Taradale Viaduct, Railway viaduct in Taradale, Victoria, Australia

Taradale Viaduct is a wrought iron box girder bridge over Back Creek at Taradale, Victoria, carrying the Bendigo Railway on masonry piers. The ironwork was made by Rowland Brotherhood of Chippenham, Wiltshire, under the supervision of Isambard Kingdom Brunel. Steel trestles were added between the original piers in 1933-1934 to carry heavier locomotives.

Construction of the Bendigo line began in 1858 under the Melbourne, Mount Alexander and Murray River Railway Company, which ran into financial trouble and was bought out by the Victorian colonial government in 1860. The design was then taken over by Captain Andrew Clarke, with the bridge designed by Bryson and O'Hara. The foundation stone was laid on 25 September 1861, and the ironwork was made by Rowland Brotherhood under the supervision of Isambard Kingdom Brunel. In 1933–34, steel trestles were added between the original masonry piers to carry heavier locomotives.

The viaduct carried the Bendigo line over Back Creek, linking the goldfields and farms around Taradale to Melbourne. Its ironwork was made by Rowland Brotherhood of Chippenham, Wiltshire, under the supervision of Isambard Kingdom Brunel, and the foundation stone was laid by W. S. Urquhart on 25 September 1861. The bridge is listed on the Victorian Heritage Register (H1595) and the National Trust Register.

Royal Oaks Park nearby offers the best vantage point with walking tracks that lead beneath the structure for close-up views. The site is accessible year-round, though the area around the creek can be muddy after rain.

The ironwork design was overseen by celebrated engineer Isambard Kingdom Brunel, known for pushing the limits of Victorian engineering. The metal components were fabricated by Rowland Brotherhood in Wiltshire, England, making this an unusual international collaboration for a remote Australian railway.
