About One Tree Bridge
One Tree Bridge is a heritage-listed timber bridge spanning the Donnelly River in the locality of One Tree Bridge, about 21 kilometres northwest of Manjimup in Western Australia's South West region. Built in 1904 from a single giant karri tree to serve the timber industry, the original bridge is preserved beside its modern replacement. Set within tall karri forest, it is a roadside stop on Vasse Highway known for its engineering history and scenic river setting.
