Project Description

The South Road Superway project upgraded South Road between the Port River Expressway and Regency Road.

The project involves a 4.8 kilometre non-stop, north-south transport corridor, including :

  •  a 2.8 kilometre elevated roadway;
  • an at-grade service road along the majority of the corridor; and
  • accessibility improvements for the local road network within the project area.


By providing non-stop travel on South Road from the Port River Expressway to Regency Road, the project improves safety for all users - pedestrians, cyclists and motorists - and reduces delay and congestion at the major intersections and at the Wingfield rail line, through grade separation at these sites.


The Australian Government provided $406 million to the project, in partnership with the South Australian Government.


Local roadworks on the South Road Superway, involving the construction of a new link parallel to South Road between Grand Junction Road and Regency Road, commenced in April 2010 and were completed in February 2011. 

Major works on the Superway commenced in April 2011.  The Superway's southbound lanes were opened to traffic on 31 January 2014.  The northbound lanes opened in March 2014, effectively completing the project.
