On the basis of selecting and comparing the overhead crossing program of pipeline, the authors consider that the large or below large scope suspension overhead crossing structure should be adopted in Mulonghe, Mashuihe, Mahuangxi and Yesanhe, the truss overhead crossing structure should be adopted in Daxigou, ^#1 and ^#2 Spot in Huangshuihu. In allusion to the design in the 7 overhead crossings, the optimal selection and improvement on the materials used in structure characteristics, bridge structure and main suspension are carried out.
