Significance
Criterion AThe place is important in demonstrating the evolution or pattern of Queensland’s history.
The deck-type pin-jointed fishbelly truss main span is unique in Australia. It is the only bridge of its type in Queensland and therefore the longest span of its type in Queensland. It innovatively re-uses the falsework of the Burdekin River Bridge at Macrossan of 1899 (This falsework had been re-used on two separate bridges prior to this one).
The bridge demonstrates the economies employed in the construction of Queensland's railways.
Criterion BThe place demonstrates rare, uncommon or endangered aspects of Queensland’s cultural heritage.
The deck-type pin-jointed fishbelly truss main span is unique in Australia. It is the only bridge of its type in Queensland and therefore the longest span of its type in Queensland.
Criterion FThe place is important in demonstrating a high degree of creative or technical achievement at a particular period.
It innovatively re-uses the falsework of the Burdekin River Bridge at Macrossan of 1899 (This falsework had been re-used on two separate bridges prior to this one).
The bridge demonstrates the economies employed in the construction of Queensland's railways.
Criterion HThe place has a special association with the life or work of a particular person, group or organisation of importance in Queensland’s history.

History
Construction of the section from Wetheron to Gayndah began in March 1906 using day labour. Completion of the line was delayed building two bridges of special designs over gorges between Ideraway and Gayndah. The Ideraway Creek bridge was designed and drawings signed by Chief Engineer, William Pagan, on 10 December 1906. The extension was opened for traffic on 16 December 1907.
Description
The Ideraway Creek bridge is one of the most unusual bridges in Australia. It demonstrates the economic re-use of part of the erection truss used to build the Burdekin River bridge at Macrossan between Townsville and Charters Towers opened in 1899. The complete truss was 250 foot long whereas the Ideraway Creek bridge uses only 150 foot of the span. The pinned construction and multiple members of the truss were originally designed for rapid assembley and disassembley.
