Lockyer Creek Railway Bridge is a heritage-listed railway bridge on the Brisbane Valley railway line at Clarendon, Somerset Region, Queensland, Australia. It was designed by Henry Charles Stanley and built from 1885 to 1886 by H A Brigg. It was added to the Queensland Heritage Register on 21 October 1992. == History == The second section of the Brisbane Valley Branch line from Lowood to Esk was let on contract to H. A. Brigg on 2 December 1884 for £57,821. The line was opened for traffic between Lowood and Esk on 9 August 1886.〔 Operating the Brisbane Valley Branch was expensive because the light standard of the line limited engines to B15 standard. As there were many heavy grades on the line, more powerful locomotives could produce substantial savings in the number of trains needed. Using Great Depression relief labour to reduce the cost, strengthening the line to C16 and C17 standard was completed between 1931 and 1933. In 1932 a central timber pier was added to strengthen the 100 foot lattice girder span.〔 In 1968 in preparation for the operation of 60 ton diesel engine locomotives in both single and multiple operation, the longitudinal members were strengthened by the addition of 6x3 inch channels along each side and 9x5 inch transoms laid over the top. The timber piers supporting the 100 foot span were provided with concrete bases. The railway closed for traffic in March 1993.〔
