The 10.5km final piece of South Australia’s world-class North-South Corridor will complete a 78 km non-stop, traffic light-free connection between Gawler and Old Noarlunga, with links to the port and airport precincts.

The South Australian Government has announced that a hybrid+ option will be used to deliver the T2D Project, using a combination of tunnels, lowered and ground-level motorways, as well as overpasses and underpasses at key intersections.

Stage One (Southern Tunnel) between Anzac Highway and Darlington will including more than 4km 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.

When complete, around 60 per cent of the T2D Project will be comprised of underground tunnels.

The project will support more than 4,500 jobs during construction.

This project will allow motorists to bypass 21 sets of traffic lights and save up to 24 minutes’ travel time between River Torrens and Darlington.
