The Loop Parkway (also known as the Loop) is a 2.65-mile (4.26 km) parkway in Nassau County, New York, in the United States. It serves the barrier islands south of Long Island itself, beginning on Long Beach Barrier Island at an intersection with Lido Boulevard in Point Lookout. From here, it heads generally east–west across Alder and Meadow islands to an interchange with the Meadowbrook State Parkway on Jones Island, a part of Jones Beach State Park located just north of Jones Beach Island. The islands served by the Loop Parkway are separated by narrow channels of water, all of which connect to Jones Inlet.
