Context: The Southern State Parkway (also known as the Southern State or Southern Parkway) is a 25.53 mi limited-access highway on Long Island, New York, in the United States.  The parkway begins at an interchange with the Belt and Cross Island parkways in Elmont, in Nassau County, and travels east to an interchange with the Sagtikos State Parkway in West Islip, Suffolk County, where it becomes the Heckscher State Parkway.  The Southern State Parkway comprises the western portion of unsigned New York State Route 908M (NY 908M), with the Heckscher Parkway occupying the eastern section. New York State Route 27 (NY 27) is an east–west 120.58 mi long state highway extending from Interstate 278 (I-278) in the New York City borough of Brooklyn to Montauk Point State Park on Long Island, New York, in the United States.  Its two most prominent components are Sunrise Highway and Montauk Highway, the latter of which includes the Montauk Point State Parkway.  East of the interchange with the Heckscher State Parkway in Islip Terrace, NY 27 acts as the primary east–west highway on southern Long Island.  The entire route in Suffolk, Nassau, and Queens counties was designated by the New York State Senate as the POW/MIA Memorial Highway.  Every town on the South Shore is accessible through Sunrise Highway.  The service roads that parallel the highway from Farmingdale to Brookhaven are officially designated, but not signed, as New York State Route 906C and New York State Route 906D. The Northern State Parkway (also known as the Northern State or Northern Parkway) is a 28.88 mi limited-access state parkway on Long Island in the U.S. state of New York.  The western terminus is at the Queens–Nassau County line, where the parkway continues westward into New York City as the Grand Central Parkway.  The eastern terminus is at New York State Route 347 (NY 347) and NY 454 in Hauppauge.  The parkway is designated New York State Route 908G (NY 908G), an unsigned reference route.  As its name implies, the parkway services communities along the northern half of the island. The Heckscher State Parkway (formerly known as the Heckscher Spur) is an 8.24 mi parkway on Long Island, New York, in the United States.  The parkway, located entirely within the Suffolk County town of Islip, begins at the south end of the Sagtikos State Parkway in West Islip, from where it continues west as the Southern State Parkway.  It proceeds east as a six-lane parkway through Brentwood and Central Islip, loosely paralleling New York State Route 27 (NY 27).  At Islip Terrace, the Heckscher Parkway turns southward, crossing NY 27 before ending at the toll barrier for Heckscher State Park in Great River.  The parkway comprises the eastern portion of New York State Route 908M (NY 908M), an unsigned reference route, with the Southern State Parkway occupying the western section.  In order to avoid confusion, the highway is signed as an extension of the Southern State Parkway west of the NY 27 interchange (exit 44).

The parkway, which continues north, is a northern spur of the Sagtikos, which opened in September 1952.  The northern end of the parkway is at the toll barrier in exit SM5 in the Kings Park section of Smithtown.  From there, the road continues north through Sunken Meadow State Park to a roundabout at the Long Island Sound.  The parkway comprises the northern half of New York State Route 908K (NY 908K, an unsigned reference route), with the Sagtikos State Parkway forming the southern portion.  Commercial vehicles are, like on most parkways, prohibited from using the Sunken Meadow, except for a portion north of NY 25A in Kings Park.

It is named for the nearby Bronx River, which it parallels.  The southern terminus of the parkway is at Story Avenue near Bruckner Expressway in the Bronx neighborhood of Soundview.  The northern terminus is at the Kensico Circle in North Castle, Westchester County, where the parkway connects to the Taconic State Parkway and, via a short connector, New York State Route 22 (NY 22).  Within the Bronx, the parkway is maintained by the New York State Department of Transportation and is designated New York State Route 907H (NY 907H), an unsigned reference route.  In Westchester County, the parkway is maintained by the Westchester County Department of Public Works and is designated unsigned County Route 9987 (CR 9987). The Sagtikos State Parkway, also known as the Sagtikos or Sagtikos Parkway, known colloquially as "the Sag" is a 5.14 mi north–south limited-access parkway in Suffolk County on Long Island, New York, in the United States.  It begins at an interchange with the Southern and Heckscher state parkways in the hamlet of West Islip and goes north to a large cloverleaf interchange with the Northern State Parkway in the town of Smithtown, where the Sagtikos ends and the road becomes the Sunken Meadow State Parkway.  The parkway comprises the southern half of New York State Route 908K (NY 908K), an unsigned reference route, with the Sunken Meadow State Parkway forming the northern portion.  Commercial vehicles are prohibited from using the Sagtikos State Parkway, a restriction that applies to most parkways in the state.

Construction began in 1927 on this, one of the earliest of the Long Island parkways, with the initial 5 mi segment opening two years later as the Jones Beach Causeway, connecting Merrick Road in Wantagh to newly opened Jones Beach State Park.  The parkway is inventoried by the New York State Department of Transportation (NYSDOT) as New York State Route 908T (NY 908T), an unsigned reference route.

The Meadowbrook Parkway is designated New York State Route 908E (NY 908E), an unsigned reference route.
