Railways are different from other means of transportation, especially in bridges, which is a special condition in which trains with large loads run parallel along parallel tracks. In the era of high-speed operation, the application of long bridges to bridges is still difficult, and the problems of structural change and long-term deflection and orbital stability due to temperature expansion between trajectories and bridges must be seriously considered. In this paper, we will examine the history of development by bridge type by classifying the conventional railway bridge in the 1990 "s and the modern railway bridge since 1990 before the introduction of the high - speed railway, We propose the development direction of bridges fitted to the above-mentioned high speed railway while maintaining the direction of future railway bridge and existing vehicle and railway system.
