TheHarlem River is an 8-mile (13 km)tidal strait inNew York City, flowing between theHudson River and theEast River and separating the island ofManhattan fromthe Bronx on the United States mainland.
The northern stretch, also called theSpuyten Duyvil ("spewing devil") Creek, has been significantly altered for navigation purposes. Originally it curved around the north ofMarble Hill, but in 1895 theHarlem Ship Canal was dug between Manhattan and Marble Hill, and in 1914 the original course was filled in.
Harlem River Drive andHarlem River Greenway run along the west bank of the river, and theMetro-North Railroad'sHudson Line andMajor Deegan Expressway on the east.

The Harlem River was the traditionalrowing course for New York, analogous to theCharles River inBoston and theSchuylkill River inPhiladelphia. On the Harlem's banks is the boathouse for theColumbia University crew, and the river is the home course for the university's crew. Since 1952, a large flat rock face, called the "(Big) C Rock" has been painted with Columbia's varsity "C".[1] Also on the river are the Peter Jay Sharp Boathouse and Harlem River Community Rowing, two community rowing facilities. The river is used by crews fromNew York University,Fordham University, andManhattan University, though the only university with permanent facilities on the river is Columbia.[citation needed]
Historically, the west bank of the Harlem River was also an amusement destination. The area between 190th and 192nd Streets was occupied by theFort George Amusement Park, atrolley park/amusement park, from 1895 to 1914. Its site is now a seating area inHighbridge Park.[2] In the 1890s, the City of New York built a racetrack for horses, theHarlem River Speedway, along the riverbank of the park;[3] the project started construction in 1894[4] and opened in July 1898.[5] The Speedway later became the Harlem River Drive, and regular motorists were first allowed on the drive in 1919.[6]
The Harlem River is spanned by seven swing bridges, four lift bridges, and four arch bridges,[7] and is navigable to any boat with less than 55 feet (17 m) ofair draft. However, any boat requiring more than 5 feet (1.5 m) of clearance will require theSpuyten Duyvil Bridge to swing open. All other movable bridges on the Harlem River provide at least 24 feet (7.3 m) of clearance while closed, so boats and ships requiring between 5 and 24 feet (1.5 and 7.3 m) of clearance need only have one bridge swing open. These bridges replaced fixed bridges or lower bridges in the late 19th century to improve navigation.High Bridge was erected between 1837 and 1848 to carry theCroton Aqueduct across the river. It is the oldest bridge in New York City.
TheNew York City Department of Transportation advises that while they make every effort to ensure that all bridges are operating, many of them are under repair at any time, and outside contractors are responsible for opening of bridges under repair.
