Set to unlock Adelaide’s traffic network, the T2D Project is the final 10.5km section of the North-South Corridor. Using a combination of tunnels, lowered and surface-level motorway, and overpasses and underpasses at key intersections, the T2D Project will create 78km of non-stop, traffic light-free motorway between Gawler and Old Noarlunga.

The Majors Road Interchange Project will provide commuters in the southern suburbs further access to the Southern Expressway, whilst providing all commuters improved access to Glenthorne National Park - Ityamaiitpinna Yarta, Sam Willoughby International BMX Facility and Southern Soccer Facility from the Southern Expressway.
