The $527-million new South Ferry subway station at Manhattan’s southern tip opened on March 16, with platforms now long enough to accommodate 10-car trains rather than five. The 4.5-year-long project included a $261-million design-build contract, held by a joint venture of Schiavone Construction Co., Secaucus, N.J., and Granite Halmar Construction Co. Inc., Tarrytown, N.Y., for the reinforced-concrete structural box, which accommodates a 1,200-ft-long approach tunnel and the 500-ft-long new station.
