Within Rochester, NY 3 remained on the current alignment of NY 31 to what is now the intersection of Lyell Avenue and Broad Street. Here, NY 3 broke from modern NY 31 and continued east on Lyell Avenue to State Street. NY 3 then followed State Street, Main Street, and East Avenue (modern NY 96) through downtown before turning north onto Culver Road in the eastern portion of the city. The route remained on Culver Road to Empire Boulevard, where it turned east toward Irondequoit. Once in Irondequoit, it followed what is now NY 404 around the southern extent of Irondequoit Bay to Webster. NY 3 was realigned by 1930 to stay on East Avenue to Winton Road near the eastern edge of the city. Here, the route turned north, following Winton Road through eastern Rochester to Irondequoit, where it rejoined its previous routing at Empire Boulevard.
