Mount Spec Road including the bridge was constructed between 1930 and 1936 under the Unemployment Relief Scheme during the Great Depression. The road was constructed in hilly terrain by a large labour force using limited mechanical assistance.
The Little Crystal Creek Bridge comprises a single span arch, constructed of concrete but faced with stone. It spans the Little Crystal Creek Gorge in a picturesque location in Paluma Range National Park. A masonry arch design of the bridge has been recommended by the District Engineer Townsville, from the aesthetic point of view, on 8 June 1931. The variation was approved in January 1932 and the construction completed by June 1933. Wages for four stonemasons employed during the construction of the bridge and "too much work dressing stone", contributed to the excessive cost of the bridge.
It is the only concrete arch road bridge dressed with stone that remains in service in Queensland. Mt Spec Road and Little Crystal Creek Bridge are listed on the Queensland Heritage Register.
