Darlington Upgrade Project

The $620m Darlington Upgrade Project features a 3.3 kilometre non-stop road link connecting the Southern Expressway and Tonsley Boulevard.

The project features:

  • 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) service 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
  • An upgrade to the Marion Road/Sturt Road intersection to cater for the redistribution of traffic during the construction period.

Engineering Surveys as Project Surveyors will be involved in all aspects of surveying requirements on this impressive South Australian project including road works, bridge works and services.  Teams use Trimble S6 and S8 robotic total stations along with GPS units.
