Lockyer Creek Railway Bridge is a heritage-listed railway bridge on the Toowoomba–Helidon line, Murphys Creek, Queensland, Australia. It was designed by William Pagan and built from c. 1910 to 1911. It was added to the Queensland Heritage Register on 21 October 1992.[1]
History
The railway opened for traffic between Helidon and Toowoomba on 1 May 1867. From the 1870s there has been a continuing process of improving the Main Line between Brisbane and Toowoomba because of its importance as a major arterial route. As part of that process, which required the replacement of original bridges to carry heavier loads, construction work began in 1909 on a reinforced concrete arch bridge over Lockyer Creek at 77m 55c immediately following the construction of one at 75m 48c. Design of the innovative bridge was completed and signed by Chief Engineer, William Pagan on 31 March 1910. The bridge and deviation were completed and brought into use on 21 December 1911.[1]
Description
A concrete arch bridge aligned on a straight alignment and carrying a single track on a ballasted deck. Its spans are:[1]
- 2x15 foot (4.6m) reinforced concrete arches, concrete abutment, common concrete piers
- 1x74 foot (22.6m) reinforced concrete arch supporting 2x12 foot (3.7m) and 1x13 foot (4.0m) reinforced concrete spandrel arches, common concrete piers.
- 1x90 foot (27.4m) reinforced concrete arch supporting 2x13 foot (4.0m) and 2x12 foot (3.7m) reinforced concrete spandrel arches, common concrete piers.
- 1x74 foot (22.6m) reinforced concrete arch supporting 1x13 foot (4.0m) and 2x12 foot (3.7m) reinforced concrete spandrel arches, common concrete piers.
- 3x15 foot (4.6m) reinforced concrete arches, common concrete piers, concrete abutment.[1]
The spandrel columns are arranged in pairs, one for each arch rib, with crossbracing in concrete. The arch ribs are parabolic of rectangular section. There is a concrete balustrade. The whole structure is in cast-in-situ concrete.[1]
