Olympic Highway is a rural road in the central western and south-eastern Riverina regions of New South Wales, Australia. The highway services rural communities and links Hume Highway with Mid-Western Highway and provides part of an alternate road link between Sydney and via and as well as servicing Wagga Wagga, linking with Sturt Highway. Route The highway runs generally north–south, roughly aligned to sections of the Sydney–Melbourne and the Blayney–Demondrille railway lines. A section of the highway through Wagga Wagga is a four-lane divided urban road where the highway is concurrent with the Sturt Highway. Olympic Highway approximately parallels Hume Highway to the east and Newell Highway to the west, sharing a short concurrency with Sturt Highway in Wagga Wagga. It is mostly a single carriageway and also includes wider sections within urban areas and some passing lanes. Where the road passes through suburban areas it accommodates both parking and pedestrian needs of the town shopping centre and highway through traffic. At its northern terminus in Cowra, Olympic Highway meets Mid-Western Highway, along which route A41 continues east to Bathurst, and west as route B64 to ; and the Lachlan Valley Way that generally runs northwest–southwest between and and beyond. Olympic Highway heads generally south by west through Koorawatha, , , , Wagga Wagga, and towards its southern terminus via a trumpet interchange with Hume Highway located north of Albury at . The only major river crossing is the Murrumbidgee River, crossed between and Wagga via the Gobbagombalin Bridge, at long believed to be the longest continuous-span viaduct in New South Wales, situated about northwest of the Wagga CBD and opened on 26 July 1997. Prior to the completion of the "Gobba" Bridge, the Olympic Highway followed a route that took it through the Wagga central business district via the Hampden Bridge, a wooden Allan Truss bridge that was opened in 1895 and eventually demolished in 2014. History The passing of the Main Roads Act of 1924 through the Parliament of New South Wales provided for the declaration of Main Roads, roads partially funded by the State government through the Main Roads Board (later the Department of Main Roads, and eventually Transport for NSW). Main Road No. 57 was declared from the intersection with Monaro Highway (today Sturt Highway) at Wagga Wagga to Old Junee and continuing north via Temora, Wyalong, Condobolin and Tullamore to the intersection with North-Western Highway
