The MAC voted to use wire cables in the bridge in September 1904. Lindenthal's plan was also rejected, over a dispute which revolved around whether his plan using eyebars was better than the more established practice of using wire cables. Additionally, the towers would have contained Modern French detail, while the anchorages would have been used for functions such as meeting halls. The same span dimensions from Buck's plan were used because work on the masonry pier foundations had already begun.
The proposal also called for each of the suspension towers to be made of four columns, to be braced transversely and hinged to the bottom of the abutments longitudinally. Another set of plans was unveiled that month by New York City Bridge Commissioner Gustav Lindenthal, in conjunction with Henry Hornbostel. The Municipal Art Commission raised objections to one of the bridge's plans in June 1904, which delayed the start of construction for the span. A $10 million grant for the bridge's construction was granted in May 1904 with the expectation that work on the bridge would start later that year. By 1903, three workers had died while working on the Brooklyn-side tower's caisson. Elevated and trolley routes would use the Manhattan Bridge, and there would be large balconies and enormous spaces within the towers' anchorages. A plan for the suspension bridge was announced in 1903. Construction on the foundations for the suspension towers had commenced by at least 1901. This design would have consisted of a main span of 1,470 feet (450 m) and approaches of 725 feet (221 m) each. : 548 These plans called for a suspension bridge with carbon steel wire cables and a suspended stiffening truss, supported by a pair of towers with eight braced legs. The earliest plans for what became the Manhattan Bridge were designed by R. Planning and construction Planning and initial work When there was only one, it was well enough to call it the Brooklyn Bridge, or the East River Bridge". In 1905, the Times renewed its campaign, stating, "All bridges across the East River are Manhattan bridges. When the name was confirmed in 1904, The New York Times criticized it as "meaningless", lobbied for one after Brooklyn's Wallabout Bay, and railed that the span "would have geographical and historical significance if it were known as the Wallabout Bridge". 3", but was given the name Manhattan Bridge in 1902. In the earliest plans it was to have been called "Bridge No. The bridge was the last of the three suspension spans built across the lower East River, following the Brooklyn and Williamsburg Bridges. Considered the forerunner of modern suspension bridges, it served as the model for many of the record-breaking spans built in the first half of the twentieth century. An innovative design, it was the first suspension bridge to employ Josef Melan's deflection theory for deck stiffening, resulting in the first use of a lightly-webbed weight-saving Warren truss for its construction. The bridge was designed by Leon Moisseiff, built by The Phoenix Bridge Company, and opened to traffic on December 31, 1909. It is one of four toll-free vehicular bridges connecting Manhattan Island to Long Island the nearby Brooklyn Bridge is just slightly further west, while the Queensboro and Williamsburg bridges are to the north. The main span is 1,480 ft (451 m) long, with the suspension cables being 3,224 ft (983 m) long. The Manhattan Bridge is a suspension bridge that crosses the East River in New York City, connecting Lower Manhattan at Canal Street with Downtown Brooklyn at the Flatbush Avenue Extension.
