A beam bridge is one of the simplest types of bridges, designed to support loads using horizontal beams. These beams rest on vertical supports, called piers, at each end. When weight is applied, the beams experience bending, but they effectively distribute the load to the piers, allowing the bridge to remain stable and safe. Beam bridges are commonly used for short spans, such as crossing small rivers or roads. They are often made from materials like steel or concrete, which provide strength and durability. Their straightforward design makes them cost-effective and easy to construct, making them a popular choice for many engineering projects.
