The Silver City Highway is a 683-kilometre-long (424 mi) highway that links Buronga, New South Wales to the Queensland border via Wentworth, Broken Hill, and Tibooburra, in the arid Far West region of New South Wales. A short branch also connects to the Calder Highway on the Victorian border at Curlwaa. This branch is also signed as the Calder Highway, despite legally being part of the Silver City Highway. Parts of the highway north of Broken Hill are unsealed.

The route passes through largely arid terrain, although there are multiple irrigated areas between Buronga and Wentworth in the highway's south. There is relatively flat terrain between Wentworth and Broken Hill that forms arid pastures for grazing. Around Broken Hill and a little to the north the Barrier Range is encountered, which is more hill than the rest of the route encountered so far, but not mountainous. North of there the country is once again relatively flat, thought there are further hills around Milparinka. Near Tibooburra the terrain becomes a stony desert, this kind of terrain is known in Australia as gibber. There are some unsealed sections of highway north of Broken Hill.

Creeks to the north of Broken Hill are generally crossed straight across the riverbed, whether the road has been sealed or not. There is signage to help drivers gauge depth of the waters if there does happen to be flows after rains. The highway also roughly follows the route Charles Sturt took when he explored the area, during his search to find the fabled inland sea. The Silver City Highway and its spur are classified as HW22 (Highway 22) by Roads & Maritime Services. The route is signed as B79 between the Abbotsford Bridge in Curlwaa and Broken Hill.
