Project Description

The project involved the upgrade and widening of South Road from Pym Street to approximately 100 metres south of the River Torrens, including a 4 km non-stop section of roadway (which incorporates a 3 kilometre section of lowered motorway) and the grade separation of two major arterial roads (Port Road and Grange Road).  Work also included an overpass of the Outer Harbor rail line and improved cycling and pedestrian facilities.


The North-South 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 contributes to enhanced productivity and increased competitiveness for export industries.

The Torrens Road to River Torrens project addresses one of the highest priority sections of the corridor, providing relief from traffic congestion and improved safety at this critical location. An upgraded South Road will not only improve north-south traffic flows along the corridor, but will also improve connectivity for east-west traffic by reducing delays at South Road intersections.


The Australian Government has committed $383.5 million towards the $767 million project.


Construction began in August 2015 and was completed in late 2018.
