By 1947, NY 12C and NY 69 were realigned to follow Oriskany Street through western Utica while NY 5A was extended eastward along Oriskany Street to a new terminus in downtown Utica, creating overlaps with both NY 12C and NY 69. The overlaps remained in place until January 1, 1970, when NY 12C was eliminated and NY 69 was truncated to end in Yorkville. The intersection between Commercial Drive and Oriskany Boulevard was converted into a trumpet interchange around the same time.
