The South Eastern Freeway


A $14.2 million investment is set to deliver a third lane on South Australia’s South Eastern Freeway between Crafers and Stirling in both directions.

Jointly funded by the state and federal governments, it involves the conversion of the existing emergency lanes into full-time traffic lanes and installation of Intelligent Transportation Systems (ITS) infrastructure.

Currently, almost 54,000 vehicles each day use South Eastern Freeway, with increased commuter and freight traffic forecast from new developments in the Adelaide Hills, including Mount Barker and Murray Bridge will continue to exacerbate the issues.

Federal transport minister Michael McCormack says the project comprises of the delivery of a non-stop three-lane managed motorway to improve traffic flow on the freeway as well as addressing a key capacity bottleneck.

South Australian Minister for Transport, Infrastructure and Local Government Stephan Knoll adds: "The third lane on the South Eastern Freeway in each direction between Crafers and Stirling will help ease traffic congestion and reduce travel times for the 54,000 motorists using this section of the freeway every day.

"This important upgrade will also improve the passage of freight between South Australia and the eastern states as 10 per cent of the traffic using the freeway are heavy vehicles."

"This is a much-needed safety improvement to fix the Crafers to Stirling choke point. Having long called for freeway expansion at this major congestion point, I am proud to see this key safety investment delivered."

The upgrade will incorporate the following works:

  • road shoulder widening to allow three trafficable lanes on both the eastbound and westbound side of the Freeway;
  • upgrade road lighting for the extent of the works;
  • relocation of safety barrier (as required);
  • improved drainage;
  • upgrading pavement and new bitumen surfacing;
  • audio tactile line marking and pavement marking;
  • Automated incident detection using Video Automated Incident Detection technology; and
  • associated ITS Infrastructure including CCTV and variable speed limit signage.

An Invitation to Supply (ITS) has been released inviting two companies to tender for the Intelligent Transportation Systems part of the project.
