Bridge supports are structures that hold up a bridge, ensuring it remains stable and safe for vehicles and pedestrians. They can be made from various materials, such as concrete, steel, or wood, and are designed to bear the weight of the bridge and any loads it carries. Common types of supports include piers, abutments, and columns. These supports are strategically placed to distribute weight evenly and prevent the bridge from collapsing. Proper design and construction of bridge supports are crucial for the longevity and safety of the bridge, making them an essential aspect of civil engineering.
