New York State Route 417 (NY 417) is an east–west state highway located in the Southern Tier of New York in the United States. It begins at exit 20 of the Southern Tier Expressway in the city of Salamanca and ends at a junction with NY 415 in Painted Post, west of the city of Corning. At 105.25 miles (169.38 km) in length, NY 417 is the longest of the state highways that were formerly part of NY 17 before the construction of the Southern Tier Expressway. It also diverges the most from the current NY 17, coming within 100 feet (30 m) of the Pennsylvania state line at one intersection.

New York State Route 17 (NY 17) is a major 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 east through Corning to Binghamton and the Quickway from Binghamton east to Woodbury, where it turns south to follow the Orange Turnpike to the New Jersey state line near Suffern, where it connects to New Jersey Route 17. From the Pennsylvania border to the village of Waverly 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.
