On March 18, 1980, the NY 47 designation was eliminated and split into four other routes. From NY 104 in Greece to I-490, NY 47 became NY 390. The section from I-490 south to NY 383 was designated as part of I-390; however, it would not connect to the existing portion of I-390 south of Rochester until 1981, when the interchange between I-390 and I-590 was completed. The segment of NY 47 from Elmwood Avenue north to the Can of Worms became part of I-590, which continued southwest along the freeway to Winton Road. From the Can of Worms to Lake Ontario, NY 47 was redesignated NY 590.
