Intersection, where every kinds of traffic merge, commute and pass over, which is the traffic control of management and organization, the key of the urban traffic, which is the difficult and important points of the road design and traffic management, is an important part of the road network. The intersection of Xinhua Road and Jinguang Street is the design object. Firstly, according to the design of traffic, road grades, related specifications and other conditions，the paper gives the preliminary design of the intersections. Secondly, the cross-sectional design of the intersection is designed, including road width selection, calculate the number of lanes and lane width and so on. Thirdly, graphic design for the intersection, including the intersection widening design, the traffic island design and the radius of curbs and so on. Finally, signal timing design is going for, and service level evaluation is conducted.
