Projects Nearby: North-South Corridor/Darlington Upgrade

The Darlington Upgrade Project is an important stage in the delivery of Adelaide's North-South Corridor and will deliver an upgrade of approximately 3.3 kilometres of the existing Main South Road, including:

• A non-stop motorway between the Southern Expressway and Tonsley Boulevard
• A lowered, non-stop motorway passing underneath Flinders Drive, Sturt Road, Sutton Road/Mimosa Terrace and Tonsley Boulevard
• Grade separation of the Main South Road/Ayliffes Road/Shepherds Hill Road intersection
• Main South Road (at grade) surface roads along both sides of the lowered motorway to provide connections to Flinders Drive, Sturt Road and most local roads
• Full free flow interchange at the Southern Expressway/Main South Road with dedicated ramps providing direct access to the new motorway and Main South Road

The Morrison and Marshall Governments have put $5.4 billion on the table towards completion of the final section of the North-South Corridor, between Darlington and the River Torrens. Once complete, the 78-kilometre North-South Corridor will be the major non-stop route for north and south bound traffic, running between Gawler and Old Noarlunga. The final 10.5-kilometre section will link the Darlington upgrade which is currently under construction to the recently-opened Torrens to Torrens project.
