New York State Route 17 (NY 17) is a major east-west state highway that extends for 397 miles (638.91 km) through the Southern Tier and Downstate regions of New York in the United States. It begins at the Pennsylvania state line in Mina and follows the Southern Tier Expressway and Quickway east through Corning and Binghamton to Woodbury, where it turns south to follow the Orange Turnpike to the New Jersey state line near Suffern, where it connects to that state's Route 17. From the Pennsylvania border to the city of Elmira and from Binghamton to Windsor, NY 17 is concurrent with Interstate 86 (I-86). Eventually, the entire east–west portion of NY 17 from the Pennsylvania border to Woodbury will become I-86 as projects to upgrade the route to Interstate Highway standards are completed.
