Project Description

The upgrading program consists of implementing a suite of safety related measures as well as pavement rehabilitation projects. Projects in the package include:

  • new overtaking lanes and extensions of existing overtaking lanes;
  • pavement rehabilitation;
  • new rest areas and upgrades to existing rest areas;
  • mitigation of roadside hazards (including hazard removal and installation of barriers); and
  • improved centrelines and median dividing treatments.

As part of this corridor upgrade, the South Australian Government has committed $20 million to undertake work on the South Eastern Freeway and Princes Highway sections of the corridor.


The main strategic drivers of this program are the safety and efficiency of passenger and freight movements along the corridor.

The package of works will improve safety, infrastructure handling capacity and efficiency, transport productivity and travel reliability on this nationally strategic and export oriented freight corridor.


The Australian Government provided $80 million to this $100 million project.


Construction commenced in March 2009 and several initial projects were completed in December 2009. The full package of works was completed in mid 2014.
