Set to unlock Adelaide’s traffic network, the T2D Project will create 78 km of non-stop, traffic light-free motorway between Gawler and Old Noarlunga.

The project will provide commuters in the southern suburbs further access to the Southern Expressway, and improved access to Glenthorne National Park - Ityamaiitpinna Yarta, Sam Willoughby International BMX Facility and Southern Soccer Facility.

The Main South Road and Victor Harbor Road duplication projects will create safer and faster journeys for motorists, provide a vital boost for local tourism and communities, and support hundreds of jobs each year during construction.
