Mianus River Railroad Bridge

The Mianus River Railroad Bridge is a railway crossing over the Mianus River in Greenwich, Connecticut, featuring several truss spans and a movable bascule mechanism. Multiple sections rest on stone supports, allowing both train traffic and river vessels to pass through the structure.

Built in 1904 by the American Bridge Company, this structure replaced an earlier bridge that had served the same route. It gained recognition on the National Register of Historic Places in 1987 as an important example of railway infrastructure from that era.

The bridge is part of a rail corridor that shaped how people in the Northeast travel between cities, and its design reflects the importance placed on keeping both trains and river traffic moving through this area.

The bridge is best viewed from the southern bank of the Mianus River, where you can see the structure clearly from ground level. The area is accessible during daylight hours, and you may notice trains passing overhead on the Metro-North Railroad that runs through this section daily.

The bridge contains a lifting mechanism that can raise a central section to allow river boats to pass underneath while trains continue moving overhead. This dual-purpose design is one of the fewer examples in the region where rail and water traffic coexist on the same crossing structure.
