General Information:

Highway 1 runs right around Australia, however with the introduction of alphanumeric routes, highway 1 takes on all different identifications depending on its importance and road design.

In South Australia, it's numbered with several designations:

• Eyre Highway (NH-A1):

Named after Edward John Eyre the Eyre Highway is a highway linking Western Australia and South Australia. It forms part of Highway 1 and the Australian National Highway network linking Perth and Adelaide. It is the only sealed road that crosses the SA/WA border.

Access to the spectacular coastline of Great Australian Bight is just a short detour south of the highway in many places. Towns and localites along this section of Highway 1 include Border Village, Nullarbor, Yalata, Nundroo, Penong, Ceduna and Port Augusta.

History:
