By 1964, construction was underway on a new expressway leading south from I-490 at the Can of Worms to Elmwood Avenue east of Twelve Corners. The highway was completed , at which time NY 47 was realigned to follow the Sea Breeze Expressway and the new expressway south through the Can of Worms to its end at a partial interchange with Elmwood Avenue (now I-590 exit 3). It continued west on Elmwood Avenue to Twelve Corners, where it reconnected to its old alignment at Winton Road.
