Deck girder bridges are used by prototype railroads more frequently than any other type of bridge. They span everything from ditches to small rivers. These kits include X braces, lateral braces, rivet plates, bridge shoes and extensive molded-in details including rivet heads. The Open Deck Bridges include Bridge Flex-Track while the modeler's regular ballasted track runs across the supplied concrete deck of Ballasted Track Deck Bridges. Kits are less track and ballast.
