Highways in New South Wales

(the full list of main roads gazetted appears in the Government Gazette of the State of New South Wales of 17 August 1928).

The number of a road for administrative purposes is not the same as the route number it carries e.g. the Great Western Highway is Highway 5 for administrative purposes but is signposted as part of route A32.)

Many major routes in New South Wales, including Sydney motorways and even some routes named as "highways" are not officially gazetted as highways.

For a list of all numbered routes in New South Wales, see List of road routes in New South Wales.

These names typically come from 19th-century explorers, important politicians or geographic regions.
