Darlington upgrade and Flinders link

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 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

Major access changes to Flinders Drive and Sturt Road, Bedford Park

A major traffic switch involving the reconfiguration of northbound traffic on Main South Road between the Southern Expressway and Sturt Road will allow for lowered motorway excavation works in this area.

This traffic switch will occur from 8pm Friday 20 July until 6am Monday 23 July and will result in significant changes to the way you access Flinders Drive and Sturt Road. Please see the flyer below from the Department for Planning, Transport and Infrastructure for further details.

The Flinders Link Project will extend the existing Tonsley rail line to Flinders Medical Centre, creating new connections to the health precinct and Flinders University. The project is expected to be completed by mid-2019.

The project will include:

  • A 650 metre extension of the Tonsley rail line linking the Flinders Medical Centre and Flinders University to the rail network, including 520 metres of elevated single track over Sturt Road, Laffer’s Triangle and Main South Road
  • Removal of the existing Tonsley Station and construction of a new station adjacent to the Flinders Medical Centre; and
  • An integrated shared pedestrian/cycle path adjacent the rail line.
