The Eyre Highway is a highway linking Western Australia and South Australia via the Nullarbor Plain. Signed as National Highway 1/A1, it forms part of Highway 1 and the Australian National Highway network linking Perth and Adelaide. It was named after explorer Edward John Eyre, who was the first to cross the Nullarbor by land. The Eyre Highway starts at Norseman and ends in Port Augusta. The road, and Highway 1, then continues as Port Wakefield Road to Adelaide. There are two parts of the Nullarbor crossing that are now distinct and separate routes to the current Eyre Highway - on the Western Australian side there is a mapped Old Coach Road that is further north towards the Trans Australia Railway line, and on the South Australian side the older highway route runs from Border Village to the Nullarbor Roadhouse - well away from the coast and running through the centre of the Nullarbor National Park.
