Abstract: With the continuous development of my country's transportation industry, the importance of highways has become increasingly prominent, and highway construction continues to meet the increasing demand for transportation. At present, the scale of highway construction in my country is continuously expanding. When designing highways, it is necessary to attach great importance to the design of structures such as bridges and culverts. Because the construction of bridges and culverts is difficult, in order to improve the quality of the project and solve the problems in the design of highway bridges and culverts in time, it is necessary to formulate corresponding solutions and adopt reasonable design methods to give full play to the role of highways.
