Vision will route traffic based on a design speed of design 60km / h lane two-way roads, the route length of 3666.11 meters, roadbed width of 10 meters, a total of five horizontal curve, five vertical curve. Section of the route, including plan, profile and cross-sectional design. First carried out on paper alignment and correction-oriented line drawing, by comparison to determine the optimal solution; Secondly, according to plane combines local topography, climate, environmental factors were longitudinal design; finally selected 1km conduct cross-sectional design and draw cross-sectional diagram, calculate the earthwork. Subgrade superelevation and widening considered in the design calculations and design for the drainage protec
