The project begins with Long Jingguan (Chengtang Boundary) and ends with Hu Jiadian, via Hujiadian, Jiao longyu, Song zhuangzicun, Yu shundian, Xia dian， Hu luwo,Wei ziyu, Hu zifanzhuang,Xia wopu, end of tiemen guan, with total length of ten kilometers. The roadbed width of the old route is meters and the road width is 7 meters. The proposed project is according to secondary road standard, the roadbed width of which is 10 meters and the road width is meters (Asphalt Concrete Pavement). The major work is the following: Finish the line design, the graphic design, the vertical alignment design, the cross section design and the earthwork calculations by Hint CAD. What is more, plete the subgrade and pavement design based on the line design.
