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.
