Concrete arch bridge

A concrete arch bridge is a type of bridge that uses a curved structure, called an arch, made from concrete to support loads. The arch naturally directs the weight downward and outward, transferring the force to the supporting pillars or abutments at each end. This design efficiently distributes the weight, allowing the bridge to span large distances without needing extensive supports in the middle. Reinforced concrete enhances the arch's strength and durability, making it suitable for various spans and load conditions. Overall, concrete arch bridges combine elegant curves with solid engineering to create stable, long-lasting crossings.
