New York State Route 89

New York State Route 89 (NY 89) is a north–south state highway in central New York in the United States. It extends for 62.35 miles (100.34 km) from an intersection with NY 13, NY 34, and NY 96 in the Tompkins County city of Ithaca to an interchange with NY 104 in the Wayne County town of town of Wolcott. The route spans a total of three counties, connecting the heart of the Finger Lakes Region to a point 6 miles (10 km) south of Lake Ontario. Along the way, NY 89 intersects two regionally important highways: the conjoined routes of U.S. Route 20 (US 20) and NY 5 in Seneca Falls and NY 31 in Savannah. NY 89 runs along the western edge of Cayuga Lake from Ithaca to Seneca Falls.

NY 89 was assigned as part of the 1930 renumbering of state highways in New York to a significantly different alignment than it follows today. At the time, the route began in Varick and passed through Seneca Falls and Clyde before ending near North Rose. It was extended south to Ithaca c. 1933 and rerouted north of Seneca Falls in the late 1950s to serve Savannah and Wolcott instead. The latter change supplanted part of NY 414, which was subsequently moved onto NY 89's original routing from Seneca Falls to North Rose. NY 89 originally extended into the village of Wolcott; however, it was cut back to its current northern terminus after the NY 104 super two was constructed in the early 1970s.
