Alfalfa leaf type flyover crossing structure
The invention discloses an alfalfa leaf type flyover crossing structure which comprises a first main trunk road and a second main trunk road, wherein the first main trunk road and the second main trunk road cross. Turn-right ramps are arranged in four quadrants formed by the first main trunk road and the second main trunk road respectively. The alfalfa leaf type flyover crossing structure further comprises four turn-left ramps, and each turn-left ramp stretches over two adjacent quadrants. Each turn-left ramp comprises a turn-left circuitous section and a turn-left annular section; the entrance of each turn-left circuitous section is communicated with the corresponding turn-right ramp where left turning vehicles are driven away, and the exit of corresponding turn-left annular section is communicated with a target lane of the left turning vehicles; each turn-left circuitous section is located on the outer side of the turn-left annular section located in the same quadrant with the turn-left circuitous section. According to the alfalfa leaf type flyover crossing structure, collector-distributor lanes do not need to be arranged; no intersecting section exists between the entrance and the exit of each turn-left ramp, and the traffic capacity of the ramps and mainlines is improved; the alfalfa leaf type flyover crossing structure is slightly lower than an alfalfa leaf type flyover crossing structure provided with collector-distributor lanes in the aspects of land occupancy, building height and project building cost.
