The list of Interstate Highways in New York encompasses 29 currently in-use Interstate Highways—eight primary Interstates and 21 auxiliary Interstates—which exist entirely or partially in the U.S. State of New York. In New York, Interstate Highways are maintained by the New York State Department of Transportation (NYSDOT). Unlike in some other states, Interstates in New York are not referenced by NYSDOT with their number; 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. Interstate Highways travel for a combined total of 1,674 mi (2,694 km) in the state, which accounts for about 19 percent of vehicle travel in New York.1

At approximately 0.50 mi (0.80 km), I-78 is the shortest Primary Interstate, while I-90 is the longest, spanning 385.88 mi (621.01 km) within New York. I-878 located in Queens is the shortest auxiliary route currently in use in the Interstate Highway system. In New York City, small portions of Interstate 278 are maintained by local authorities rather than the state transportation agency,2 a rare occurrence. In addition, Interstate 87, Interstate 287, Interstate 95, Interstate 90, Interstate 84, and Interstate 190 are designated as part of the New York State Thruway, which is operated by the New York State Thruway Authority .
