[1] A rail link was requested from Maryborough to the long established town of Gayndah in the 1860s, but construction did not begin until the late 1880s.

[1] The use of concrete arches for railway bridges is a distinctive feature in Queensland and South Australia.

However, Steep Rocky Creek Railway Bridge in 1906 departs completely from stone forms and has wall type arches supporting vertical diaphragms with a deck slab carrying the track and ballast; this bridge was built to cross a ravine in rugged country and represents a similar design and technical developments to meet similar requirements to that at Humphery, which was completed a few years later.

Although a simple bridge, it is well detailed with projecting cornices at the bases of the arches, attached pillars above the piers extending above the deck and recessed spandrel walls.

The smaller end spans spring from a higher level, again marked at the pier by a small cornice.

[4] The Official Register of Engineering Heritage Markers listed Degilbo-Mundubbera Railway Bridges in October 2016.

[5][6] Humphery Railway Bridge was listed on the Queensland Heritage Register on 21 October 1992 having satisfied the following criteria.

It demonstrates the skill with which the technology of the era was used to solve the problems of climatic conditions and terrain encountered by railway engineers in this process.
