The project consists of design and construction of the structural box for the new South Ferry station on metro line 1 in lower Manhattan. The new terminal station will consist of two tracks and a 10-car-length centre island platform. The station will replace the existing substandard 5-car length station. The proposed approach tunnel and station will be constructed underneath three existing metro tunnels. Valued at over USD200 million, the project begins with modifications to be made at the existing metro tunnel under Greenwich Street, north of Battery Place so that the new tunnel can diverge to the west and proceed beneath a portion of Battery Park and then cross beneath the existing tunnel approach to the South Ferry loop tracks, and beneath the Line 4/5 metro tunnel to Brooklyn. The new station alignment will continue adjacent to State Street and terminate under Peter Minuit Plaza in front of the newly constructed Whitehall Ferry terminal. When completed in 2007, the new station will allow increased throughput and therefore increase the overall capacity of the entire 7th Avenue/Broadway Line.
