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. In western Nassau County the parkway sports six lanes, three eastbound and three westbound, narrowing to four lanes total in central Nassau and through its short distance 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 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.
