The Taradale Viaduct is a large wrought iron box girder bridge over Back Creek at Taradale, Victoria on the Bendigo Railway in Victoria Australia. It was erected as part of the Melbourne, Mount Alexander and Murray River Railway between 1858 and 1861, and was at the time one of the largest rail bridges built in Australia. The contract for the first stage of the line from Footscray to Sandhurst (now Bendigo), was let to Cornish and Bruce for £3,356,937.2s.2d ($6.714 million) with work commencing on 1 June 1858. Completion of the permanent way was to be by 31 July 1861.
