Plans for a vehicular bridge across the Hudson River were being considered as early as 1906, during the planning for the Holland Tunnel. Three possible locations for a Hudson River bridge were considered in the vicinity of 57th, 110th, and 179th Streets in Manhattan. These three locations were considered to be the only suitable locations for suspension bridges; other sites were rejected on the grounds of aesthetics, geography, or traffic flows. In 1920, English architect Alfred C. Bossom proposed a double-decker bridge with room for vehicular and railroad traffic near 57th Street in Midtown Manhattan. The same year, Othmar Ammann and Gustav Lindenthal proposed a vehicular and railroad bridge to 57th Street in Manhattan, topped by an office building that would have been the world's tallest. Lindenthal's plan failed because it did not receive permits from the United States Army Corps of Engineers or approval from the city, and because Midtown Manhattan real estate developers and planners opposed the plan. Ammann unsuccessfully attempted to convince Lindenthal to build his bridge elsewhere, without a tower atop the bridge's terminus. In January 1924, the New York State Chamber of Commerce voted against the 57th Street location in favor of another location upstream. Despite this, Lindenthal proposed that the Hudson River bridge be built there, and carry 16 railroad tracks and 12 lanes of automotive traffic.
