The Darlington Upgrade project involves reconfiguration of approximately 3.3km of South Road from the Southern Expressway to north of Tonsley Boulevard into an expressway-standard road. It includes a lowered non-stop motorway that passes underneath Flinders Drive, Sturt Road, Mimosa Terrace/Sutton Road, Ayliffes Road and Tonsley Boulevard, at-grade service roads, and a full free flow interchange at the Southern Expressway/Main South Road junction.
The project is part of the North-South Corridor, which 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.
The Darlington Upgrade project will upgrade the North-South Corridor through the following benefits:
- reduced travel times for long distance north-south movements through Darlington
- reduced travel times for arterial road and local road movements
- improved freight transport productivity in Adelaide
- enhanced productivity and increased competitiveness for export industries
- reduced traffic congestion and improved safety at this critical location
- improved north-south traffic flows along the corridor
- improved connectivity for east-west traffic by reducing delays at South Road intersections
The Australian Government is contributing $533.6 million towards the $667 million project.
Construction commenced in April 2016 and is expected to be completed in mid 2020.
