The North–South Motorway is a partially complete motorway traversing the inner western suburbs of Adelaide, from Waterloo Corner in the north to Bedford Park in the south. Progressively constructed in stages since 2010, once complete it will replace the adjacent South Road as Adelaide's main north–south roadway. It will form the central section of the North–South Corridor, being flanked north and south by the Northern Expressway and Southern Expressway, respectively. It is designated part of route M2. By March 2021, approximately of the motorway had been completed, with the remaining under investigation. The full project is planned for completion in 2030. Background In 2010, the Australian Government, through the Nation Building Program project, committed $500 million and the South Australian Government committed $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. In May 2015, a government strategy paper envisioned that the entire non-stop north–south road corridor would be completed by 2025, including "an upgraded South Road". It stated that the planned "non-stop motorway" would "cater for the unimpeded flow of longer distance northbound and southbound trips" and would not include "at-grade traffic signals, intersections, junctions or property accesses which cause vehicles to slow down or stop". Sections The motorway is divided into sections for the purposes of construction. As of March 2021, four sections are complete and one is under investigation. From north to south the sections are: Northern Connector Plans for a motorway connecting South Road and the Northern Expressway surfaced in early 2008 when the Northern Expressway was awaiting construction; the Northern Connector would be an eight-lane motorway linking the Northern Expressway and South Road, with three intermediate interchanges. The project was proposed to include a major diversion in the main ARTC interstate rail line, which would run down the middle of the new motorway between Dry Creek, South Australia and Taylors Road at Waterloo Corner. The federal government proposed that it could be the state's first toll road. In September 2015, the Premier of South Australia, Jay Weatherill and Prime Minister of Australia Tony Abbott announced that the road component of the project would start construction in early 2016. The federal government would provide towards an expected
