 Upon crossing the county line, Ridge Road becomes county-maintained as CR 103.The route heads along the top of the escarpment, passing by a smattering of homes, while NY 104—visible from Ridge Road for most of the latter's routing through the town of Ontario—serves a line of businesses at the escarpment's base.The two roads, which run parallel to one another between the village of Webster and Ontario Center, begin to separate at NY 350 in Ontario Center.
