Steep Rocky Creek Railway Bridge

Steep Rocky Creek Railway Bridge is a heritage-listed railway bridge on the Mungar - Monto railway line at Ideraway in the North Burnett Region of Queensland, Australia. It was designed by William Pagan and built from 1906 to 1907. It was added to the Queensland Heritage Register on 21 October 1992.

History
Construction of the section from Wetheron to Gayndah began in March 1906 using day labour. The Deep Creek crossing posed engineering difficulties. Completion of the line was delayed building two bridges of special designs over gorges between Ideraway and Gayndah including Steep Rocky Creek (the other being Ideraway Creek Railway Bridge).

Drawings for the bridge were signed by Chief Engineer, William Pagan. It was designed to carry the heaviest locomotives in operation at the time. On-site construction was overseen by Pagan. Construction of the bridge was completed in 1907 and the extension was opened for traffic on 16 December 1907.

Description
Steep Rocky Creek bridge includes one 26 ft RSJ span of three joists, five 28 ft concrete arches and a final 26 ft RSJ span of three joists, supported on six concrete piers and two abutments.
