river bridge

A river bridge is a structure that spans across a river, allowing vehicles, pedestrians, or trains to pass from one side to the other without disturbing the waterway. It is built using materials like steel, concrete, or a combination, and is designed to withstand the forces of water flow, weather, and load. Bridges vary in design—such as beam, arch, suspension, or cable-stayed—depending on factors like span length and terrain. They facilitate transportation, connect communities, and support commerce, all while ensuring safety and durability in diverse conditions.
