The nominated length is 6375 feet.","why_significant":"The nomination argues the bridge is a significant early twentieth-century engineering work, with innovative shallow Warren stiffening trusses and flexible steel towers. Its Beaux-Arts entrance designed by Carrere & Hastings reflects the City Beautiful movement. It is also seen as a transitional structure in the emergence of modern design principles.","narrative":"Spanning the East River between the Lower East Side of Manhattan and downtown Brooklyn, this steel suspension bridge runs 6375 feet including its Manhattan approach. Two flexible steel towers carry the deck on four spun steel cables, with a clear span of 1470 feet. It has two vehicular levels and a subway line. Construction ran from 1901 to 1909, and the bridge opened on December 31, 1909. Engineer O.F. Nichols designed it with shallow Warren stiffening trusses and flexible towers, then considered innovative. Carrere & Hastings added a Beaux-Arts entrance on the Manhattan side, an elliptical colonnade modeled on Bernini's St. Peter's Colonnade and a triumphal arch inspired by the Porte St. Denis in Paris. Critics questioned pairing classical ornament with a modern steel structure, yet the New York Times praised the design in 1913. The bridge is valued as a transitional work in modern design and as a prominent East River crossing.","period_of_significance":"1900-","architect_builder":"Gustav Lindenthal, O.F.
