[Abstract]：

The starting point of the express highway design from Wuhan city to Ma city ,Hubei province ，is Changti village, Sanli town ,and the superhighway ends in Xiajiagang village, which connects to Huanggang section of the highway. The section of the highway from  K1+600 to K4+700 is selected to design, which is 3.1 kilometers long. According to the route project of construction documents design phase, the whole line adopts superhighway standard of two－way traffic and four lanes. The designed velocity of the highway is 100 km/h, and the roadbed width is 26.0 m, The designed load of the bridge adopts highway-Ⅰ-grade,and the width of the bridge is the same as the highway. The main contents of the project include the plain design, the vertical section design, the cross section design, the protection engineering design(the retaining wall of gravity ), the road surface design(Asphalt Concrete Pavement) and bridge design。  Among them, the calculation and painting of flat design, vertical section design, cross section design, the protection engineering design are designed by handicraft .The design of road surface structure ，the calculation of the thickness of the road surface and checking computations of the tensile stress adopt the design system of the highway road surface structure--- HSP2000.And the bridge engineering adopts bridge structure analysis software BSAS to design.
