A pedestrian arcade between 56th and 55th Streets is included in CitySpire's base as part of its construction.[34] The arcade is one of nine passageways that form 6½ Avenue, a set of full-block passageways from 51st to 57th Street between Sixth and Seventh Avenues.[35][36] It was built as a "through-block connection" under the Special Midtown District, created in 1982.[35] The connection itself was not opened until 1997, several years after the building opened;[4] the delay was largely due to the building's foreclosure and other disputes in the early 1990s.[37] The arcade, designed by Brennan Beer Gorman, consists of marble and granite walls as well as a 25-foot (7.6 m) ceiling.[38][39] The passageway is decorated in an Art Deco-inspired style, with theater posters on the walls.[39][36] The space has recessed lights on the ceiling and lights on the walls, but there is no seating since the passageway was designed merely for pedestrian movement.[39]
