The Darlington Upgrade Project is another important stage in the delivery of Adelaide’s North-South Corridor and will deliver an upgrade of approximately 3.3 kilometers 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 Gateway South Joint Venture of Fulton Hogan and Laing O’Rourke has engaged ESO to provide survey resources to the $620mill project.

Work has commenced in earnest with construction expected to be complete at the end of 2018.
