Bridges play an important role for humanity. Their presence reduces the time spent on the road, allowing you to overcome obstacles (rivers, reservoirs, abysses) straight, which is valuable both from an economic and practical point of view.
Bridges are distinguished by two main parameters: the load capacity (railway, automobile, pedestrian, combined) and the static scheme (girder, truss, spacer, pontoon). Below is a list of the longest suspension bridges that belong to the category of spacer systems. Their main difference is considered to be the main load-bearing structure, made of flexible elements that work on tension; thus, the roadway is in a suspended state.
