After the opening of the Clearview interchange, the Long Island Expressway was open between Manhattan and Roslyn and entirely designated as NY 24. The old surface alignment of NY 24 south of the expressway became NY 24A. The LIE was extended east from the Northern State Parkway split to NY 106/107 in Jericho by 1960, and was then opened to South Oyster Bay Road in Syosset in December 1960. By 1962, the NY 24 designation was removed from the LIE and reassigned to its former surface alignment to the south while the portion of the freeway east of the Clearview Expressway became NY 495 (and later, I-495).
