to Tulla road widening

The CityLink to Tulla road widening is intended to enhance the daily capacity and reduce travel times across the 24km route between the CityLink tunnels and Melbourne Airport. The two-stage construction project commenced in October 2015 and is expected to be completed by mid-2018.

The project is owned by Australia’s Victorian Government and CityLink. The construction work from Melbourne Airport to Bulla Road is being managed by VicRoads, while that from Bulla Road to Power Street is being managed by Transurban.

The CityLink Tullamarine corridor is one of the busiest most congested roads in Melbourne and currently carries approximately 210,000 vehicles. It is estimated to be used by more than 235,000 vehicles a day by 2031.

Project background and benefits

The proposal to widen the Citylink and Tullamarine Freeway was initiated in August 2015. The freeway widening work is proposed to be completed in two stages. The first stage of construction began in October 2015, followed by the second stage in May 2016.

The benefits of the freeway road widening will include enhancement of the capacity on CityLink-Tulla road by 30%. It will result in reduction of commercial vehicles using local roads, as more than 3,000 heavy and commercial vehicles will be able to use the freeway. It will also ease congestion and improve safety and will reduce the casualty crashes by 20%.

The road widening project is expected to provide direct and indirect employment opportunities for more than 1,400 people.
