Route Numbering:

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. This page concentrates solely on the former National Highway portions of the route within South Australia.

The National Highway 1 section of Princes Highway links Adelaide and Tailem Bend. Originally the highway was first proclaimed from Sydney to Melbourne in the 1920s, and was later extended through western Victoria and eventually to Adelaide.

Towns along this section of NH1 include Tailem Bend, Murray Bridge, Nairne, Mount Barker and Adelaide. The route varies from 2 lane rural highway standard to full freeway standard. 1

Port Wakefield Road branches off of Main North Road at Gepps Cross in the northern suburbs of Adelaide. The highway is dual-carriageway until Port Wakefield and connects Adelaide to Port Augusta. Towns and cities along the route include Adelaide, Two Wells, Port Wakefield, Snowtown, Crystal Brook, Port Pirie, Port Germein, Stirling North and Port Augusta.

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. 2

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.
