Bunbury Bridge was a single-track, timber railway bridge in East Perth in Western Australia. The bridge crossed the Swan River near Claise Brook and was built for passenger and freight traffic to Bunbury on the South Western Railway, and was also part of the Armadale railway line. The bridge was opened as part of the Perth to Bunbury Railway, which was officially opened on 8 September 1893 by Governor Robinson. Following concerns for its safety, a so-called "temporary" replacement bridge was built between 1930 and 1932.
