Interstate 90 (I-90) is a part of the Interstate Highway System that runs from Seattle, Washington, to Boston, Massachusetts. In the U.S. state of New York, I-90 extends 385.88 miles (621.01 km) from the Pennsylvania state line at Ripley to the Massachusetts state line at Canaan, and is the second-longest highway in the state after NY 17. Although most of the route is part of the tolled New York State Thruway, two non-tolled sections exist along I-90 (the first, situated outside of Buffalo, is included in the Thruway system; the second, situated in the Capital District, is not part of the Thruway system and links Albany and its eastern suburbs). Within New York, I-90 has a complete set of auxiliary Interstates, which means that there are interstates numbered I-190 through I-990 in the state, with no gaps in between. For most of its length in New York, I-90 runs parallel to the former Erie Canal route, New York State Route 5 (NY 5), U.S. Route 20 (US 20) and the CSX railroad mainline that traverses the state.
