SA’s Torrens to Darlington early works get underway

More than $85 million in preparatory early works are now underway on the $9.9 billion Torrens to Darlington (T2D) project in Adelaide, the final piece of South Australia’s 78-kilometre North-South Corridor.
The South Australian Government has selected a hybrid+ option to deliver the T2D project, using a combination of tunnels, lowered and ground-level motorways, as well as overpasses and underpasses at key intersections.
When complete, around 60 per cent of the T2D Project will be comprised of underground tunnels, with the second stage construction between the River Torrens and Anzac Highway including a second tunnel.
“The Morrison Government has invested billions in the North-South Corridor – the most significant infrastructure project ever undertaken in the state – as part of its record $110 billion infrastructure investment pipeline, which is helping to drive the nation’s world-leading economic recovery,” Minister Fletcher said.
“When finished, this project will bypass 21 sets of traffic lights between the River Torrens and Darlington, with the journey taking on average 8 minutes, saving motorists up to 24 minutes in travel time.”
Major construction of the Southern Tunnels is expected to commence in late 2023, pending relevant approvals, with the entire 10.5 km project expected to be completed in 2030.
