Melbourne is continuing to grow at a rapid pace, with the population expected to rise to 7.7 million by 2051. With passengers travelling to Melbourne Airport expected to double by 2033, and freight handled by Melbourne ports to increase by 270% by 2030, an additional 25 000 vehicles are expected to use the CityLink-Tullamarine freeway by this time.
To cater for this growth, and to combat an already heavily congested road network, the CityLink Tulla Widening project will ultimately increase the capacity of the road by 30 per cent by making significant improvements across 24 kilometres of the roadway from Melbourne Airport to Power Street.
The project will see travel times reduced, and commuter safety improved through implementation of a managed motorway system and auto incident detection.
The design joint venture (DJV) delivered a number of innovative solutions including:
To ensure the roads remain operational throughout the project, significant input in relation to traffic staging arrangements has been made. Ultimately, innovative design has saved significant capital costs, minimised traffic disruptions during construction and aided in the overall construction methodology.
