Definition
A truss bridge is a type of bridge distinguished by its load-bearing superstructure, which uses a truss. A truss is a structure comprising interconnected elements (typically straight) that, most often, are organized into triangular units. These triangular units provide rigidity and stability, distributing weight effectively across the bridge. Unlike suspension bridges that use cables, truss bridges rely on this network of interconnected elements. They are often used where there are constraints on the depth of the bridge or where a long span is needed without intermediate supports. Common materials used in truss bridges include steel and wood 🪵.
