Interstate 86 marker

Interstate 86 (I-86) is an Interstate Highway that extends for 207 miles (333 km) through northwestern Pennsylvania and southern New York in the United States. The highway currently exists in two segments: the longer of the two begins at an interchange with I-90 east of Erie, Pennsylvania, and ends at the Chemung-Tioga County line, while the second extends from I-81 east of Binghamton to NY 79 in Windsor. When projects to upgrade the existing NY 17 to Interstate Highway standards are completed, I-86 will extend from I-90 near Erie to the New York State Thruway (I-87) in Woodbury. The current and future alignment of I-86 is known as the Southern Tier Expressway west of I-81 in Binghamton and the Quickway east of I-81.

I-86 currently travels 6.99 miles (11.25 km) in Pennsylvania and 199.86 miles (321.64 km) in New York. Except for a section of about 1.5 miles (2.4 km) that dips into Pennsylvania near the New York village of Waverly and the Pennsylvania borough of South Waverly, the rest of I-86 will be in New York. The section of NY 17 through South Waverly is maintained by the New York State Department of Transportation (NYSDOT), however. The Southern Tier Expressway section of I-86 and NY 17 comprises Corridor T of the Appalachian Development Highway System. I-86 connects to U.S. Route 219 (US 219) in Salamanca, I-390 near Avoca and I-99 / US 15 just west of Corning.
