A swing bridge is a unique type of bridge that rotates horizontally around a fixed point. Synonyms for a swing bridge include turning bridge, pivot bridge, rotary bridge, swivel bridge, revolving bridge, and movable bridge. These bridges are commonly found over canals or rivers, allowing boats and ships to pass through while maintaining the integrity of the bridge. These types of bridges have been used for centuries and continue to be an important form of transportation infrastructure. Whether it's called a swing bridge, turning bridge or any of its synonyms, the function remains the same; the bridge opens up to let vessels pass and closes to allow vehicle and foot traffic to pass over.
