Parkways in New York State

The majority of parkways in the US state of New York are part of a statewide parkway system owned by several public and private agencies but mostly maintained by the New York State Department of Transportation (NYSDOT). A handful of other roads in the Hudson Valley and on Long Island are also known as parkways but are not part of the state system. The state parkway system introduced the concept of limited-access roads. These highways were not divided and allowed no driveway cuts, but did have intersections for some of the streets they crossed. A small section of the privately financed Long Island Motor Parkway was the first limited-access road to begin operation as a toll road and the first highway to use bridges and overpasses to eliminate intersections.

The individual parkways vary widely in composition. Some, such as the Sprain Brook Parkway, are functionally equivalent to a freeway; others, like Seven Lakes Drive, are a two-lane undivided surface road. The majority of parkways are located in downstate New York, where the state parkway system originated in the early 20th century.

The state's parkway system originally began as a series of then-high-speed (25 miles per hour or 40 kilometres per hour) four-lane roads that were created to provide a scenic way into, out of, and around New York City. The first section of this system opened in 1908. Most of the early roads have been replaced and redesigned to address higher speed requirements and to increase capacity. In later sections north of New York City, the roadways were typically divided by a wide landscaped median and provided service areas along the way that offered fuel and restrooms. Many of these parkways were built by regional agencies such as the Long Island State Park Commission (LISPC), New York City Parks Department, Taconic State Park Commission (TSPC), Westchester County Parks Commission (WCPC), and Palisades Interstate Park Commission (PIPC). Most are now maintained, if not owned, by NYSDOT outside New York City and the New York City Department of Transportation (NYCDOT) within New York City.
