Highway system | |
Montauk Highway is an east–west road extending for 95 miles (153 km) across the southern shore of Long Island in Suffolk County, New York, in the United States. It extends from the Nassau County line in Amityville, where it connects to Merrick Road, to Montauk Point State Park at the very eastern end of Long Island in Montauk. The highway is known by several designations along its routing, primarily New York State Route 27A (NY 27A) from the county line to Oakdale and NY 27 east of Southampton. The portion of Montauk Highway between Oakdale and Southampton is mostly county-maintained as County Route 80 and County Route 85 (CR 80 and CR 85, respectively).
