New York State Route 27 is a state highway on Long Island connecting New York City with Suffolk County destinations including Hempstead, Huntington, Patchogue, Riverhead, and Montauk Point. The route incorporates arterial streets, parkways, and expressways traversing urban, suburban, and coastal landscapes between Manhattan and the Atlantic Ocean. It serves as a primary corridor for commuters, freight, and tourism to attractions such as Jones Beach State Park, Fire Island, Robert Moses State Park, and numerous Long Island Rail Road stations.
Route description
The corridor begins near Schenectady-style urban grids in New York City boroughs, transitioning to the Meadowbrook State Parkway network through Nassau County, skirting landmarks like Flushing Meadows–Corona Park, Citi Field, Belmont Park, and the Cradle of Aviation Museum. Eastward sections run parallel to Sunrise Highway alignments, crossing the Hempstead Plains and intersecting routes serving Garden City, Westbury, Massapequa, and Babylon. The highway meets the Robert Moses Causeway near Great South Bay and provides access to Jones Beach State Park and Westhampton Beach. Further east, it traverses the North Fork-adjacent corridor near Greenport connections before terminating at the fishing and maritime destination of Montauk. The route crosses multiple water crossings and ecological zones including Great South Bay, Shinnecock Bay, and coastal wetlands adjacent to Fire Island National Seashore.
History
Origins of the route date to early 20th-century turnpikes and plank roads that linked Brooklyn to eastern Long Island destinations such as Rockaway and Montauk Lighthouse. The designation was formalized in the 1920s amid statewide renumbering inspired by improvements like the Lincoln Highway and federal highway initiatives tied to Benjamin Strong Jr.-era infrastructure investment. Mid-20th-century construction of expressways and parkways, influenced by planners connected with projects like Robert Moses developments, reshaped alignments through Hempstead, Garden City, and Islip. The rise of automobile culture and suburbanization linked to postwar housing booms in areas such as Levittown and Rockville Centre prompted expansions and interchange reconstructions modeled after Interstate Highway System standards. Environmental and community advocacy by groups associated with Sierra Club and local preservation societies influenced later modifications near Fire Island and Shinnecock Hills, while transportation agencies including the New York State Department of Transportation and regional planning bodies coordinated funding with federal partners such as the United States Department of Transportation.
Major intersections
Key junctions connect the route to regional and national networks, intersecting with limited-access arteries like the Heckscher State Parkway, Southern State Parkway, Northern State Parkway, and Robert Moses Causeway, and with numbered routes including I-495, NY 25, NY 27A, and NY 24. Major interchanges provide links to transportation hubs such as John F. Kennedy International Airport, LaGuardia Airport, and Islip MacArthur Airport, and connect to rail at Hempstead Station, Huntington Station, and Patchogue Station. The corridor intersects municipal centers including Mineola, West Babylon, Sayville, Ridge, and East Hampton. Freight linkages tie into port facilities such as Port of New York and New Jersey terminals and marine services at Montauk Harbor.
Traffic and usage
Traffic patterns reflect commuter flows between Nassau County suburbs and Manhattan employment centers, seasonal tourist surges toward Jones Beach State Park, Montauk Point State Park, and Hamptons communities like East Hampton and Southampton. Peak volumes coincide with holiday weekends and events at venues such as Jones Beach Theater and cultural sites including Long Island Museum of American Art, History, and Carriages. The route supports public transit connections with LIRR services and regional bus operators like Nassau Inter-County Express and Suffolk County Transit, and carries commercial traffic serving Walt Whitman Shops retailers, industrial parks in Deer Park, and distribution centers near Ronkonkoma. Safety initiatives have been influenced by studies from institutions including Cornell University and Columbia University transportation research centers, and funding drawn from programs linked to Federal Highway Administration grants.
Related routes and designations
Auxiliary and former alignments include numbered and named spurs, business routes, and historic turnpikes tied to regional planning documents maintained by the New York State Department of Transportation. Designations such as parkway segments connect to the Southern State Parkway and align with planning frameworks used by the Metropolitan Transportation Authority and Nassau County Planning Commission. Local municipalities maintain connector roads in villages like Garden City South and Hempstead Plains, while county routes in Suffolk County and Nassau County provide parallel alternatives. Preservation and scenic designations have been proposed in coordination with groups including The Nature Conservancy and Preservation Long Island to protect landscapes adjacent to Shinnecock Hills Golf Club and other cultural sites.
