Possibly the oldest existing arch bridge is the in Greece from about 1300 BC. The stone bridge is still used by the local populace. The well-preserved has. Stone, brick and other such materials are strong in and somewhat so in, but cannot resist much force in. As a result, masonry arch bridges are designed to be constantly under compressio.
