The CityLink-Tulla corridor is one of the most heavily used roads in Melbourne, carrying 210,000 vehicles per day in its busiest section.
In April 2014, Transurban reached an in-principle agreement with the Victorian Government to widen this corridor to improve traffic flow.
A minimum of one extra lane will be added to each side of the freeway between the Bolte Bridge and Melrose Drive on the Tullamarine Freeway. The project will also separate city-bound and Burnley Tunnel-bound traffic to help alleviate congestion on the West Gate Freeway.
The project’s other benefits1 include:
A 30 per cent increase in capacity, meaning reduced congestion for existing freeway users and room for future growth
Travel time savings of up to 16 minutes per trip between Melbourne Airport and the West Gate Freeway during peak periods
A reduction in commercial vehicles using local roads given that 3,000 more of them will be able to access the freeway (with 2,300 expected to be heavy vehicles), and
A decrease in casualty crashes of up to 20 per cent.
Major construction is expected to begin mid-late 2015 and completed in 2018. The project will also be integrated with the East West Link stage one project.
