The Barrier Highway is a highway in New South Wales [1] and South Australia [2] signposted as part of route A32.

Highway A public road or other public way on land

A highway is any public or private road or other public way on land. It is used for major roads, but also includes other public roads and public tracks: It is not an equivalent term to controlled-access highway, or a translation for autobahn, autoroute, etc.

New South Wales State of Australia

New South Wales is a state on the east coast of Australia. It borders Queensland to the north, Victoria to the south, and South Australia to the west. Its coast borders the Tasman Sea to the east. The Australian Capital Territory is an enclave within the state. New South Wales' state capital is Sydney, which is also Australia's most populous city. In March 2018, the population of New South Wales was over 7.9 million, making it Australia's most populous state. Just under two-thirds of the state's population, 5.1 million, live in the Greater Sydney area. Inhabitants of New South Wales are referred to as New South Welshmen.

South Australia State of Australia

South Australia is a state in the southern central part of Australia. It covers some of the most arid parts of the country. 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. Other population centres in the state are relatively small; Mount Gambier, the second largest centre, has a population of 28,684.

The Barrier Highway starts at Nyngan where it joins the Mitchell Highway. It heads west past Hermidale and Boppy Mountain to Cobar, a mining town. It then continues to Wilcannia where it crosses the Darling River. Further west it passes through Broken Hill and enters South Australia, turning southwest towards Adelaide. It joins Main North Road at Giles Corner between Riverton and Tarlee. Route A32 continues on Main North Road to Gawler where it joins Route A20 (the Sturt Highway).

Mitchell Highway highway in Queensland and New South Wales

The Mitchell Highway is a state highway located in the central and south western regions of Queensland and the northern and central western regions of New South Wales in Australia. The southern part of the Mitchell Highway forms part of the National Highway A32 corridor, which stretches from Sydney to Adelaide via Dubbo and Broken Hill. The Mitchell Highway also forms part of the shortest route between Sydney and Darwin, via Bourke and Mount Isa; making it an important road link for the transport of passengers and freight for regional New South Wales and Queensland.

Darling River river in Australia

The Darling River is the third longest river in Australia, measuring 1,472 kilometres (915 mi) from its source in northern New South Wales to its confluence with the Murray River at Wentworth, New South Wales. Including its longest contiguous tributaries it is 2,844 km (1,767 mi) long, making it the longest river system in Australia.

Adelaide City in South Australia

Adelaide is the capital city of the state of South Australia, and the fifth-most populous city of Australia. In June 2017, Adelaide had an estimated resident population of 1,333,927. Adelaide is home to more than 75 percent of the South Australian population, making it the most centralised population of any state in Australia.

The area traversed by the Barrier Highway is remote and very sparsely settled. The name of the highway is derived from the Barrier Ranges, an area of moderately high ground in the far west of New South Wales, which the highway traverses.

Barrier Ranges mountain in Australia

The Barrier Ranges or sometimes the Barrier Range and historically the Stanley's Barrier Range, is a mountain range that comprises a series of hills and higher grounds in the far western region of New South Wales, Australia, surrounding the city of Broken Hill.

Highways in Australia describes the highways of Australia

Highways in Australia are generally high capacity roads managed by state and territory government agencies, though Australia's federal government contributes funding for important links between capital cities and major regional centres. Prior to European settlement, the earliest needs for trade and travel were met by narrow bush tracks, used by tribes of Indigenous Australians. The formal construction of roads began in 1788, after the founding of the colony of New South Wales, and a network of three major roads across the colony emerged by the 1820s. Similar road networks were established in the other colonies of Australia. Road construction programs in the early 19th century were generally underfunded, as they were dependent on government budgets, loans, and tolls; while there was a huge increase in road usage, due to the Australian gold rushes. Local government authorities, often known as Road Boards, were therefore established to be primarily responsible for funding and undertaking road construction and maintenance. The early 1900s saw both the increasingly widespread use of motorised transportation, and the creation of state road authorities in each state, between 1913 and 1926. These authorities managed each state's road network, with the main arterial roads controlled and maintained by the state, and other roads remaining the responsibility of local governments. The federal government became involved in road funding in the 1920s, distributing funding to the states. The depression of the 1930s slowed the funding and development of the major road network until the onset on World War II. Supply roads leading to the north of the country were considered vital, resulting in the construction of Barkly, Stuart, and Eyre Highways.
