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.
