Hill State Forest. Climbing a steep hill northeast, the route leaves Little Valley for the town of Mansfield and intersects with the other terminus of CR 15. At the junction with Windsor Road and the summit of the hill, NY 242 bends eastward for a short stretch, entering a small residential section as the route leaves Mansfield and descends steeply toward the village of Ellicottville. In Ellicottville, NY 242 gains the moniker of West Washington Street, paralleling Sunset Hill Cemetery and crossing the Finger Lakes Trail before entering the village into downtown, where the route intersects with US 219 (Jefferson Street). US 219 and NY 242 become concurrent at the junction of Jefferson and Washington, running northeast through the village as a two-lane commercial street along the Great Valley Creek. At the junction with Mill Street, US 219 and NY 242 take East Washington Street northeast along Great Valley Creek, entering the town of Ellicottville. The two routes fork nearby as NY 242 winds northeast along the creek through Ellicottville, paralleling railroad tracks into the hamlet of Ashford Junction, where it intersects with the southern terminus of NY 240. The route continues northeast out of Ashford, crossing the railroad tracks a short distance from NY 240. Making a more east-northeast progression, NY 242 crosses into the town of Franklinville and the hamlet of Devereaux. After Devereaux, NY 242 turns northward and crosses through swampland in Franklinville. Crossing into the hamlet of Bakerstand, the route intersects with the western terminus of CR 17 (Bakerstand Road). After Bakerstand, the route crosses into the town of Machias, leaving the swamp for the hamlet of Bird. After Bird, NY 242 turns northeast near Very Road to an intersection with CR 62 (Maple Avenue). Paralleling the railroad tracks, the route crosses south of the hamlet of Machias, reaching an intersection with NY 16 (Main Street). This junction marks the eastern terminus of NY 242. History The portion of NY 242 between Windsor Road in Mansfield and Bryant Hill Road in Ellicottville follows the historic Chautauqua Road, one of the oldest roads in Western New York and one that was commissioned by the Holland Land Company in the 1810s. From Windsor Road westward to Little Valley, it follows a path that was originally a detour after the original path proved too treacherous to traverse, and from there westward it joined the Jamestown Road, another early pathway
