A viaduct is a bridge composed of several small spans. It is built for crossing a valley, dry or wetland, or forming an overpass or flyover.[1][2][3][4][5]

The word viaduct has two parts from Latin: via for road and ducere, to lead. The ancient Romans did not use this word; it was invented in the nineteenth-century by analogy with aqueduct.[4]
