This design is mainly divided into four parts, there are as follows: graphic design, profile design, cross-section design and pavement structure design. The highway design speed is80 kilometers per hour, the route length of meters, designing as four-lane highway with two-way streets, a central median and the width of the roadbed meters, This plane has one bend, the minimum bend radius is270 meters, and 1515 .377 meters maximum length of line. Average longitudinal line of this section percent, and the largest longitudinal is percent, percent minimum longitudinal slope. Four change points in vertical alignment, the minimum vertical curve radius is meters. Were set up six culverts. The road of asphalt concrete pavement, according to standard mend 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 to70 cm.
