New York State Route 59
state highway in Rockland County, New York, US
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.

Why this record matters
The subject matters to the places & architecture register because the source frames it as state highway in Rockland County, New York, US. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Jul 27, 2026. The linked authority identifier is Q2486125. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1911, 1932 and 1937.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
