New York State Route 225

New York State Route 225 (NY 225) is a state highway in the Southern Tier of New York in the United States. It is a 15.54-mile (25.01 km) loop route off NY 352 that connects the town of Big Flats (near the city of Elmira) and the city of Corning to the hamlet of Caton. The route begins in Big Flats and follows a generally east–west alignment across rural areas to Caton, where it turns to run in a north–south direction toward Corning. Development along the highway increases once it enters the Corning suburb of South Corning, and the rest of the route serves residential neighborhoods in South Corning and Corning. NY 225 is two lanes wide for its entire length; however, part of the highway in South Corning also has a center turn lane.

The Caton–Corning segment of the route was acquired by the state of New York in 1911 and designated as part of NY 44 (now NY 414) as part of the 1930 renumbering of state highways in New York. It received its current designation in 1949 when NY 414 was truncated to begin in Corning. The highway leading east from Caton to Big Flats was county-maintained from the 1930s through the 1970s, even though it had been part of NY 13 from the 1930 renumbering to the 1940s. The state of New York assumed maintenance of the highway by 1986, and the new state highway became an extension of NY 225.
