1. What is a viaduct?A viaduct is a long bridge made of many arches or spans that carries roads or trains over valleys, rivers, or cities. It keeps the path at the same height on both ends.
2. Why do viaducts have many arches instead of one big span?Using many arches lets engineers build a very long bridge in pieces, making it easier to support the weight and keep the road level.
