The North-South Corridor is identified in the following strategies as one of Adelaide’s most important transport corridors - the South Australian Planning Strategy including the 30 Year Plan for Greater Adelaide, the Strategic Infrastructure Plan for SA and the Integrated Transport and Land Use Plan. It will be the major route for north and south bound traffic, including freight vehicles, running between Gawler and Old Noarlunga, a distance of 78 kilometres.
The current roadway is not working effectively and will not be able to handle the projected number of vehicles that will need to use the road, or cater for the size of freight carriers wanting to travel along it. In response, the Australian and South Australian Governments are working collaboratively to expand the route by creating a dedicated non-stop North-South Corridor.
