Torrens to Darlington Project (T2D)

The Torrens to Darlington (T2D) section is the final piece of South Australia’s world-class multi-billion dollar North-South Corridor, and the key to unlocking Adelaide’s traffic network, while delivering important economic, employment and safety benefits to the state.

The South Australian Government has announced that the hybrid+ option is the preferred way to deliver the T2D Project, which will see a combination of tunnels, lowered and ground-level motorways, as well as overpasses / underpasses at key intersections to successfully complete the free-flowing transport route.

When complete, around 60% of the T2D Project will be underground tunnels, with completion expected in 2030.

Creating up to 4,000 jobs, this congestion busting project will allow motorists to bypass 21 sets of traffic lights when travelling between the River Torrens and Darlington, and reduce travel time by 24 minutes.

Construction of this 10.5 km section of motorway will be the state’s biggest infrastructure project to date and will deliver a 78 km, non-stop traffic-light-free connection between Gawler and Old Noarlunga, with links to the port and airport precincts.
