It opened in 1918 as part of the Dual Contracts (Contract 3) IRT system.","why_significant":"The station is significant under Criterion A for transportation, community planning and development, and social history, and under Criterion C for engineering, architecture and art. It is a representative example of simpler Dual System station design, with original white tile walls, Arts and Crafts mosaic bands and faience plaques. It retains a high degree of integrity and helped development on the western side of Lower Manhattan.","narrative":"Chambers Street Station is a two-level, four-track subway station with double island platforms, running beneath West Broadway in Lower Manhattan. It opened in 1918 as part of Contract 3 of the Dual Contracts, the largest period of subway expansion in the city's history. Built by a variation of cut-and-cover construction, it has a steel frame, concrete foundation and brick side walls. Design architect Squire J. Vickers gave the platforms white ceramic tile walls, green, brown and gold mosaic friezes, and 62 faience plaques depicting the first building of Kings College, the original name of Columbia University. The mezzanine is open to the platforms below, an unusual feature. Water damage has stained some tile and mosaics, and modern fixtures have been added, but the station keeps most of its original character. It is considered a representative example of Dual System design and contributed to the growth of western Lower Manhattan by bringing thousands of workers downtown.","period_of_significance":"1918","architect_builder":"Vickers, Squire J.
