Within the U.S. state of New York, Interstate 81 spans 183.52 miles (295.35 km) from the Pennsylvania state line to the south to the Canadian border in the north. The route enters New York near Kirkwood, southeast of Binghamton, and heads north through Binghamton, Syracuse, and Watertown before crossing into Canada in the Thousand Islands near Fishers Landing. Within the Thousand Islands, I-81 crosses two bridges, both part of the series of bridges known as the Thousand Islands Bridge.

[edit] Route description

[edit] 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.

Bolded cities are officially-designated control cities for signs

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.

[edit] 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.[2] By 1967, all of I-81 within the state was open to traffic except for the portion of modern I-81 between NY 221 in Marathon and NY 26 in Whitney Point.[3] The Marathon-Whitney Point segment was completed in 1969.[4]
