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, although nume ...

Long Island
Long Island is a densely populated island in the southeastern region of the U.S. state of New York (state), New York, part of the New York metropolitan area. With over 8 million people, Long Island is the most populous island in the United States and the List of islands by population, 18th-most populous in the world. The island begins at New York Harbor approximately east of Manhattan Island and extends eastward about into the Atlantic Ocean and 23 miles wide at its most distant points. The island comprises four List of counties in New York, counties: Kings and Queens counties (the New York City Borough (New York City), boroughs of Brooklyn and Queens, respectively) and Nassau County, New York, Nassau County share the western third of the island, while Suffolk County, New York, Suffolk County occupies the eastern two thirds of the island. More than half of New York City's residents (58.4%) lived on Long Island as of 2020, in Brooklyn and in Queens. Culturally, many people in t ...

Roadway
A carriageway (British English) or roadway (North American English) consists of a width of road on which a vehicle is not restricted by any physical barriers or separation to move laterally. A carriageway generally consists of a number of traffic lanes together with any associated shoulder, but may be a sole lane in width (for example, a highway offramp). Description A single carriageway road (North American English: undivided highway) has one carriageway with 1, 2 or more lanes together with any associated footways (North American English: sidewalk) and road verges (North American English: tree belt). A dual carriageway road (North American English: divided highway) has two roadways separated by a central reservation (North American English: median). A local-express lane system (also called collector-express or collector-distributor) has more than two roadways, typically two sets of 'local lanes' or 'collector lanes' and also two sets of 'express lanes'. "Cars only" lane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Longest Suspension Bridge Spans
The world's longest suspension bridges are listed according to the length of their main span (i.e. the length of suspended roadway between the bridge's towers). The length of main span is the most common method of comparing the sizes of suspension bridges, often correlating with the height of the towers and the engineering complexity involved in designing and constructing the bridge. If one bridge has a longer span than another it does not necessarily mean that the bridge is longer from shore to shore (or from abutment to abutment). Suspension bridges have the longest spans of any type of bridge. Cable-stayed bridges, the next longest design, are practical for spans up to just over 1 kilometre. Therefore, , the 31 longest bridges on this list are the 31 longest spans of all types of vehicular bridges (other than floating pontoon bridges). Currently, the 1915 Çanakkale Bridge in Turkey holds the record since opening to traffic in March 2022, with a span of . Since 1998, the A ...

Clifton Suspension Bridge
The Clifton Suspension Bridge is a suspension bridge spanning the Avon Gorge and the River Avon, linking Clifton in Bristol to Leigh Woods in North Somerset. Since opening in 1864, it has been a toll bridge, the income from which provides funds for its maintenance. The bridge is built to a design by William Henry Barlow and John Hawkshaw, based on an earlier design by Isambard Kingdom Brunel. It is a Grade I listed building and forms part of the B3129 road. The idea of building a bridge across the Avon Gorge originated in 1753. Original plans were for a stone bridge and later iterations were for a wrought iron structure. In 1831, an attempt to build Brunel's design was halted by the Bristol riots, and the revised version of his designs was built after his death and completed in 1864. Although similar in size, the bridge towers are not identical in design, the Clifton tower having side cut-outs, the Leigh tower more pointed arches atop a red sandstone-clad abutment. Roller-mo ...

New York City Landmarks Preservation Commission
The New York City Landmarks Preservation Commission (LPC) is the New York City agency charged with administering the city's Landmarks Preservation Law. The LPC is responsible for protecting New York City's architecturally, historically, and culturally significant buildings and sites by granting them landmark or historic district status, and regulating them after designation. It is the largest municipal preservation agency in the nation. , the LPC has designated more than 37,000 landmark properties in all five boroughs. Most of these are concentrated in historic districts, although there are over a thousand individual landmarks, as well as numerous interior and scenic landmarks. Mayor Robert F. Wagner Jr. first organized a preservation committee in 1961, and the following year, created the LPC. The LPC's power was greatly strengthened after the Landmarks Law was passed in April 1965, one and a half years after the destruction of Pennsylvania Station. The LPC has been involved ...

National Historic Landmark
A National Historic Landmark (NHL) is a building, district, object, site, or structure that is officially recognized by the United States government for its outstanding historical significance. Only some 2,500 (~3%) of over 90,000 places listed on the country's National Register of Historic Places are recognized as National Historic Landmarks. A National Historic Landmark District may include contributing properties that are buildings, structures, sites or objects, and it may include non-contributing properties. Contributing properties may or may not also be separately listed. Creation of the program Prior to 1935, efforts to preserve cultural heritage of national importance were made by piecemeal efforts of the United States Congress. In 1935, Congress passed the Historic Sites Act, which authorized the Interior Secretary authority to formally record and organize historic properties, and to designate properties as having "national historical significance", and gave the Nation ...

Queensboro Bridge
The Queensboro Bridge, officially named the Ed Koch Queensboro Bridge, is a cantilever bridge over the East River in New York City. Completed in 1909, it connects the neighborhood of Long Island City in the borough of Queens with the Upper East Side in Manhattan, passing over Roosevelt Island. The bridge is also known as the 59th Street Bridge because its Manhattan end is located between 59th and 60th streets. The Queensboro Bridge carries New York State Route 25 (NY 25), which terminates at the bridge's western end in Manhattan, and also once carried NY 24 and NY 25A. The western leg of the Queensboro Bridge is flanked on its northern side by the freestanding Roosevelt Island Tramway. The bridge was, for a long time, simply called the Queensboro Bridge, but in March 2011, the bridge was officially renamed in honor of former New York City mayor Ed Koch. The Queensboro Bridge is the northernmost of four toll-free vehicular bridges connecting Manhattan Island to Long Island, ...

Williamsburg Bridge
The Williamsburg Bridge is a suspension bridge in New York City across the East River connecting the Lower East Side of Manhattan at Delancey Street with the Williamsburg neighborhood of Brooklyn at Broadway near the Brooklyn-Queens Expressway (Interstate 278). Completed in 1903, it was the longest suspension bridge span in the world until 1924. The bridge is one of four toll-free vehicular bridges connecting Manhattan Island and Long Island. The others are the Queensboro Bridge to the north, and the Manhattan and Brooklyn Bridges to the south. The Williamsburg Bridge once carried New York State Route 27A and was planned to carry Interstate 78, though the planned I-78 designation was aborted by the cancellation of the Lower Manhattan Expressway and Bushwick Expressway. History Construction Construction on what was then known as the "East River Bridge", the second to span it, began in 1896 after approval by the Governor of New York on May 27, 1895. The new bridge was to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manhattan Bridge
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. The main span is long, with the suspension cables being long. The bridge's total length is . It is one of four toll-free vehicular bridges connecting Manhattan Island to Long Island; the nearby Brooklyn Bridge is just slightly further downtown, while the Queensboro and Williamsburg bridges are to the north. The bridge was designed by Leon Moisseiff, built by The Phoenix Bridge Company, and opened to traffic on December 31, 1909. 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. 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 t ...

Tammany Hall
Tammany Hall, also known as the Society of St. Tammany, the Sons of St. Tammany, or the Columbian Order, was a New York City political organization founded in 1786 and incorporated on May 12, 1789 as the Tammany Society. It became the main local political machine of the Democratic Party, and played a major role in controlling New York City and New York State politics and helping immigrants, most notably the Irish, rise in American politics from the 1790s to the 1960s. It typically controlled Democratic Party nominations and political patronage in Manhattan after the mayoral victory of Fernando Wood in 1854, and used its patronage resources to build a loyal, well-rewarded core of district and precinct leaders; after 1850 the vast majority were Irish Catholics due to mass immigration from Ireland during and after the Irish Famine. The Tammany Society emerged as the center of Democratic-Republican Party politics in the city in the early 19th century. After 1854, the Society expan ...

Emily Warren Roebling
Emily Warren Roebling (September 23, 1843 – February 28, 1903) was an engineer known for her contributions over a period of more than 10 years to the completion of the Brooklyn Bridge after her husband Washington Roebling developed caisson disease (a.k.a. decompression disease) and became bedridden. She served as a liaison and supervisor of construction through communicating between her husband and on-site personnel. Her husband was the chief engineer during construction of the Brooklyn Bridge, which had been designed by his late father, John A. Roebling. Early life Emily was born on September 23, 1843, to Sylvanus and Phebe Warren at Cold Spring, New York. She was the second-youngest of twelve children. Emily's interest in pursuing education was supported by her older brother Major General Gouverneur K. Warren. The two siblings always had a close relationship.Weingardt, Richard: ''Engineering Legends: Great American Civil Engineers'', page 56. ASCE Publications, 2005. She ...
