The Lamington Bridge, which crosses the Mary River from Tinana to Maryborough, was built to the design of AB Brady and opened in 1896.

[1] The port of Maryborough was established in the late 1840s to supply sheep stations on the Burnett River and provide an outlet for their wool.

The establishment of manufacturing plants and primary industries sustained its growth as a major regional centre.

During the disastrous floods of 1893, this bridge was partially demolished, cutting off the important road that linked Gympie to the port.

[1] Brady was born and trained in England, designed many notable bridges and was one of Queensland's most important early engineers.

[1] In discussing his very early choice of concrete for the Lamington Bridge, Brady explained that "the Author was induced to recommend a concrete bridge, as it ensures a structure of very great strength, almost everlasting in character, and the annual expenditure in maintenance is consequently reduced to a minimum".

Brady wrote a detailed account of the design and construction of Lamington Bridge in a paper he presented to the Institute of Engineers in 1900.

The bridge was opened to traffic on 30 October 1896 by David Hay Dalrymple, MLA, Minister for Public Works.

The bridge is reinforced on both faces with eleven rails, which were erected as frames and are bolted to the pier tops underneath the concrete and spliced with fishplates.

The reinforcement consists of railway rails 92 millimetres (3.6 in) deep, with 82.6 metres (271 ft) long lower flanges.
