Riverside Avenue Bridge, Riverside Avenue over Northeast Corridor Railroad right-of-way, Greenwich, Fairfield County, CT

Significance: Riverside Avenue Bridge is one of but a handful of cast-iron truss bridges still in use. Designed by F.C. Lowthorp and built by Keystone Bridge Company in 1871, the structure was originally part of a six-span, double-track bridge over the Housatonic River in Stratford, Connecticut. That bridge was replaced in 1884 and some ten years later this single span was re-erected near Riverside Station in Greenwich.
