With the continuous development of highway bridge construction in China,the scale of the project continuously expands,which puts forward higher requirements for the selection and design of small-and medium-span bridges.This paper firstly discusses the selection and design of bridges from the perspectives of topographic and geological conditions,height-span relationship and structural form;then discusses the selection and design of the superstructure and the selection and design of the substructure,so as to provide reference for more engineering projects.
