As part of the reorganization of the Fulton Street station complex, and to mitigate passenger flow congestion during the construction phases of the Fulton Center project, some new entrances opened and some existing entrances closed. In January 2007, the MTA opened a new entrance on the southeast corner of Maiden Lane and Broadway. Like the John Street entrance, it served chiefly the northbound platform of the Lexington Avenue Line. That month, construction began on creating an analogous entrance on Cortlandt Street, just across the street from Broadway, for the southbound platform. These entrances allowed for the temporary closure of the John Street entrance (northbound platform) and the entrance by Dey Street (southbound platform) during the rehabilitation of the Lexington Avenue Line platforms and Dey Street Passageway-related work.
