A trestle bridge is a type of bridge that uses a framework of triangular shapes to support its structure. These bridges are typically made of wood or steel and are designed to span long distances while providing stability. The triangular design helps distribute weight evenly, making them strong and efficient for carrying trains or vehicles. Trestle bridges are commonly found in areas with uneven terrain, such as valleys or rivers. They are often used in railroad construction due to their ability to support heavy loads. Their distinctive appearance and engineering design make them an important part of bridge architecture.
