The Mianus River Railroad Bridge, also known as the Cos Cob Bridge, is a bascule drawbridge built in 1904 over the Mianus River, in Greenwich, Connecticut. It was listed on the National Register of Historic Places in 1987.[1] The bridge carries the Northeast Corridor, the busiest rail line in the United States, both in terms of ridership and service frequency.[2][3] It is operated by the Metro-North Railroad, successor to Conrail, Penn Central, and the New York, New Haven and Hartford Railroad, which erected it, and is owned by the Connecticut Department of Transportation.

It is a rolling lift type

deck truss spans, while the others are deck girder spans, all set on stone abutments. The main movable span is 107 feet (33 m) long; four of the truss spans are 120 feet (37 m) in length.[4]
