A central span bridge, often referred to as a cantilever bridge, features a main span that is supported at each end by cantilevers extending from the bridge's piers. This design allows for long spans without the need for intermediate supports, making it ideal for crossing wide bodies of water or deep valleys. The structure typically includes a balanced design, where the weight and forces are distributed evenly to maintain stability. Central span bridges are often used in various applications, including highways and railways.
