New York State Route 414 (NY 414) is a north–south state highway in the Southern Tier and Finger Lakes regions of New York in the United States. It extends for 83.20 miles (133.90 km) from an intersection with NY 352 in the Steuben County city of Corning to a junction with NY 104 in the Wayne County town of Huron. NY 414 spans five counties and roughly parallels NY 14 between Watkins Glen and Huron. It intersects every major east–west arterial in western New York, including the Southern Tier Expressway, U.S. Route 20 (US 20) and NY 5, and the New York State Thruway (I-90). The route passes through mostly rural areas as it travels between the several villages and cities along its routing.

New York State Route 352 (NY 352) is a state highway in the Southern Tier of New York in the United States. It generally parallels the Southern Tier Expressway from the village of Riverside (exit 45) east through the city of Corning to the city of Elmira (exit 56). The portion of NY 352 west of the hamlet of Big Flats was once part of NY 17; the rest was originally New York State Route 17E. Construction of and improvements to the Southern Tier Expressway have resulted in extensions of NY 352, primarily along the former NY 17 right-of-way.
