The Australian and South Australian Governments have jointly committed $354m to construct the project as part of their overall commitment to build a non-stop North-South Corridor.
The project includes the design and construction of a new 1.8 kilometre section of non-stop motorway along South Road, as part of Adelaide’s North-South Corridor initiative.
The new Regency Road to Pym Street motorway will connect the completed motorway sections to the north of Regency Road (South Road Superway) to the completed motorways section (Torrens Road to River Torrens Project) terminating north of Torrens Road. This will result in a 47 kilometre non-stop motorway between Gawler and the River Torrens, and continues to deliver on the Australian and South Australian Governments’ commitment to complete the North-South Corridor.
The project comprises an at-grade motorway from the existing motorway infrastructure to the north (South Road Superway); an overpass of the motorway over Regency Road; and an at-grade motorway from Regency Road to Pym Street, transitioning to the lowered motorway infrastructure (Torrens Road to River Torrens Project). 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 (three lanes in each direction). Two lanes in each direction (at-grade) 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.
The project once complete will deliver travel time savings of up to 8 minutes during peak periods (or 4.5 minutes on average) on South Road between Regency Road and Pym Street.

The procurement for this project is in its second stage, with contract award anticipated for late June/early July 2019.
In early December 2018, DPTI issued an ROI which sought pre-registration from interested parties and provided project information in advance of the formal EOI process. The EOI process commenced on 13 December 2018 and concluded on 5 February 2019, with the following two consortia shortlisted to participate in the Request for Proposal phase.
- CPB, GHD and SMEC; and
- McConnell Dowell, Mott MacDonald and ARUP.
The Request for Proposal phase, which commenced in March 2019, is a 13 week process which requires Proponents to develop a Project Proposal and Target Outturn Cost to deliver the project.
