High altitude section of Snowy Mountains Highway with distinctive yellow lane marking

Snowy Mountains Highway is a 333-kilometre-long (207 mi) state highway located in New South Wales, Australia. Its two sections connect the New South Wales South Coast to the Monaro region, and the Monaro to the South West Slopes via the Snowy Mountains. The higher altitude regions of this road are subject to snow over the winter months, and the road also provides access to many parts of the Snowy Mountains Scheme. The highway bears the B72 shield along its entire length.

The highway originally bore the name Monaro Highway until 1955, when it received its current name. It originally ran from Tathra to Wagga Wagga but has been shortened to run from Princes Highway to Hume Highway instead. Reservoirs created as a result of dams built in the 1950s and 1960s as part of the Snowy Mountains Scheme required the creation of major realignments to avoid submerged areas. Previous to New South Wales' conversion to alphanumeric route markers, it was signed as National Route 18. (Full article...)
