The invention discloses an urban T-shaped and crossroad flyover. The flyover system is small in occupied area and low in manufacturing cost, and most urban crossroads at present can be transformed almost without a new land. According to the flyover, an underground passage (culvert) and an overground short bridge erecting mode are adopted, the length and the width of the flyover generally do not exceed 23 meters (four motor vehicle lanes with the width of 3 meters, two non-motor vehicle lanes with the width of 3 meters and two sidewalks with the width of 2 meters), and the length of the flyoveris determined according to the number of lanes. The length of the underground passage is generally the width of the road. An upper passage and a lower passage are adopted for straight movement; a right turn adopts a right turn special lane for passing; and left-turn small vehicles complete passing through the underground culvert, and large vehicles complete passing through three right turns.
城市丁字、十字路口立交桥。本立交系统占地面积小、造价低，现大多城市十字路口几乎不用再新征土地就可改造。本立交桥采用地下通道（涵洞）和地上架短桥方式，桥长和宽一般不超过23米（四条3米宽机动车道+2条3米宽非机动车道+2条2米宽人行道），以使用车道多少确定桥的长度。地下通道长度一般为路的宽度。直行分别采用上通道加下通道通行；右转采用右转专用道通行；左转小型车辆采用地下涵洞完成，大型车辆采用三个右转完成。
