New York State Highway 17 runs from Suffern, New York (where it connects to NJ 17) to the Pennsylvania border in Western New York where it connects to Interstate 86. NY 17 is gradually being resigned as Interstate 86 as part of an upgrade to the route, replacing at-grade intersections and bringing the road up to Interstate standards. North and west of Harriman, New York, at its intersection with Interstate 87 and U.S. Highway 6, NY 17 is known as the 'Quickway,' connecting the New York City metropolitan area with the southern-tier and Pennsylvania. It is named the "Southern-Tier Expressway" to Interstate 81, where it becomes "The Quickway".
