NY 47 was originally routed along surface streets through the city when it was assigned . It began at NY 31 in Gates and followed Howard Road and Brooks Avenue southeast into Rochester, where it continued eastward on Genesee Park Boulevard and Elmwood Avenue. NY 47 remained on the latter through Brighton to an area known as Twelve Corners. At this point, the route turned north onto Winton Road and followed that street through the eastern fringe of the city to Irondequoit, where NY 47 ended at a junction with U.S. Route 104 (US 104, now NY 404). The Outer Loop was constructed in stages, beginning with the portion of the Sea Breeze Expressway north of Ridge Road in the early 1950s. From that point on, construction progressed in a generally clockwise fashion around the city.
