Reasonable design for Huanghe River Bridge in Qileng is particularly critical for its important transport position. The article mainly introduces the bridge site survey, overall design, comparison and se-lection method of bridge scheme and the conclusion and the corresponding type of bridge construction points etc.. After comprehensive comparison, considering the factor of bridge site construction conditions, route, the overall design, the bridge structure parameters, construction technology, construction relocation costs and other aspects, it uses the method of variable cross-section prestressed concrete continuous rigid frame bridge. The design ideas and scheme of the article can provide reference for similar bridge engineer-ing design.
