viaduct
Sign in to saveA viaduct is a bridge that consists of a series of arches, piers or columns supporting a long elevated railway or road. Typically a viaduct connects two points of roughly equal elevation, allowing direct overpass across a wide valley, road, river, or other low-lying terrain features and obstacles. The term viaduct is derived from the Latin via meaning "road", and ducere meaning "to lead". It is a 19th-century derivation from an analogy with ancient Roman aqueducts. Like the Roman aqueducts, many early viaducts comprised a series of arches of roughly equal length.
AI overview
A viaduct is a long elevated bridge made up of a series of arches, piers, or columns that carries a railway or road across valleys, rivers, or other obstacles while connecting two points at roughly equal heights. The structure allows traffic to pass directly over terrain features that would otherwise block the way, and the name comes from Latin words meaning "road" and "to lead."
