The Shinnecock Canal Railroad Bridge (also known as the K4 Bridge) is a railroad bridge carrying the Montauk Branch of the Long Island Rail Road over the Shinnecock Canal in Hampton Bays and Shinnecock Hills, Suffolk County, New York, United States.
The Shinnecock Canal Railroad Bridge stands at a height of approximately 22 feet (6.7 meters) above the water and measures 316 feet (96 meters) in length.[1][2][3][4] The bridge is constructed of steel and uses a truss design.[3][4]
As Pennsylvania Railroad K4 class steam locomotives regularly crossed the bridge following the replacement of the second span, the bridge became commonly known as "K4 Bridge."[4] Prior to the current span's construction, these locomotives were unable to cross the bridge due to their weight.[4]
The bridge's NYSDOT bridge identification number is 7710170.[3]
