Why Hudson River Greenway matters.
Hudson River Greenway is a continuous waterfront corridor where Manhattan's West Side meets separated cycling infrastructure, linear parkland and a Hudson River shoreline reclaimed from generations of transportation and industrial use.
Set along Manhattan's western edge beside Route 9A near Chelsea and just steps from Chelsea Waterside Park, the greenway occupies a narrow north-south band between the city street network and a waterfront extending toward New York Harbor. A paved two-way bikeway forms the principal movement corridor through Hudson River Park, with landscaped buffers separating bicycles from motor traffic and pedestrian areas positioned closer to the river across substantial portions of the route. Long straightaways alternate with crossings, planting beds and connections into successive waterfront sections, allowing the corridor to shift physically as Manhattan's shoreline changes from Lower Manhattan through Greenwich Village, Chelsea and Hell's Kitchen. Its alignment also links the waterfront park system with routes continuing north toward Riverside Park and south through Battery Park City, giving the West Side a sustained nonmotorized axis across much of Manhattan. The result is an unusually extensive piece of transportation infrastructure whose separated pavement, landscaped edges, riverfront connections and long uninterrupted alignment bind numerous West Side districts into one continuous waterfront route.
What defines Hudson River Greenway.
Hudson River Greenway is best known for converting the transportation corridor beside Manhattan's post-industrial Hudson waterfront into a continuous cycling and walking connection developed alongside the reconstruction of Route 9A. New York City's 1993 Greenway Plan supplied an important planning foundation for the route, and the Hudson River Greenway was subsequently constructed in conjunction with the Route 9A rebuilding program. That undertaking followed the failure of Westway, the immense highway proposal that had dominated debate over Manhattan's western waterfront before its collapse created an opening for another approach to the shoreline. By 1986, the governor and mayor had formed a joint city-state entity to coordinate planning for Route 9A and the future West Side waterfront, accompanied by an advisory committee representing communities, labor, environmental groups and other constituencies. Thirteen years of planning helped shape the concept of an urban boulevard beside a new waterfront park, linking transportation reconstruction with public access to land left behind by the decline of maritime commerce. New York State began rebuilding the five-mile Route 9A corridor from Battery Place to West 59th Street in 1995, replacing the remnants of the former elevated West Side Highway with an at-grade, heavily landscaped boulevard. The Hudson River Park Act followed in 1998, creating Hudson River Park on state and city land and establishing the Hudson River Park Trust after years of environmental review and waterfront advocacy. Construction on the bikeway and walkway advanced with Route 9A 2000, when some sections already had permanent separated paths and other stretches still relied on narrow temporary alignments bordered by concrete barriers and chain-link fencing. The completed corridor joined roadway reconstruction, nonmotorized transportation and waterfront access within one of Manhattan's largest late twentieth-century infrastructure changes.
The World Trade Center attacks created a second major chapter in the greenway's development when destruction and recovery operations severely damaged Route 9A through Lower Manhattan. Two northbound roadway lanes within the exposed World Trade Center slurry wall disappeared, and New York State constructed a temporary six-lane roadway that opened on March 29, 2002 to restore the crucial West Side connection. A supplemental environmental review between 2003 and 2004 preceded a 2005 decision to rebuild eight traffic lanes and shift the highway westward around the slurry wall. That reconstruction also retained continuous bicycle and pedestrian infrastructure, with plans specifying a bikeway generally 16 feet wide and landscaped separation between active transportation, motor traffic and the parallel walkway. West Street Promenade South opened between West Thames Street and Battery Place in July 2006 after an 18-month construction campaign that added 200 trees, more than 7,000 shrubs and expanded pedestrian areas. The larger Route 9A corridor now functions as a six- to eight-lane urban arterial accompanied by a continuous Class I bikeway and walkway between Battery Place and West 59th Street. New York State retains ownership of the bikeway beside Hudson River Park, distinguishing the transportation route institutionally from the parkland through which much of it passes. A later project between West 57th and West 59th streets strengthened the connection among Hudson River Park, Riverside Park South and the Empire State Trail, extending the greenway's role from a West Side waterfront route into a larger regional trail system.
How Hudson River Greenway fits.
Hudson River Greenway works as the anchor for a waterfront outing connecting ecological reconstruction, the buried geography of Manhattan's former shoreline and the maritime infrastructure that once transferred railroad freight directly across the Hudson.
Begin at Pier 26, where OLIN designed a 2.5-acre Tribeca landscape organized around the ecological conditions that preceded intensive development of Manhattan's shoreline. Five native zones move through woodland forest, coastal grassland, maritime scrub, rocky tidal terrain and the Hudson River, culminating at a 15,000-square-foot Tide Deck engineered as a rocky salt marsh with native shrubs, trees and grasses. The $37.7 million project drew funding from the Lower Manhattan Development Corporation, Citi, New York City and several state agencies before opening on September 30, 2020, becoming Hudson River Park's first new pier in a decade and a major component of Lower Manhattan's post-September 11 waterfront reconstruction. Continue to Gansevoort Peninsula, where the surviving block of 13th Avenue preserves evidence of a Manhattan shoreline once extended farther into the Hudson. The avenue originally ran north from Bloomfield Street toward 23rd Street before waterfront land was excavated so increasingly long ships would remain inside the federal pierhead line. James Corner Field Operations began designing the 5.5-acre parkland in 2019, incorporating the remnant street into a project with a salt marsh, resilient rocky beach and submerged oyster habitat. The site carries still deeper history: Fort Gansevoort stood there beginning in 1808, and Herman Melville later worked at the Gansevoort wharf as a customs inspector. Conclude at Pier 66a, where a restored Baltimore & Ohio Railroad float transfer bridge preserves the freight system that once joined Manhattan directly to railroad networks across the Hudson. Railcars arrived by barge from New Jersey and crossed adjustable float bridges engineered to rise and fall with the tides before continuing along tracks to nearby warehouses, a system that remained active into the early 1970s. The surviving structure stands near the former B&O terminal warehouse on West 26th Street and beside a historic Delaware, Lackawanna and Western Railroad car float, preserving both the shore-side machinery and vessel type used for cross-harbor freight. The progression moves from OLIN's reconstruction of native Hudson ecology through Gansevoort Peninsula's surviving fragment of a vanished Manhattan avenue and culminates at the railroad float bridge, tracing how natural shoreline, reclaimed land and industrial transportation successively reshaped the western edge of Manhattan.
