The Stuart Highway is one of Australia's major highways. It is a segment of Australia's Highway 1 extending from Darwin, Northern Territory, in the north, via Tennant Creek and Alice Springs, to Port Augusta, South Australia, in the south—a distance of 2,834 kilometres (1,761 mi). The principal north-south route through the central interior of mainland Australia, the highway is often referred to simply as "The Track". The highway is named after John McDouall Stuart, who was the first European to cross Australia from south to north. The highway generally follows the route that John McDouall Stuart took to get from north to south.---------At the Northern Territory/South Australia border the route number changes from National 87 to National A 87. The Stuart Highway passes through the Far North region and continues to Adelaide, but its proper routing is from Port Augusta. The highway passes through the Woomera Prohibited Area where travellers may not leave the road. The highway continues south-east towards Adelaide. There is petrol and other facilities (meals, toilets, etc) available at reasonable intervals (usually around 200 km/120 mi) and more frequent rest stops. Some of the rest stops are located at scenic points with information boards, but others are little more than a picnic table and a rubbish bin in the middle of nowhere.
