Viaduct

A viaduct is a type of bridge composed of a series of arches or spans used to carry a road or railway across a valley, river, or other low-lying terrain. It provides a smooth, level path over uneven or challenging ground, allowing transportation to continue efficiently. Typically made of materials like concrete or steel, viaducts are designed to support heavy loads and long distances, often featuring multiple supports or piers. They are essential engineering structures that facilitate transportation and connect areas that would otherwise be difficult to access by crossing natural obstacles.
