In South Australia, Highway 1 is a 1,715-kilometre (1,066 mi)[1] long route that follows the coastline of the state, from the Victorian border near Mount Gambier to the Western Australian border near Eucla. Highway 1 continues around the rest of Australia, joining all mainland state capitals, and connecting major centres in Tasmania. All roads within the Highway 1 system are allocated a road route numbered M1, A1, B1 or R1, depending on the state route numbering system. In South Australia, most of the highway is designated as route A1, with multi-lane, dual-carriage-way sections generally designated route M1, and the alignment around the Adelaide CBD designated route R1. South-east of Tailem Bend, it is designated route B1.

History edit

Highway 1 was created as part of the National Route Numbering system, adopted in 1955. The route was compiled from an existing network of state and local roads and tracks.[2] It was meant to be a National Route between the Victorian Border near Mt. Gambier and Adelaide. In 1958, it was extended northward from Adelaide to Port Augusta, and westward, toward the Eyre/Lincoln highway junction. The Eyre Highway, the Port Wakefield-Port Augusta Road, Port Wakefield Road, and the South Eastern Freeway were declared National Highways in November 1974. Since, the route has remained static.[3]
