Route description

Pennsylvania to Syracuse

Interstate 81 enters New York at the Pennsylvania state line about 11 miles south east of Binghamton. I-81 merges with NY 17 for 5 miles. The current segment of NY 17 is set to become I-86. About 1 mile north of Binghamton at exit 5, I-81 meets the western terminus of I-88. US 11 has been paralleling I-81 from Virginia and US 11 will parallel I-81 in most of New York. At mile marker 73 and exit 15, I-81 meets with the longest road in the United States: US 20 in La Fayette. At the southern tip of Syracuse, at mile marker 81, and exit 16A, I-81 meets with one of its spurs: I-481. In downtown Syracuse, I-81 meets I-690 at an incomplete interchange.

yracuse to Canada

Just north of Syracuse, I-81 meets the New York State Thruway (Interstate 90) at exit 25A. In North Syracuse at mile marker 93, I-81 meets with I-481 and NY 481 at exit 29. From exit 36 to exit 48, I-81 begins to parallel Lake Ontario. I-81 ends at Thousand Islands Bridge (toll northbound only) at the U.S./ Canadian border 6 miles north of Fishers Landing.

Around I-81's northern terminus at the Canadian border, two toll bridge spans over the St. Lawrence River connect it to Highway 401 (via Highway 137) in Ontario. The main bridge span on the United States side is one of the few remaining 2-lane Interstate stretches left on the system. The border itself is marked by a 90-foot bridge across the International Rift between Wellesley Island, New York and Hill Island, Ontario.

History

The entirety of I-81 within New York was designated along with the remainder of modern I-81 in the 1957 plan for the Interstate Highway System.American Association of State Highway Officials. ".]
