After forking from NY 54, NY 415 proceeds northwest along West Morris Street, a two-lane commercial boulevard serving the western extents of the village of Bath. NY 415 soon begins to parallel the B&H main line once again, leaving the village for substantially less developed areas of the town of Bath. Roughly from the village, the route turns westward, passing under the Southern Tier Expressway to reach the Cohocton River and a junction with nearby CR 15 (Knight Settlement Road). Past CR 15, NY 415 heads northwest as a two-lane farm road to the riverside hamlet of Kanona, where NY 415 intersects with the southern terminus of NY 53 (Main Street). The route continues on, crossing the river and intersecting CR 14 (Campbell Creek Road) before leaving the residential community.
