NY 47 followed the entire alignment of NY 204 to what is now I-390 and continued on Brooks Avenue into Rochester to Genesee Park Boulevard. Route 47 turned south onto the street, which circles around the southwestern quadrant of the city, and followed its length to Genesee Street, where it turned south for a short distance before resuming its eastward alignment on Elmwood Avenue. The route remained on Elmwood Avenue into Brighton, where it turned north onto South Winton Road at Twelve Corners. At Highland Avenue, NY 47 reentered Rochester and became North Winton Road at East Avenue (NY 96). The route remained on Winton through Rochester and Irondequoit before terminating at Empire Boulevard (then US 104, now NY 404) just west of Irondequoit Bay.
