This design is mainly divided into four parts, there are as follows: graphic design, profile design, crosssection design and pavement structure design. The highway design speed is 80 kilometers per hour, the route length of , designing as fourlane highway with twoway streets, a central median and the width of the roadbed is meters, This plane has one bend, the minimum bend radius is270meters, and meters maximum length of line. Average longitudinal line of this section is percent, and the largest longitudinal is , minimum longitudinal slope. Four change points in vertical alignment, the minimum vertical curve radius meters. Were set up six culverts. The road of asphalt concrete pavement, according to standard remend structure level 15 cm set asphalt concrete type do facing, 20 cm cement stabilized macadam and 35 cm lime soil do the grassroots, total ply pad to 70 cm.
