New York State Highway 17

New York State Highway 17 runs from Suffern, New York (where is connects to NJ 17) to Corning, New York (where it connects to Interstate 86). NY 17 is gradually being replaced by the Interstate 86 moniker as at-grade intersections are being replaced and the road comes up to interstate code. North and west of Harriman, New York, at its intersection with Interstate 87 and United States Highway 6, NY 17 is known as the 'Quickway,' connecting the New York City metropolitan area with the southern-tier and Pennsylvania. Interstate 86, which will eventually connect Interstate 90 in the Erie, Pennsylvania area to I-87/US-6 near Harriman, NY, will be named the "Southern-Tier Expressway".
