The Gunbarrel Highway is an isolated desert track in the Northern Territory, South Australia and Western Australia. It consists of about 1,350 km (840 mi) of washaways, heavy corrugations, stone, sand and flood plains. The Gunbarrel Highway connects Victory Downs in the Northern Territory to Carnegie Station in Western Australia. Some sources incorrectly show the highway extending west to Wiluna. The road was built as part of Australia's role in the weapons research establishment called Woomera which included Emu Field and Maralinga, both atomic bomb testing sites.
