New York State Route 237 (NY 237) is a north–south state highway located in the western part of New York in the United States. The southern terminus of the route is at an intersection with NY 5 in Stafford. Its northern terminus is at an interchange with the Lake Ontario State Parkway immediately south of Lake Ontario in Kendall. NY 237 passes through mostly rural areas of Genesee and Orleans counties; however, it also passes through several small communities, including the village of Holley. In the 1930 renumbering of state highways in New York, NY 237 was assigned to the portion of its modern alignment south of what is now NY 104 in Murray while the segment of modern NY 237 between current NY 104 and NY 18 was designated as New York State Route 385. NY 237 was extended northward to Kendall , replacing NY 385. It was extended northward once more in the early 1970s to meet the Lake Ontario State Parkway. Route description NY 237 begins at an intersection with NY 5 east of Batavia in the Genesee County town of Stafford. It heads northward from the hamlet of Stafford as Morganville Road, traversing open fields on its way to the hamlet of Morganville to the north. Here, the route takes on a northeast alignment for a brief distance before resuming a northerly alignment as it exits the community. North of Morganville, NY 237 crosses open terrain and passes over the New York State Thruway (Interstate 90) ahead of an isolated junction with NY 33—which parallels the Thruway along this stretch—near the northern town line. The route continues north into the town of Byron and the hamlet of South Byron, a small community built up around the CSX Transportation-owned Rochester Subdivision. NY 237 quickly proceeds through South Byron, passing under the railroad line on its way toward the hamlet of Byron. In the center of Byron, NY 237 meets NY 262, which becomes county-maintained as the eastern segment of County Route 13 (CR 13) east of NY 237. Past NY 262, NY 237 proceeds through the residential northern outskirts of the hamlet to Pumpkin Hill, the last community that NY 237 enters prior to crossing into Orleans County. Outside of Pumpkin Hill, the route passes through sparsely developed areas of Byron and Clarendon, serving the small hamlet of Honest Hill in the southern portion of the latter.
