Adelaide's North-South Corridor project which is being directed by Infrastructure South Australia represents the major route for north and south bound traffic, between Gawler and Old Noarlunga, a stretch of 78 kilometres. Eleven major projects make up the North-South Corridor project, with five currently completed, and six more to be completed in the near future.

$2.5 billion in federal and state funding has been committed to three of the upgrades, including:

● $985 million for the Northern Connector Project, which will connect the Northern Expressway and Port Wakefield Road to the Port River Expressway. Once built, the key section near the port, will have three lanes in either direction, with a speed of 110km/h.

● $896 million for the Torrens Road to River Torrens Project, which is due for completion by the end of 2018.

● $620 million for the Darlington Upgrade Project, which is currently undergoing construction.

The route from River Torrens to Darlington via South Road, Anzac Highway and the Southern Expressway is still undergoing planning and has no funding as yet.

Ultimately, the completion of the North-South Corridor project will benefit the South Australian community and ease congestion in the next 30 years for road users and more importantly freight carriers travelling along the route.
