To allow for advanced Eighth Avenue Line Mezzanine work and the construction of a permanent underpass under the Lexington Avenue Line tunnel under Fulton Street to take place, the subway station entrance at 222 Broadway became permanently closed on October 29, 2011. In its place, a temporary entrance opened midblock between Fulton Street and John Street, inside the main building construction site. This was followed with a major realignment of the transfer passageway between the Eighth Avenue Line and Lexington Avenue Line trains. Related construction work saw the temporary closure of the entrances at Fulton Street, on the northwest (by St. Paul's Chapel) and southwest corners throughout much of 2011. Both were reopened by the first half of 2012. The entrance to Dey Street (195 Broadway), on the southbound platform, was permanently closed on May 1, 2012, for Dey Street Passageway related work and rehabilitation of the southbound platform. It was to be replaced by the Dey Street Headhouse, across Dey Street, when it opened in late September 2012.
