Bridge carrying US 1 over the Housatonic River consisting of five open-spandrel concrete arches and a double-leaf arched Pratt deck truss bascule span.

The bascule type is a fixed trunnion. It is NOT a Brown type bascule. According to the NRHP Nomination "In the Proceedings of the Connecticut Society of Civil Engineers, Deputy State Highway Commissioner Richard L. Saunders described the bascule as a "Brown type." Although the bridge does not embody any of the specific bascule patents held by Thomas E. Brown, the mention of his name suggests that Waddell involved him in the design as a subconsultant." It is not known what (if any) involvement Brown had with this bridge, however again this is NOT the unusual "Brown" type bascule, and is the much more common fixed trunnion type of bascule, which was popularized in Chicago and sometimes called the Chicago type as a result.
