McKillops Bridge is a significant engineering feat located in the Snowy River National Park in Victoria, Australia. It was built between 1931-36 and completed in 1936 to replace its predecessor destroyed by a freak flood before it could be officially opened. The bridge is based on welded-steel trusses seated on tall one-piece reinforced-concrete piers. It was regarded as one of the standing wonders of Australian road-bridge engineering in the 1930s and claimed by its builders to be the longest welded-steel-truss road bridge in the world at that time.
