New York State Route 240 (NY 240) is a 51.64-mile (83.11 km) state highway in western New York in the United States. The southern terminus of the route is at an intersection with NY 242 in the Ellicottville community of Ashford Junction in northern Cattaraugus County. Its northern terminus is at a junction with NY 324 and Interstate 290 (I-290) in Amherst in northern Erie County. The route passes through the villages of Springville and Orchard Park, where it meets NY 39 and U.S. Route 20A (US 20A), respectively. Much of NY 240 between Concord and Aurora follows the west branch of Cazenovia Creek. The northern part of NY 240 in Erie County, named Harlem Road, is a major north–south route through the suburbs east of the city of Buffalo.
From its southern terminus at NY 242 to the hamlet of Glenwood in the town of Colden, NY 240 is a state highway in name only as the roadway is maintained by the highway departments of Cattaraugus and Erie counties. Within Cattaraugus County, NY 242 is co-designated as County Route 32 (CR 32). CR 32 is the only route that has a marked concurrency with a state route in the county. At the county line, it becomes County Route 198 and, later, County Route 30 before becoming state-maintained in Glenwood. A section between CR 198 and CR 30 is also designated as part of CR 27.
NY 240 was first designated in the renumbering of state highways in New York in 1930 from NY 39 in Springville to NY 18 near downtown Buffalo. The portion between Springville and Ashford was a section of NY 62 and Harlem Road was unnumbered. The section south of CR 16 in West Valley was a portion of NY 242. NY 240 instead used Abbott Road and South Park Avenue to get to Buffalo, which got extended to NY 5 in the 1930s. NY 240 was realigned south to Ellicottville in the mid-1960s, after numerous bypasses and realignments had been done by the State of New York Department of Public Works. NY 240 was realigned onto Harlem Road c. 1962. The former alignment to Buffalo is now designated as NY 950M, a reference route.
