Construction has wrapped up on the new Selgar Avenue link road, one of the first of a number of construction projects that form part of the $15.4 billion Torrens to Darlington motorway in South Australia.
The Torrens to Darlington (T2D) project is the largest road infrastructure project in South Australia’s history and when complete in 2030, it will provide a 78-kilometre non-stop, traffic light-free North-South Corridor between Gawler and Old Noarlunga.
Using a combination of tunnels, lowered and ground-level motorways, as well as overpasses and underpasses at key intersections, T2D will bypass 21 sets of traffic lights between the River Torrens and Darlington. When complete, around 60 per cent of the T2D Project will be comprised of underground tunnels.
Stage One (Southern Tunnel) between Anzac Highway and Darlington will including more than four kilometres of tunnel. Stage Two (Airport Link and Northern Tunnel) between the River Torrens and Anzac Highway will include a second tunnel and at-surface motorway.

- Milestone for new Glenrowan bridge
Additional works on the T2D Motorway are underway, including completing the nearby Tonsley East Substation, which will supply electricity to the tunnel-boring machines (TBMs) and then to the two parallel four-kilometre-long southern tunnels once they are completed in 2030.
South Australian Minister for Infrastructure and Transport Tom Koutsantonis said the milestone is the first taste of improved road network connectivity being delivered as part of the largest infrastructure project in the state’s history.
“This package is delivering additional network and amenity upgrades along and around the 10.5-kilometre Torrens to Darlington Project to ensure the proper functioning of the motorway and wider road network both during and after construction,” Koutsantonis said.
“The newly constructed Selgar Avenue link road will allow southbound motorists to turn right from Selgar Avenue onto South Road, which is a great outcome particularly for businesses operating in the Selgar Avenue-Drury Terrace area.”
Main construction for the Selgar Avenue link road was delivered by Bardavcol.
The T2D project is being jointly funded by the Federal and South Australian governments on a 50:50 basis.
