By the late 1960s and early 1970s, the Outer Loop was complete from NY 383 to US 104 west of the city and from modern I-590 exit 1 to the lakeshore east of Rochester. NY 47 followed the loop from US 104 south to NY 383 and from Elmwood Avenue north to modern NY 590 exit 8; north of that point, the expressway was part of US 104 and NY 18. NY 47 was extended northward along the remainder of the Sea Breeze Expressway in 1970. On March 18, 1980, the NY 47 designation was removed and replaced with several others, primarily I-390, I-590, NY 390, and NY 590.
