architectural graphics, entrances, and two escalators were installed. In a report published in 1991, the New York City Department of City Planning recommended closing the Graybar subway passage because of its low usage and its proximity to other connections. After a woman was raped in another subway passageway, the Graybar subway passage and 14 others were closed by emergency order of the New York City Transit Authority on March 29, 1991, with a public hearing being held afterward. From January 1, 1990, to its closure, there had been 365 felonies committed in the Graybar subway passage, making it the most dangerous of the 15 passageways ordered closed. The passageway had been located behind a token booth, making it hard to patrol; at the time of its closure, the hallway was described as being "deceptively long and treacherous". Work began on a five-year $82 million project to renovate the station in November 1995. The project, which was financed using state and Federal funds and designed by Gruzen Samton Architects, would focus on improving the appearance of the station, and would be constructed in phases. The renovation would restore the 1914 mosaic tiles on the walls of the Lexington Avenue Line platforms, cover existing columns with tile with new mosaics, create a v-shaped light installation on the vaulted ceiling of the Flushing Line platform, and install a contemporary mosaic frieze in multiple colors along the walls of the Shuttle platform. In addition, the stained concrete floors in the station complex would be replaced with pre-cast quartz terrazzo tiles, which would have the same color beige as the marble floors in Grand Central Terminal. Under a 1990s plan for the Second Avenue Subway, a spur to Grand Central Terminal was considered, which would have turned off Second Avenue at 44th Street as a way to divert riders from the , which run express on the Lexington Avenue Line. Service on this spur could not be as frequent as that on Lexington Avenue as there would not be enough capacity on Second Avenue, and as a result this plan was dropped. 21st century Renovations As part of the construction of One Vanderbilt at the corner of Vanderbilt Avenue and 42nd Street, developer SL Green Realty made several upgrades to the station. The improvements entailed multiple new entrances and exits, including two staircases to the southeast corner of Lexington Avenue and 42nd Street, as well
