 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.Today, the state parkways are for the most part equivalent to expressways and freeways built in other parts of the country, except for a few oddities.
