Route design total length of 3635.582 m, setting up a synthetic curve and two reverse curve, circular curve radius is 800 m, easement curve are 90 m. All of the four vertical curve, the curve radius, respectively is 10000 m, 9000 m, 6000 m and 5000 m. This road is a secondary highway, the design speed of 60 km/h, according to the design specification, selection of single two-lane, unilateral lane width is 3.5 m, setting up the hard shoulder (0.75 m) and the dirt road shoulder (0.75 m), the road a total width of 10 m. One lane width is 3.5 m, setting up the hard shoulder (0.75 m) and the dirt road shoulder (0.75 m), the road a total width of 10 m. Route of excavation slope is 1-0. 5, fill slope of 1:1. 5. In the whole road slope stability all meet the requirements, in a fill more than 8 m location (K1 + 200 - K1 + 400 and K2 + 400 - K2 + 500) set the gravity retaining wall. Pavement with asphalt concrete pavement, pavement structure layer with asphalt concrete (13 cm), using lime fl
