General Information:

The Sturt Highway and Main North Road are major routes connecting New South Wales, Victoria and South Australia. The highway connects the Hume Highway (A31) in NSW with the Newell Hwy (A39) and other major routes of South Western NSW. The route also connects with the Calder Highway (A79) in Victoria.

The highway itself varies from 2-lane rural highway in the less populated areas to multilaned main road in some of the larger towns along the route to freeway standard and 6-lane arterial road standard in Adelaide.

The route receives Auslink funding from the Federal Government, recognising its importance as a major Australian highway for freight and travel.

The Sturt Highway is named after Charles Sturt, who explored south western New South Wales, the Murrumbidgee and Murray Rivers and also parts of central Australia in the 1800s.
