What is a "beam bridge"?

A beam bridge is a simple type of bridge that consists of a horizontal beam supported at each end by piers or end supports. The weight of the bridge and any loads on it are transferred directly to these supports. Beam bridges are commonly used for short spans and are one of the oldest and most straightforward types of bridge designs. They can be made from various materials, including wood, concrete, or steel, and are often used for roadways or pedestrian paths. The simplicity of their design makes them cost-effective and easy to construct.
