What are the advantages of a floating bridge on water?

A floating bridge on water is a kind of simple bridge built on the water surface, usually composed of floating barrels, trestles, etc. It has the following advantages:
 
- Simple construction: Compared with traditional bridges, a floating bridge on water does not require complex foundation construction, reducing large-scale underwater excavation, pouring and other operations. The construction difficulty is low, the speed is fast, and it can save a lot of time and labor costs. For example, in some temporary emergency scenarios, a floating bridge can be quickly built to meet the traffic needs.
 
- Strong adaptability: It can be flexibly adjusted in length, width and shape according to different water conditions and usage requirements. It can adapt to various complex water surface environments. For instance, on rivers and lakes with large water level changes, the floating bridge can rise and fall with the water level to maintain stable traffic capacity.
 
- Low cost: Due to the reduction of foundation engineering construction and the use of large construction equipment, the material cost and construction cost are relatively low. Moreover, when it is no longer needed, it can be dismantled, and the materials can be recycled, further reducing the cost.
 
- Little impact on the environment: During the construction process, the damage to the water ecological environment and the surrounding landforms is relatively small. It will not change the water flow pattern and riverbed structure on a large scale like the construction of traditional bridges, which is conducive to protecting the living environment and ecological balance of aquatic organisms.
 
- Multi-functional use: In addition to serving as a passage for pedestrians and vehicles, it can also be used for water sightseeing, leisure and entertainment. For example, a floating bridge passage can be built to connect a water restaurant, a viewing platform, etc. In some emergency situations, such as flood rescue and material transportation, it can be quickly built as a temporary passage.
