Macombs Dam
Macombs Dam ( ) was a dam and bridge across the Harlem River between Manhattan and the Bronx in New York City, which existed from to . The bridge was later replaced with the toll-free Central Bridge, and since 1890, the current Macombs Dam Bridge has stood on the site. History Construction In 1813, Robert Macomb, son of the merchant Alexander Macomb, requested permission of the New York State Legislature to build a dam at the New York City Parks Department website which would hold water for a tide powered gristmill created by the new dam and another one Macomb owned near King’s Bridge on Spuyten Duyvil Creek. Fifty prominent citizens of the area, realizing that Macomb would most likely receive the permission he had asked for, petitioned the city's Common Council to allow a bridge to be built as part of the structure as well. This request was granted, and Macomb was allowed to collect tolls on the bridge, half of which would go to the Council to be used to ed ...

Croton Aqueduct
The Croton Aqueduct or Old Croton Aqueduct was a large and complex water distribution system constructed for New York City between 1837 and 1842. The great aqueducts, which were among the first in the United States, carried water by gravity from the Croton River in Westchester County to reservoirs in Manhattan. It was built because local water resources had become polluted and inadequate for the growing population of the city. Although the aqueduct was largely superseded by the New Croton Aqueduct, which was built in 1890, the Old Croton Aqueduct remained in service until 1955. Background The island of Manhattan, surrounded by brackish rivers, had a limited supply of freshwater available. It dwindled as the city grew rapidly after the American Revolutionary War, and freshwater sources became polluted by effluent. Before the aqueduct was constructed, residents of New York obtained water from cisterns, wells, natural springs, and other bodies of water. But rapid population growth ...

Washington Bridge
The Washington Bridge is a -long arch bridge over the Harlem River in New York City between the boroughs of Manhattan and the Bronx. The crossing, opened in 1888, connects 181st Street and Amsterdam Avenue in Washington Heights, Manhattan, with University Avenue in Morris Heights, Bronx. It carries six lanes of traffic, as well as sidewalks on both sides. Ramps at either end of the bridge connect to the Trans-Manhattan Expressway and the Cross-Bronx Expressway. The two-hinged arch bridge was designed by Charles C. Schneider and Wilhelm Hildenbrand, with modifications to the design made by the Union Bridge Company, William J. McAlpine, Theodore Cooper, and DeLemos & Cordes, with Edward H. Kendall as consulting architect. The bridge features steel-arch construction with two main arches and masonry approaches. The bridge is operated and maintained by the New York City Department of Transportation. It once carried U.S. Route 1, which now travels over the Alexander Ha ...

Brooklyn Bridge
The Brooklyn Bridge is a hybrid cable-stayed/suspension bridge in New York City, spanning the East River between the boroughs of Manhattan and Brooklyn. Opened on May 24, 1883, the Brooklyn Bridge was the first fixed crossing of the East River. It was also the longest suspension bridge in the world at the time of its opening, with a main span of and a deck above mean high water. The span was originally called the New York and Brooklyn Bridge or the East River Bridge but was officially renamed the Brooklyn Bridge in 1915. Proposals for a bridge connecting Manhattan and Brooklyn were first made in the early 19th century, which eventually led to the construction of the current span, designed by John A. Roebling. The project's chief engineer, his son Washington Roebling, contributed further design work, assisted by the latter's wife, Emily Warren Roebling. Construction started in 1870, with the Tammany Hall-controlled New York Bridge Company overseeing construction, alth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
