A viaduct is a specific type of 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.

The Peachtree Arcade was a shopping arcade in downtown Atlanta, Georgia, United States. The building, modeled after the Arcade in Cleveland, was designed by Atlanta-based architect A. Ten Eyck Brown and was located between Peachtree Street and Broad Street near Five Points. Construction began in 1917 and was completed the following year. Located in the city's central business district, it was very popular with citizens, functioning as an unofficial "civic center" for the city. However, by the 1960s, the arcade was facing increased competition from shopping malls located in Atlanta's suburbs, and in 1964, the building was demolished to make way for the First National Bank Building, a skyscraper that, at the time of its construction, was the tallest building in both Atlanta and the southeastern United States. In 1993, the American Institute of Architects named the building as one of Atlanta's most notable landmarks to have been destroyed.
