In Campbell, NY 415 runs through mostly wooded, rural areas, save for a handful of homes in hamlets along the route. In Curtis, located about from Coopers Plains, NY 415 connects to the eastern terminus of CR 4 (Curtis Hollow Road). The highway continues northward from Curtis, closely paralleling the Cohocton River for another to the hamlet of Campbell. NY 415 bypasses most of the community to the east; as a result, the route serves only a small number of homes on the outskirts of the community. As the highway heads through the area, it meets the east end of CR 333 (Main Street), which heads westward into Campbell's business district. The junction with CR 333 was the former eastern terminus of NY 333, a designation eliminated in 1997. NY 415 continues northwest from this point, intersecting with CR 17 (McNutt Run Road) before leaving the hamlet for less developed areas of the town.
