摘要： An overpass structure with vertical interchange arrangement for crossroads includes a transverse roadway at a bottom level, a pedestrian walkway in the middle level and a longitudinal road bridge at an upper level. The vehicle roadways on and under the bridge are connected by two ramp units. The pedestrian walkway is a pedestrian platform with an interchange platform provided on top. The interchange platform is located between and connected to two roadways of opposite directions on the longitudinal road bridge in the upper level. The leftmost lane along a forward moving direction of vehicle on the bridge in the longitudinal road bridge is defined as a universal lane of the longitudinal road bridge. The rightmost lane along a forward moving direction of vehicle under the bridge in the transverse roadway is defined as a universal lane of the transverse roadway. The interchange platform is connected to four universal lanes.
