Tourist Drive 14 is a route in the New South Wales Southern Highlands. The route is a mix of single 2-lane carriageway or 4-lane single carriageway. The route between Mittagong and Aylmerton used to be part of the main route between Sydney and Melbourne, both Great South Road and Hume Highway, and the section between Bowral and Sutton Forest was once part of the Great South Road.
Parts of the route, in one form or another, started life as the Great South Road, linking Sydney with the southern highlands and eventually beyond. in 1928, the route was named Hume Highway after Hamilton Hume (1797-1873), a famous explorer in the early 19th century who, in 1824, in conjunction with William Hovell first found an overland route between Sydney and the infant colonial outpost of Port Phillip, the original name of Melbourne.
The route passes through several historically significant towns including Bowral, where Australian cricketing legend Donald Bradman spent most of his time growing up. The town is also home to Corbett Gardens, where an annual tulip festival is held.
