The Mianus River Railroad Bridge, also known as the Cos Cob Bridge, is a bascule bridge built in 1904 over the Mianus River, in Greenwich, Connecticut. It was listed on the National Register of Historic Places in 1987.[1] It is operated by the Metro-North Railroad, successor to Conrail, Penn Central, and the New Haven Railroad, which erected it, and is owned by the Connecticut Department of Transportation.

It is a rolling lift type moveable bridge.

It was prefabricated by the American Bridge Company, to replace a previous bridge on the site which was unsafe.[2]

The nearby Cos Cob Railroad Station is also NRHP-listed.

It is one of eight moveable bridges on the Amtrak route through Connecticut surveyed in one multiple property study in 1986.[3] The eight bridges from west to east are: this Mianus River Railroad Bridge, at Cos Cob, built in 1904; Norwalk River Railroad Bridge at South Norwalk, 1896; Saugatuck River Railroad Bridge at Westport, 1905; Pequonnock River Railroad Bridge at Bridgeport, 1902; Housatonic River Railroad Bridge, at Devon, 1905; Connecticut River Railroad Bridge, Old Saybrook-Old Lyme, 1907; Niantic River Bridge, East Lyme-Waterford, 1907; and Thames River Bridge (Amtrak), Groton, built in 1919. The Pequonnock River bridge -- also on Metro-North's New Haven Line, as are the Norwalk, Westport, and Devon bridges -- has since been replaced.
