The Torrens to Torrens project will deliver a 4km non-stop section of South Road between Torrens Road and the River Torrens. It includes a 3km lowered motorway under Hawker Street and the Torrens, Port and Grange road intersections, as well as a rail overpass for the Outer Harbor line and a shared use pedestrian and cycling bridge.

To date more than 2.1 million on-site hours have been worked on the project with more than 95% completed by South Australians.

In addition, South Australian companies are being used on the project to provide materials and services with more than $185 million of work packages being awarded to local businesses to the end of 2017 - almost 98% of the total value of works packages awarded so far.

Construction on the jointly funded project - the federal and state governments committed $400.5 million each - commenced in August 2015 and to date, excavation of the 3km lowered motorway is more than two thirds complete with approximately 250,000 cubic metres of soil already removed. But that's not all.

"Not only did we manage to extend the project past Torrens Road within the existing budget, we also reallocated almost $100 million of savings to deliver the $174.3 million Oaklands Crossing Project," SA Transport and Infrastructure Minister Stephen Mullighan said.
