beam bridges

A beam bridge is a simple type of bridge made of horizontal beams supported at each end by piers or supports. The main function is to carry the load of traffic or objects across a gap, such as a river or valley. Think of it like a flat plank or plank-like structure extending between two points. The beams bear the weight and transfer it to the supports, which transfer the force to the ground. Beam bridges are most effective when spanning short distances, as longer spans require stronger, more complex designs. They are commonly used for roadways and small crossings due to their straightforward, economical construction.
