About

The 78 km North-South Corridor will unlock Adelaide’s transport network by providing a non-stop traffic-light-free connection between Gawler and Old Noarlunga, with links to the port and airport precincts. The corridor consists of the following sections of non-stop motorway:

  • Southern Expressway
  • Darlington Interchange
  • Torrens to Torrens
  • South Road Superway
  • Northern Connector
  • Northern Expressway

The Australian and South Australian governments are getting on with completing the final sections of the corridor including the $354 million Regency Road to Pym Street Upgrade, due for completion in early 2022, and the final and most complex section between the River Torrens and Darlington, the Torrens to Darlington Project (T2D).
