Smooth transition of Jingjiu Railway Bridge on Jinshi Expressway

A few days ago, the main bridge of the separation overpass over Beijing Jiulong Railway on the Tianjin Shijiazhuang Expressway (from Tianjin Hebei boundary to Baoshi boundary) successfully turned. The whole process took 40 minutes, and the turning was accurate and in place. In order to reduce the influence of bridge construction on railway operation, T-structure construction adopts the method of "building first, then transferring". After one-time transferring successfully, it is unnecessary to carry out concrete pouring construction above the railway line, so as to minimize the interference on railway traffic. The separated flyover project across Beijing Jiulong Railway of Tianjin Shijiazhuang Expressway (from Tianjin Hebei boundary to Baoshi boundary) is located in the south of donglingcheng village, Renqiu section of Tianjin Shijiazhuang expressway. It is one of the key control projects of Tianjin Shijiazhuang Expressway and the only transition bridge in the whole line.
