Wangcheng Jijiang bridge is located in Wangcheng District, Changsha City, Hunan Province. It spans Jishui river. It is the first prestressed concrete continuous beam bridge constructed by flexible pier multi-point pushing method in China. The bridge is 240m long and 2 × 1.5 + 7 (m) wide. The upper structure is 4 × 38 + 2 × 38 (m) two continuous beams with equal height. The cross section adopts single box and double chambers, and the beam height is 2.5m.
