Prince Alfred Bridge, Truss bridge in Gundagai, Australia

Prince Alfred Bridge is a wrought iron truss and timber beam road bridge over the Murrumbidgee River at Gundagai, designed by William Christopher Bennett and built from 1864 to 1867 by Francis Bell. The remaining structure consists of the iron truss spans over the river and a few timber spans at each end; most of the timber beam approach across the floodplain has been demolished. The iron bridge is owned by Transport for NSW.

The Prince Alfred Bridge opened on 24 October 1867, named for Queen Victoria's second son, Prince Alfred, who was touring Australia that year. It was the first metal truss bridge built in New South Wales, designed by William Christopher Bennett using the Warren and Kennard patent and erected by Francis Bell. The long timber viaduct across the floodplain was completed in 1869.

The bridge marks a key crossing point between the river's two banks and shapes the local landscape of Gundagai to this day. It demonstrates how early settlers had to overcome the waterway to link their communities together.

Access to the structure is available from both sides of the river and the roadway remains open for local traffic. A visit is best made during daylight when you can observe the construction and river landscape below.

The structure's piers were manufactured from cast iron produced at Fitzroy Iron Works in Mittagong. This represents an early example of iron production in Australia and how industry at that time worked together to realize such a large project.
