High-speed rail provides a safe, efficient, and economic transportation system for regions with high populationdensity such as eastern China. To accommodate the rapid development of high-speed rails in China, the bridgeswith standard spans have been identified as the main infrastructure type. This article provides a state-of-the-art reviewon the design and construction of the standard simply-supported beam (simple beam) bridges for high-speed rails inChina. The structural components discussed include the main girder, deck, and substructure. The live load models, deformationlimiting values, and construction methods for the bridges are also discussed. Additionally, the experimentaltests were conducted to verify the static and dynamic performances of the structure. The main objective of this paperis to provide the latest design and construction experience of Chinese standard simple beam bridges in high-speed railand show how a quick and quality engineering has been achieved by utilizing these standardized bridges.
