The Hudson River Greenway

The Hudson River Greenway is the longest greenway in Manhattan, running along the West Side, from Dyckman Street in the north to Battery Park in the south, mostly through Riverside Park and Hudson River Park. A gap in West Harlem was filled in early October 2008 with the opening of the Harlem Piers bike lane. A roughly 10-block detour in the west 80s, where a walkway had crumbled into the river in the late 20th century, was eliminated on May 20, 2010, when the rebuilt section of greenway was opened.

The Hudson River Greenway is the most heavily used bikeway in the United States. The majority of it is close to Hudson River water level, except the portion north of George Washington Bridge where it climbs steeply, to approximately 160 feet (50 m) and includes Inspiration Point.

Near the downtown end, ongoing renovation work on the South Ferry subway station is to result in a connection through Battery Park to the East River Greenway.

Travelers to Brooklyn use a bike lane in Warren Street and a one-way bike path (opened in September 2008) through the north end of City Hall Park to connect to the Brooklyn Bridge. Those arriving from Brooklyn use lanes in Park Row and Murray Street to reach the Greenway.

Footpaths continue a mile north from Dyckman Street into Inwood Hill Park alongside the western ball fields, at which point the path crosses the Amtrak rail tracks using a bridge with steps. This continues northeast into the park as part of the park trail system and connects north to bikeways in Spuyten Duyvil in the Bronx via the Henry Hudson Bridge, and east to the bike lane on 218th St leading to the Broadway Bridge. However, Inwood Hill Park currently bans bicycles on all paths so the connections are not technically recognized nor officially encouraged at this time.
