Saltwater Creek Railway Bridge

Saltwater Creek Railway Bridge is a heritage-listed railway bridge over Bundaberg Creek (also known as Saltwater Creek) on Quay Street from Bundaberg Central to Bundaberg East in Bundaberg, Bundaberg Region, Queensland, Australia. It was built in 1894 by James Overend. It is also known as Millaquin Bridge. It was added to the Queensland Heritage Register on 21 October 1992.

History
Agitation for a railway from Bundaberg to the Woongarra district began in the 1880s and a line was surveyed during 1889-91. In the absence of funds for government construction and with the support of the railway commissioners, Robert Cran of the Millaquin sugar refinery near Bundaberg, was authorised by an Act of Parliament in 1892, to construct a private railway from Bundaberg to the sugar refinery. Plans were prepared for the bridge in 1893. Tenders were called by the government and a contract for construction was awarded to James Overend in January 1894. The railway was opened for traffic on 9 July 1894.

The railway was acquired by the Queensland Government on 3 December 1912. In 1917, an Act of Parliament approved the acquisition of the railway to Woongarra. In 1918, the State Government acquired the extension of the railway which had been constructed by the Woongarra Shire Council.

In 1965, plans were prepared for strengthening the bridge with steel girders suitable for a 12-ton axle loading. This was subsequently undertaken with re-used girders from the Gold Coast.
