Barrier Highway is a highway inSouth Australia^[4] andNew South Wales, and is designated part of route A32. The name of the highway is derived from theBarrier Ranges, an area of moderately high ground in the far west of New South Wales, through which the highway traverses.

Route

[edit]

Barrier Highway branches offHorrocks Highway atGiles Corner, betweenRiverton andTarlee and heads northeast, crossing the border intoNew South Wales and passing throughBroken Hill. It continues further east toWilcannia where it crosses theDarling River, pastCobar to eventually end inNyngan, where it joinsMitchell Highway. The area traversed by the highway is remote and very sparsely settled.

History

[edit]

The passing of theMain Roads Act of 1924^[5] through theParliament of New South Wales provided for the declaration of Main Roads, roads partially funded by the State government through theMain Roads Board (laterTransport for NSW).Barrier Highway was declared (as Main Road No. 8) on 8 August 1928, from the intersection with North-Western Highway (todayMitchell Highway) in Nyngan, via Cobar, Willcannia, and Broken Hill, to the border with South Australia;^[2] with the passing of theMain Roads (Amendment) Act of 1929^[6] to provide for additional declarations of State Highways and Trunk Roads, this was amended to State Highway 8 in April 1929.

The highway was fullysealed in October 1972.^[7]

The passing of theRoads Act of 1993^[8] through theParliament of New South Wales, updated road classifications and the way they could be declared within New South Wales. Under this act, Barrier Highway today retains its declaration as Highway 8, from Nyngan to the state border with South Australia.^[9]

Barrier Highway was signed as National Route 32 across its entire length in 1955. With both states' conversion to their newer alphanumeric systems in 1998 and 2013, its former route number was updated to A32 for the highway within South Australia in 1998, and within New South Wales in 2013.^[10]
