But because of the weak basis of highway transportation, The road development is uneven around our country and has big disparity when compared with the developed countries. So accelerating the highway construction and road transportation management is the first priority in a longer period of time. This project is a conventional design for Guang Ping Road of Shou county in Anhui province. The content of this design including that determining highway rating according to the traffic and use properties; Route design and comparison and selection according to applications of the natural conditions and the main technical indices ,and then the determination of reasonable route ; Technical design including plane, vertical section , cross section , subgrade and pavement , drainage design and environmental assessment?for the selected scheme . On these basis obtained various obtained graph, tables and the design specification for construction stage. Keywords: Determination of highway grade; Comparison and selection of
