Contract awarded for $354M North-South Corridor

Urban Infrastructure Minister Alan Tudge has announced successful tender for the major works contract on the $354.3 million North-South Corridor – Regency Road to Pym Street Project.

A consortium of McConnell Dowell Constructors, Mott MacDonald Australia and Arup Group will design and construct a new 1.8 kilometre motorway along South Road, connecting the South Road Superway to the Torrens to Torrens Project.

The consortium are currently working together on the delivery of the Oaklands Crossing Grade Separation Project, and have previously been involved in the delivery of large-scale infrastructure projects in South Australia.

Mr. Tudge said the project is the final missing link between Gawler and the River Torrens.

“When complete, the project will deliver efficient and reliable travel for up to 53,000 vehicles per day, by removing the need to travel through two signalised intersections,” Mr. Tudge said.

The Federal and South Australian governments are jointly funding the project as part of their overall commitment to build a non-stop 78-kilometre North-South Corridor between Gawler and Old Noarlunga.

The concept design includes:

  • A 1.8 kilometre section of non-stop roadway, providing three lanes in each direction at-grade.
  • Two lanes in each direction on the South Road surface road, providing access to the surrounding community and local businesses.
  • An overpass over Regency Road, with three lanes in each direction, and two lanes in each direction on the surface roads underneath.
  • Left in and left out only access at Pym Street.
  • Full access to and from the non-stop motorway at Regency Road.
  • Intersection upgrade at Regency Road.
  • Improved cycling and pedestrian facilities.
  • A grade separated pedestrian and cycle overpass over South Road in the vicinity of Pym Street.
  • Landscaping and noise barriers.

Main construction works for the upgrade are expected to commence in late 2019, with completion expected in 2022.
