Numbered highways in New York

Part of the series on Highways in New York Interstate Highways U.S. Routes State routes (former) Reference routes County routes Parkways

The New York State Department of Transportation (NYSDOT) is responsible for the establishment and classification of a state highway network which includes interstate highways, U.S. highways, and state routes. U.S. and Interstate highways are classified as state routes in New York; however, a letter ("U" or "I", respectively) is suffixed to the number of the route. As a result, there is apparent duplication between U.S. routes, Interstates and state routes.

Thruway

Main article: New York State Thruway

Highways maintained by the New York State Thruway Authority lack any signed numbers apart from Interstate Highway designations. While the vast majority of the Thruway system is part of the Interstate Highway System, some sections, such as the Berkshire Connector between Interstate 87 and Interstate 90, are unsigned reference routes. There are no standard NYSDOT reference markers on any of the highways; instead, the Thruway Authority posts their own mileposts, which (aside from the mainline) bear special Thruway codes. See the Thruway article for details.
