Project Description

Upgrade the North-South Corridor to a non-stop 78 kilometre motorway between Gawler and Old Noarlunga.


An upgraded North-South Corridor will improve freight transport productivity in Adelaide. The corridor is a critical route for the movement of freight and business-related passenger traffic, connecting the Port of Adelaide, Adelaide Airport, the Islington intermodal terminal and other freight terminals. Improvements to the corridor will contribute to enhanced productivity and increased competitiveness for export industries.

The projects are expected to improve safety by creating a free flowing link along one of Adelaide's most important transport corridors and complete a non-stop 78 kilometre motorway between Gawler and Old Noarlunga. 


The Australian Government has committed $2.99 billion to critical projects on the North-South Corridor.  This includes $1.21 billion towards future stages on the North-South Corridor.


Work on the Torrens to Torrens project began August 2015.  Work on the Darlington and Northern Connector projects began in 2016.  Work is expected to be completed in 2018 on the Torrens to Torren project, mid 2019 on the Darlington Upgrade project and in late 2019 for the Northern Connector project.  Work is expected to commence on the Regecy Road to Pym Street project in 2019 and be completed in 2022.
