Product applications
The overpass realizes the complete separation of pedestrians and traffic flow, the safety of pedestrians is more guaranteed, and the movement of vehicles is more smooth. However, the cost of the overpass is lower and the construction period is shorter, and it will not affect the load-bearing capacity of the road. Now the large overpasses in cities are equipped with elevator installations, which is convenient for the elderly to use.
