The rest of the mezzanine was closed on an emergency basis in April 1991, after the NYCTA, on March 28, 1991, ordered the closing of the 15 most dangerous passageways in the subway system within a week following the rape of a woman behind a pile of debris in a passage connecting the 34th Street–Herald Square and 42nd Street–Bryant Park stations under Sixth Avenue on March 20, 1991. The locations were chosen based on crime volume, lighting, traffic and physical layout, and were closed under the declaration of a public safety emergency. The areas were blocked off with plywood and fencing until public hearings were held and official permission was obtained. By closing the entrances, the transit police could deploy many officers to other parts of the system. The crossover at the mezzanine was chosen because the station had 96 felonies since January 1, 1990. In January 1992, the MTA Board approved a request by the NYCTA to close 43 full-time or part-time station areas at 30 station complexes, including the crossover. With the closure of the crossover, during late nights, when the part-time booth to the Queens-bound platform was closed, passengers would use the existing high entrance and exit turnstiles. The NYCTA was also considering making this booth full-time.
