The Sunnyside Railway bridge was part of the New South Wales’ main northern railway line. The line is no longer used and is derelict. The bridge is in disrepair. It’s condition is listed as ‘critical’ by the NSW Office of Environment and Heritage.
The bridge was designed by John Whitton, the then Engineer-in-Chief for Railways in NSW, and built in 1888. It is called a ‘Queen Post viaduct’ construction, built from ironbark hardwood.
