In recent years, China’s rapid development of science and technology, bridge without stent construction process has been innovative. Swing construction across the railway bridge is a more advanced and common technology. This paper introduces the basic principle of swivel construction across the railway bridge and the characteristics of construction technology. Taking the construction of bridge transits on the west expressway across Beijing-Harbin of Qinhuangdao City as an example, this paper introduces the construction technology of swivel bridge and its technical characteristics, China’s cross-rail bridge construction to provide some reference.
