A swing bridge is a type of movable bridge that rotates horizontally around a central pivot point to allow boats and ships to pass through. This design is particularly useful in areas where a fixed bridge would obstruct water traffic. Swing bridges can be found in various locations, often spanning rivers or canals. These bridges are typically operated using electric or hydraulic systems, making it easier to open and close them as needed. Engineers design swing bridges to ensure they can support vehicle and pedestrian traffic while also providing sufficient clearance for vessels.
