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 from the
Pennsylvania state line at
Ripley to the
Massachusetts state line at
Canaan. Although most of the route is part of the tolled
New York State Thruway, a non-tolled section (situated in the
Capital District and not part of the Thruway system) 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.
