Abstract The main design is carried on for Jiangsu province first-class highway in this design. The length of this road which we design is 6550m, and the design of the speed is 100km/h, and the road is dual two lane highway and set up the central of separation stip. Fistly, the volume of traffic is carried on the analysis, the corresponding technical specifications are looked up, the grade of the highway and the parameters needed for the design is determined; Secondly, the rout selection is carried on in the horizontal chart, then the plane geometric design is carried on for the rout. In this rout there are three sections of curves which establish transition curve and super elevation. There are five vertical curves in this Profile Design, and which also meet with various requirements of plane surface and vertical surface linear combination design; subsequently, the cross section chart is drawn up after the cross section composition and various elements
