The Cobb Highway is a state highway in the western Riverina and the far western regions of New South Wales, with a short section in Victoria, Australia.Initially an amalgam of stock routes, the 571-kilometre (355 mi) Cobb Highway was proclaimed during the late 1930s, initially extending from the New South Wales and Victorian border north to Wilcannia, White Cliffs and Tibooburra to Warri Gate at the New South Wales and Queensland border.
