The North-South Motorway (previously known as the South Road Superway)[1] is an elevated motorway in the northern suburbs of the South Australian capital city of Adelaide. It has been constructed over a 4 km section of South Road as part of a long term plan to upgrade this road into a non-stop north-south route. At a cost of A$812 million, the motorway is the biggest single investment in a road project in South Australia’s history.[2] The North-South Motorway is stage two of the North–South Corridor upgrade and delivers a 4.8 kilometre section of freeway grade road, including a 2.8 kilometre elevated roadway, from the Port River Expressway to Regency Road. Along the way, it passes over the Dry Creek-Port Adelaide railway line, Cormack Road, Grand Junction Road and Days Road, with exits at Grand Junction Road and Days Road.

Purpose

The Australian Government, through the Nation Building Program project, committed $500 million and the South Australian Government $432 million to the North–South Corridor over five years. This funding allocation recognised that South Road is the only continuous link between the northern and southern suburbs as well as the spine connecting Adelaide’s major inter-modal transport hubs – Adelaide Airport, Islington Rail Terminal, Port Adelaide and Outer Harbor.[3]

Contracting

South Australian civil engineering and construction company, Bardavcol, was awarded the early works local roads contract, with the design and construction contract awarded to Urban Superway Joint Venture, comprising the John Holland Group, Macmahon Contractors and LEED Engineering & Construction.[4]

Construction

Construction of the local connector roads was completed in early 2011, with the completion of construction of Gallipoli Drive. This road replaced South Road as the main distributor road in the area during construction. Construction of the superway proper commenced in early 2011.[5] Construction was completed March 2014. The southbound lanes opened early February 2014, with the left turn entry from Port River Expressway opening on 31 January 2014.[6] The northbound lanes opened on 13 March 2014.[7]
