The 2nd Zhengzhou Huanghe River Bridge proper is designed as 8×100 m simply-supported tied arch spans of concrete-filled steel tubes over the wide and braided reach in the midstream of Huanghe River. In the construction of the Bridge, the construction scheme of two-side construction trestles plus gantry cranes over piers are used.
