New York State Reference Routes

The Northern State Parkway is a limited-access parkway that runs for approximately 29 miles west-east across the north shore of New York's Long Island. It is unsigned New York State Reference Route 908G.

In western Nassau County the parkway sports six lanes, three eastbound and three westbound, narrowing to four lanes total in central Nassau at the Wantagh Parkway (Exit 33) and through its twelve miles or so in western Suffolk County, where it ends. It was constructed in stages throughout the 1930's and again post-World War II in the late 1940's/early 1950's until it reached its current terminus in Hauppauge in 1965. The Northern State Parkway is an eastern extension of the Grand Central Parkway. It was part of master planner Robert Moses' aggressive road-building campaign and was built as a sister road to the Southern State Parkway. In recent years its design has quickly become dated due to an increase in commuter traffic using the roadway, and numerous improvements have been made (including the widening from four to six lanes in Central Nassau west to the Nassau-Queens line where it becomes the Grand Central) or are still on paper. Like its siblings in the State Parkway system on Long Island, the Hudson Valley, and in New York City, commercial truck traffic is banned from the parkway due to low overpasses. The Long Island Expressway, or L.I.E. as it is locally known, was built later on by Moses to handle truck traffic travelling between New York City and Long Island's famed East End. The LIE runs directly alongside the Northern State in some parts of Nassau County.

[edit] Route Description

[edit] Nassau County

The Northern State Parkway begins at the eastern terminus of the Grand Central Parkway at the Nassau-Queens border near Lake Success. 1/2 mile into Nassau County, the parkway interchanges with Lakeville Road then New Hyde Park Road, the parkway then curves north then back east and runs directly alongside the Long Island Expressway and interchanges with Shelter Rock Road (at this point, the LIE curves north away from the parkway). The parkway continues east and interchanges with Wills Avenue then Roslyn Road. After the Long Island Expressway interchange in Old Westbury, the parkway takes a sharp curve south and widens to eight lanes. Next, the parkway interchages with I.U. Willets Road then Glen Cove Road. After that, the parkway rises to a high grade and enters a directional-T interchange with the Meadowbrook Parkway, at which the parkway narrows to six lanes. The parkway returns to its east-west alignment and transitions to a modern parkway faucility (complete with interstate standard shoulders and new overpasses). The parkway then interchanges with Post Avenue and then goes for 1 mile before entering a trumpet interchange with the Wantagh Parkway, at this point the parkway narrows to four lanes. Immediately after the Wantagh Parkway interchange, the parkway interchanges with Brush Hollow Road. The parkway winds through Hicksville then curves north to run alongside the Long Island Expressway before interchanging with Routes 106/107. Immediately after the interchange, the ramps from the Long Island Expressway merge with the parkway. The parkway continues to wind through Jericho for .75 miles before interchanging with South Oyster Bay Road then straightens out en route to Route 135/Seaford-Oyster Bay Expressway. This tight cloverleaf interchange does not allow movements from the westbound mainline (traffic bound for that exit should use the LIE via exit 37A). The parkway takes a slight curve north and interchanges with Manneto Hill Road then immediately interchanges with the Long Island Expressway in Woodbury. 0.25 miles later, the parkway interchanges with Sunnyside Boulevard.

[edit] Suffolk County

As the parkway enters Suffolk County it takes on a more hilly terrain and thus curves more frequently; in addition, the exit points become more sparse as the parkway winds through the more rural sections of northern Suffolk. The parkway interchanges with Round Swamp Road. The parkway continues with sparse exits, frequent curves, and takes on hilly terrains while interchanging with NY 110, Wolf Hill Road, NY 231, and Commack Road. The parkway then continues into a cloverleaf interchange with the Sagtikos Parkway and Sunken Meadow Parkway (which is the same mainline). The parkway then provides one last interchange with New Highway before finally terminating at NY 454 and becomes NY 347 in Hauppauge.

[edit] Interesting facts

The recently widened stretch of the Northern State Parkway between exits 31A and exit 33 is actually built to modern FHWA Standards though the speed limit remain 55 miles per hour.

Between Exits 38 and 39, the northern terminus of Bethpage State Parkway and southern terminus of Caumsett State Parkway were proposed to have an unconventional interchange at Exits 37A and 37B respectively.

Between Exits 41 and 42 the Dix Hills Road bridge goes over both the parkway and Old Country Road.

Just east of Exits 42 N-S was the proposed Babylon-Northport Expressway interchange.

Three service areas used to exist in widened areas of the median along the Parkway. The first was east of Meadowbrook State Parkway the second was west of Suffolk CR 4 (Commack Road), and the third was at the former terminus of the Northern State Parkway and existing terminus of the Sagtikos State Parkway.

The only evidence of the formerly shared termini of the Northern and Sagtikos State Parkways can be found in what is now the east-to-south ramp of Exit 44, which is wider than the other ramps, as well as those for Exit 45 to the Sunken Meadow State Parkway.

Beyond NY 454, there were plans to extend the Northern State Parkway further east through Caleb Smith State Park Preserve, then along the Nissequogue River. After crossing New York State Route 111, it would have turned south across Long Island until entering Connetquot River State Park Preserve, where it would include additional park entrances, then turn west finally terminating at Heckscher State Parkway between Suffolk CR 17(Carleton Avenue) and New York State Route 27.
