Embodiment 1

[0020] Referring to Fig. 1 , in the present embodiment, above the crossing pavement layer 1, a vertical double-layered viaduct bridged in the north-south direction of the crossing is set, including the lower bridge 4 and the upper bridge 3.

[0021] As shown in Fig. 2 and Fig. 3, the lower deck bridge 4 and the upper deck bridge 3 are all one-way lanes, and the lane directions on the upper deck bridge 3 and the lower deck bridge 4 are opposite.

[0022] As shown in Figure 2, between the left side of the lower deck bridge 4 and the corresponding lane on the east side of the crossing, a left turn lane 5 from east to north and a left turn lane 6 from south to east are arranged at a facade intersection.

[0023] As shown in Fig. 3, between the right side of the upper deck bridge 3 and the corresponding roadway on the right side of the bridge, a left-turn lane 11 from north to west and a left-turn lane 12 from west to south are arranged at a facade intersection.

[0024] As shown i...

Abstract

The superposed overpass for cross road features that it comprises one longitudinal double-layered flyover crossing including one upper layer bridge and one lower layer bridge separately for vehicles in opposite directions, one from-east-to-north left turning bridge and one from-south-to-east left turning bridge on the left side of the lower layer bridge, one from-north-to-west left turning bridge and one from-west-to-south left turning bridge on the right side of the upper layer bridge. The present invention makes vehicles in all directions unblocked.

Description

technical field [0001] The invention relates to a three-dimensional traffic hub exchange center, more specifically to an overpass suitable for crossroads. Background technique: [0002] With the rapid development of the economy, there are more and more vehicles, which put a lot of pressure on the road traffic. In order to relieve the pressure on the traffic, people have built various three-dimensional traffic road bridges. In the prior art, there are butterfly overpasses, lotus overpasses, and elevated overpasses. Although they have played a good role in dredging and shunting the vehicles, they all occupy a large area and are expensive. Moreover, the structure of each bridge is different, especially the left turn problem. The left turn of the vehicle has always been realized by circling to the right. Once the driver who is not familiar with the structure of the overpass gets on the bridge, he will not be able to tell the difference between the south, the east and the north,...
