South Tracks On The 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 ...

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] |
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] |
Henry Hornbostel
Henry Hornbostel (August 15, 1867 – December 13, 1961) was an American architect and educator. Hornbostel designed more than 225 buildings, bridges, and monuments in the United States. Twenty-two of his designs are listed on the National Register of Historic Places, including the Oakland City Hall in Oakland, California and the Soldiers and Sailors Memorial Hall and Museum and University Club in Pittsburgh, Pennsylvania. About The son of Edward Hornbostel, a stockbroker, and Johanna Cassebeer, Hornbostel was born and raised in Brooklyn, New York. He trained in architecture at Columbia University (BA 1891) and the École des Beaux-Arts in Paris (1893–97).

Gustav Lindenthal
Gustav Lindenthal (May 21, 1850 – July 31, 1935) was a civil engineer who designed the Queensboro and Hell Gate bridges in New York City, among other bridges. Lindenthal's work was greatly affected by his pursuit for perfection and his love of art. Having received little formal education and no degree in civil engineering, Lindenthal based his work on his prior experience and techniques used by other engineers of the time. Early life Lindenthal was born in Brünn, Austrian Empire, now Brno, Czech Republic in 1850. Lindenthal began to receive practical training in 1866 when he was employed as a mason and carpenter. At the age of 18, Lindenthal left his family to set out to make a life of his own in Vienna, Austria. Career When he arrived in Vienna he became an assistant in the engineering department for the Empress Elisabeth Railway of Austria. Two years later he joined the Union Construction Company, where he gained experience in building incline planes and railroads. ...

Municipal Art Commission
A municipality is usually a single administrative division having corporate status and powers of self-government or jurisdiction as granted by national and regional laws to which it is subordinate. The term ''municipality'' may also mean the governing body of a given municipality. A municipality is a general-purpose administrative subdivision, as opposed to a special-purpose district. The term is derived from French and Latin . The English word ''municipality'' derives from the Latin social contract (derived from a word meaning "duty holders"), referring to the Latin communities that supplied Rome with troops in exchange for their own incorporation into the Roman state (granting Roman citizenship to the inhabitants) while permitting the communities to retain their own local governments (a limited autonomy). A municipality can be any political jurisdiction, from a sovereign state such as the Principality of Monaco, to a small village such as West Hampton Dunes, New York. Th ...

Caisson (engineering)
In geotechnical engineering, a caisson ( or ; borrowed from French ''caisson'', from Italian ''cassone'', meaning ''large box'', an augmentative of ''cassa'') is a watertight retaining structure used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, or for the repair of ships. Caissons are constructed in such a way that the water can be pumped out, keeping the work environment dry. When piers are being built using an open caisson, and it is not practical to reach suitable soil, friction pilings may be driven to form a suitable sub-foundation. These piles are connected by a foundation pad upon which the column pier is erected. Caisson engineering has been used at least since the 18th century, and was notably used in the construction of the Brooklyn Bridge, which was completed in 1883. Types To install a caisson in place, it is brought down through soft mud until a suitable foundation material is encountered. While bedrock is pref ...

Wallabout Bay
Wallabout Bay is a small body of water in Upper New York Bay along the northwest shore of the New York City borough of Brooklyn, between the present Williamsburg and Manhattan Bridges. It is located opposite Corlear's Hook in Manhattan, across the East River to the west. Wallabout Bay is now the site of the Brooklyn Navy Yard. The nearby neighborhood of Wallabout, dating back to the 17th century, is adjacent to the bay. The neighborhood is a mixed use area with an array of old wood-frame buildings, public housing, brick townhouses, and warehouses; it contains the historic Lefferts-Laidlaw House, which was added to the National Register of Historic Places in 1985. The name of this curved bay on the western end of "Lang Eylandt" (Long Island) comes from the Dutch "Waal bocht", which means " Walloons' Bend", named for its first European settlers: the Walloons, from what is today Wallonia. History The Wallabout was first settled by Europeans when several families of French-spea ... [...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 ...

Deck (bridge)
A deck is the surface of a bridge. A structural element of its Superstructure#bridge, superstructure, it may be constructed of concrete, steel, grating, open grating, or wood. Sometimes the deck is covered by a track ballast, railroad bed and railroad track, track, asphalt concrete, or other form of pavement (material), pavement for ease of vehicle crossing. A concrete deck may be an integral part of the bridge structure (T-beam or double tee structure) or it may be supported with I-beams or steel girders. When a bridge deck is installed in a through truss, it is sometimes called a floor system. A suspended bridge deck will be suspended from the main structural elements on a suspension or arch bridge. On some bridges, such as a Tied-arch bridge, tied-arch or a Cable-stayed bridge, cable-stayed, the deck is a primary structural element, carrying tension or compression to support the span. A deck bridge is one in which the deck itself is the main structural element, itself carr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deflection (engineering)
In structural engineering, deflection is the degree to which a part of a structural element is displaced under a load (because it deforms). It may refer to an angle or a distance. The deflection distance of a member under a load can be calculated by integrating the function that mathematically describes the slope of the deflected shape of the member under that load. Standard formulas exist for the deflection of common beam configurations and load cases at discrete locations. Otherwise methods such as virtual work, direct integration, Castigliano's method, Macaulay's method or the direct stiffness method are used. The deflection of beam elements is usually calculated on the basis of the Euler–Bernoulli beam equation while that of a plate or shell element is calculated using plate or shell theory. An example of the use of deflection in this context is in building construction. Architects and engineers select materials for various applications. [Baidu] |
