1. Beam Bridges: Also called girder bridges, they are the most common type of superstructure. They consist of a horizontal beam (girder) supported on piers or abutments at either end.
2. Arch Bridges: These bridges have a curved structure that transfers weight to the abutments or piers at either end. They are often considered more aesthetically pleasing than other types of bridges.
3. Cable-Stayed Bridges: In this type of bridge, a number of cables attached to towers or pylons support the deck. These cables run from the towers to the deck, providing support and stability.
4. Truss Bridges: The superstructure of a truss bridge is made up of a series of interconnected triangles or trusses. The trusses distribute the weight of the bridge evenly, making them a highly efficient design.
5. Suspension Bridges: These bridges have a main cable or cables that are suspended from towers or pylons. The deck of the bridge is then suspended from the main cable(s) by vertical suspender cables, which help distribute the weight of the bridge.
