History

Scaffolding during construction, 1905

The Mungar-Monto railway line was built only as far as Degilbo before the financial depression of the early 1890s halted the rail construction program. Construction resumed in 1905 under the Railway Department's day labour program. William Pagan was Chief Engineer at the time. Construction began on the Degilbo to Wetheron extension in February 1905. William Pagan inspected the extent of the construction and preparatory work on the Deep Creek bridge in March 1905. The bridge was completed and the line opened by 21 December 1905. Pagan described the bridge in his annual report for that year as "a concrete bridge of somewhat novel design".

The bridge represented a substantial development in concrete arch bridge design. It followed the 33-foot (10 m) spans used in Swansons Rail Bridge on the Main Line near Toowoomba and the 47-foot (14 m) span at Petrie Terrace road overbridge. It was followed by two substantial concrete arch bridges on the Main Line near Lockyer.
