General Information:

Horrocks Highway (formerly Main North Road) is a major arterial route linking Adelaide and the Flinders Ranges and Port Augusta area.

The Barrier Highway heads north from Giles Corner into the mid-north of South Australia. The highway also passes through the Nackara Range, and heads north-easterly direction eventually reaching Cockburn, which is located on both the SA/NSW border - split in half by the actual border. The highway is named after the Barrier Ranges which are located near Broken Hill.

The roadwork had commenced in 1961 and included 19 bridges.
