Olympic Highway is a 317-kilometre (197 mi) rural road in the central western and south-eastern Riverina regions of New South Wales, Australia.

Where the road passes through suburban areas it accommodates both parking and pedestrian needs of the town shopping centre and highway through traffic.

Olympic Highway heads generally south by west through Koorawatha, Young, Cootamundra, Junee, Wagga Wagga, and Culcairn towards its southern terminus via a trumpet interchange with Hume Highway located 18 kilometres (11 mi) north of Albury at Table Top.

[4][5] The only major river crossing is the Murrumbidgee River, crossed between Boorooma and Wagga via the Gobbagombalin Bridge, at 1.4 kilometres (0.87 mi) long believed to be the longest continuous-span viaduct in New South Wales, situated about 6 kilometres (3.7 mi) northwest of the Wagga CBD and opened on 26 July 1997.

239 was declared from Young to Wombat (and continuing southwards to Murrumburrah, and northwards to Grenfell),[2] and Main Road No.
