The bridge is also used by Amtrak for its Northeast Corridor services. ==History== The current bridge is the third railroad span in the same location. The original bridge was the first railroad bridge over the Housatonic, and was a single-track wooden structure built in 1832, which was replaced by a double-track cast-iron bridge in 1858 and finally by the existent four-track steel bridge in 1905.〔Images of Stratford, Stratford Historical Society, 1997 p80 ISBN 0-7385-0066-6〕 It was built for the New York, New Haven and Hartford Railroad.
