With a total land area of 983,482 square kilometres (379,725 sq mi), it is the fourth-largest of Australia's states and territories by area, and fifth largest by population. It has a total of 1.7 million people, and its population is the second most highly centralised in Australia, after Western Australia, with more than 77 percent of South Australians living in the capital, Adelaide, or its environs.

The Northern Expressway, also known as the Fatchen Northern Expressway, is a 23 kilometre long controlled-access highway in Adelaide, South Australia. It travels from Gawler to Port Wakefield Road. The road has been built to four-lane standard and provides a faster route between Adelaide and Gawler, whilst reducing the amount of traffic on Main North Road, which passes through the heart of the northern suburbs and is interspersed with frequent traffic lights. It also allows freight vehicles to avoid residential areas and go straight to Port Wakefield Road and onto the Port River Expressway (A9) to reach the harbour at Port Adelaide.

It is a freeway standard route connecting Main North Road to the Sturt Highway, bypassing Gawler. Major exits include Angle Vale Road, Two Wells Road, Northern Expressway, Mallala Road and Horrocks Highway (formerly Main North Road). Each of these exits also have minor roads leading into Gawler.
Main North Road is the major north-south arterial route through the suburbs north of the Adelaide City Centre in the city of Adelaide, South Australia. It continues north through the settled areas of South Australia and is a total of 307 kilometres (191 mi) long, from North Adelaide to 21 kilometres (13 mi) out of Port Augusta. It follows the route established in the early years of the colony by explorer John Horrocks and was a major route for farmers and graziers to reach the capital, passing through rich farmland and the Clare Valley wine region. In 2011, the section of road between Gawler to Wilmington was renamed Horrocks Highway.
The Sturt Highway is an Australian national highway in New South Wales, Victoria, and South Australia. The Sturt Highway is an important road link for the transport of passengers and freight between Sydney and Adelaide and the regions situated adjacent to the route.
Gawler is the oldest country town on the Australian mainland in the state of South Australia, and is named after the second Governor of the colony of South Australia, George Gawler. It is about 40–44 km (25–27 mi) north of the centre of the state capital, Adelaide, and is close to the major wine producing district of the Barossa Valley. Topographically, Gawler lies at the confluence of two tributaries of the Gawler River, the North and South Para rivers, where they emerge from a range of low hills.
The route was built in 1963 in an attempt to redirect traffic on the national highway out of Gawler town centre and has been upgraded and realigned several times since then.
