The Atlas Product Spotlight - HO Scale Viaduct
Throughout the history of railroad structural engineering, the viaduct has long been a favored way to cross steep valleys or wide rivers. Consisting of a series of elevated arches or piers supporting a long flat roadbed between two points of roughly the same elevation, classic viaducts were impressive structures made of stone or reinforced concrete construction. Although taking more time to build than a wooden, iron, or steel open frame bridge, masonry viaducts could safely span greater distances and handle greater loading with less maintenance over their lifetimes. Indeed, the longest stone masonry viaduct railroad bridge in the world (at 3820 feet) is the famous Rockville Bridge across the Susquehanna River, which was built in 1902 by the PRR and is still in use with Norfolk Southern. Other stone masonry viaducts still in use include the Santa Ana River Viaduct on the UP and the Starucca Viaduct on the NYS&W.
