New York State Route 59 (NY 59) is an east–west state highway in southern Rockland County, New York, in the United States. The route extends for 14.08 miles (22.66 km) from NY 17 in Hillburn to U.S. Route 9W (US 9W) in Nyack. In Suffern, it has a concurrency with US 202 for 0.05 miles (0.08 km). NY 59 runs parallel to the New York State Thruway its entire route. The routing of NY 59 became a state highway in 1911 and was signed as NY 59 in the late 1920s.
When NY 59 was first assigned, it began at NY 17 in Suffern. A western bypass of Suffern was designated as New York State Route 339 c. 1932; however, it became part of a realigned NY 17 in the mid-1930s. NY 339 was reassigned to NY 17's former routing between Hillburn and Suffern, but it was replaced again c. 1937 by an extended NY 59. In the 1960s, proposals surfaced for the Spring Valley Bypass, a highway that would utilize the NY 59 corridor between NY 306 in Monsey and NY 45 in Spring Valley. The proposed highway was never built.
