The North–South Corridor is a series of road projects currently under construction or planning which travel through Adelaide, South Australia that will eventually be one continuous link from Old Noarlunga in the outer southern metropolitan Adelaide suburbs through to Nuriootpa in the inner northern rural area around the Barossa Valley, a distance of over 100 km, aiming to be without a single stop by 2030.
The route comprises a number of major road links in the metro area, from the Southern Expressway, to South Road, to the elevated North-South Motorway/South Road Superway, to the in-progress Northern Connector, to the Northern Expressway and ending with the continuation of the rural Sturt Highway in the north.
By 2030, all of these major road links (listed South–North) are proposed to have been completed, thus making a major route through the Adelaide metropolitan area a much more efficient way to travel. Its expected to take only one hour to travel from Noarlunga in the South to Gawler in the North.
The components identified by the Department of Planning, Transport and Infrastructure are:
The government has a strategy to deliver the complete project in ten years from May 2015.
The Southern Expressway, 21 km, which originally opened stages 1 and 2 in 1997 and 2001 respectively, as a one way, freeway standard road, which was closed for an hour twice a day, and reversed direction to match peak traffic flow; open northwards (towards city) weekday mornings and weekend afternoons, and open southwards (away from city) weekday afternoons and weekend mornings. Duplication of the Expressway began in 2011, with the construction of a second carriageway making the expressway operate in both directions, 24 hours a day. The expressway opened for two-way traffic on 3 August 2014.
