Wallaby Rocks Bridge, Allan truss bridge over Turon River in New South Wales, Australia

Wallaby Rocks Bridge is an Allan-type timber truss road bridge over the Turon River on Hill End Road near Sofala. It has three timber truss spans of 27.7 metres each, two approach spans at one end and one at the other, giving a total length of 91 metres. The trusses rest on painted twin cast iron cylindrical piers, the approaches on timber trestles, and a post-and-rail timber guard rail runs the full length.

This bridge was built in 1897 by E. Taylor of Balmain as part of the modernization of road infrastructure in New South Wales. It represents the technical advances that allowed engineers to construct durable structures that could span rivers and connect isolated communities.

This bridge belongs to a select group of remaining Allan trusses in the region and demonstrates a construction method that was particularly common in New South Wales during that era. Visitors can observe the characteristic timber framework and cast iron supports up close.

The single narrow lane means only one direction of traffic can pass at a time, so travelers should expect to wait or yield depending on conditions. It is best to visit during daylight hours and watch for oncoming traffic when crossing.

In 1998, 38 of the 105 Allan trusses built in New South Wales survived, alongside 82 timber truss road bridges from over 400 constructed. The Wallaby Rocks Bridge is assessed as State significant mainly for its technical and historical value, and its iron cylinder piers are noted as a rare technical and aesthetic feature.
