Research methods: Based on the newest design concept for road，the type selection designs are made for the overpass by adopting design software DICAD-PRO for interchange overpass programmed by Liu Hong-bo of East Southern University.
Research results: In the design of the overpass in city the sectors of volume of traffic，surrounding surface features， travel safety，removal requisition of land，landscape requirement and construction scheme should be taken into account for the coordination of the function，safety and style with the investment. This overpass design is tight design for beautiful bridge in style，which coordinates with raising spiritual outlook of Shijiazhuang.
Research conclusions: The design of overpass in city should closely aim at the surrounding buildings and site conditions and make reasonable use of the space to arrange the overpass with meeting the functional requirements. The bridge should be designed in humanization with good directional identification marking , so the traffic analysis is a very important basis. The reasonable technological standards should be used for better control of the scale of overpass and the overpass with rational structure，beautiful style and suitable construction scheme should be selected.
