The FHWA eventually approved the withdrawal from the Interstate System of I-478 (Westway) from Manhattan, New York City on September 30, 1985. The action severed the short sections of I-495 through the Lincoln Tunnel in both New Jersey and New York from the rest of the Interstate System. Since they were no longer linked, the action also removed I-495 west from I-478 under the provisions of 23 U.S.C. 103 (f).
NJDOT and the New York State Department of Transportation (NYSDOT) followed with separate applications to AASHTO formally requesting the removal of the Lincoln Tunnel from the Interstate System. They were approved on June 10, 1986.
The freeway west from the Lincoln Tunnel was redesignated as New Jersey Route 495. The New York section of Interstate 495 remains east of the Queens Midtown Tunnel. It was eventually extended to cover the remaining distance of the Long Island Expressway to Riverhead in 1984.
