City Island Bridge
The City Island Bridge is a bridge in the New York City borough of the Bronx, connecting City Island with Rodman's Neck on the mainland. The original bridge, which carried vehicles from 1901 to 2015, was replaced by the current bridge (also called the City Island Causeway), which opened in 2017. A temporary bridge was used for the demolition and construction period between the original and new bridges. Old bridge Since the American Revolutionary War, there have been plans to link City Island with the mainland via means of a bridge. Before the original bridge named "City Island Bridge" was opened, there was another, unnamed bridge connecting City Island with the rest of the Bronx. The opening date of this first bridge is unclear; some sources attest that it opened in 1873, while one letter states that it opened in 1857—a disputed date since the letter's writer may have been referring to a past date. This first bridge, which was definitely under planning in the 1860s, was listed i ...

Eastchester Bay
Eastchester Bay is a sound between City Island and the mainland Bronx in New York City, New York. Technically, it is not a bay, since it is open to larger bodies of water at both ends. The northern end connects via a narrow channel to Pelham Bay (which is also really a sound, since it, in turn, opens onto Long Island Sound). The Hutchinson River empties into Eastchester Bay near the northern end. The lower portion of the bay opens onto the East River, Little Neck Bay, and Long Island Sound. Eastchester Bay is designated an Essential Fish Habitat by the National Marine Fisheries Service. Many yacht clubs and marinas line the bay on both sides, leading to a high level of recreational boating traffic. Traffic is particularly dense on weekends and Wednesday evenings in the summer, when the various clubs run sailboat races. There is also a high volume of commercial traffic. The bay opens onto the main shipping channel into New York from Long Island Sound, which is used by larg ...

Toll Bridge
A toll bridge is a bridge where a monetary charge (or ''toll'') is required to pass over. Generally the private or public owner, builder and maintainer of the bridge uses the toll to recoup their investment, in much the same way as a toll road. History The practice of collecting tolls on bridges harks back to the days of ferry crossings where people paid a fee to be ferried across stretches of water. As boats became impractical to carry large loads, ferry operators looked for new sources of revenue. Having built a bridge, they hoped to recoup their investment by charging tolls for people, animals, vehicles, and goods to cross it. The original London Bridge across the river Thames opened as a toll bridge, but an accumulation of funds by the charitable trust that operated the bridge (Bridge House Estates) saw that the charges were dropped. Using interest on its capital assets, the trust now owns and runs all seven central London bridges at no cost to taxpayers or users. In t ...

Daily News (New York)
The New York ''Daily News'', officially titled the ''Daily News'', is an American newspaper based in Jersey City, NJ. It was founded in 1919 by Joseph Medill Patterson as the ''Illustrated Daily News''. It was the first U.S. daily printed in tabloid format. It reached its peak circulation in 1947, at 2.4 million copies a day. As of 2019 it was the eleventh-highest circulated newspaper in the United States. Today's ''Daily News'' is not connected to the earlier '' New York Daily News'', which shut down in 1906. The ''Daily News'' is owned by parent company Tribune Publishing. This company was acquired by Alden Global Capital, which operates its media properties through Digital First Media, in May 2021. After the Alden acquisition, alone among the newspapers acquired from Tribune Publishing, the ''Daily News'' property was spun off into a separate subsidiary called Daily News Enterprises. History ''Illustrated Daily News'' The ''Illustrated Daily News'' was founded by Patters ...

City Island Bridge - From Sidewalk, 2011
A city is a human settlement of notable size.Goodall, B. (1987) ''The Penguin Dictionary of Human Geography''. London: Penguin.Kuper, A. and Kuper, J., eds (1996) ''The Social Science Encyclopedia''. 2nd edition. London: Routledge. It can be defined as a permanent and densely settled place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, production of goods, and communication. Their density facilitates interaction between people, government organisations and businesses, sometimes benefiting different parties in the process, such as improving efficiency of goods and service distribution. Historically, city-dwellers have been a small proportion of humanity overall, but following two centuries of unprecedented and rapid urbanization, more than half of the world population now lives in cities, which has had profound consequences for g ...

Cable-stayed Bridge
A cable-stayed bridge has one or more ''towers'' (or ''pylons''), from which cables support the bridge deck. A distinctive feature are the cables or stays, which run directly from the tower to the deck, normally forming a fan-like pattern or a series of parallel lines. This is in contrast to the modern suspension bridge, where the cables supporting the deck are suspended vertically from the main cable, anchored at both ends of the bridge and running between the towers. The cable-stayed bridge is optimal for spans longer than cantilever bridges and shorter than suspension bridges. This is the range within which cantilever bridges would rapidly grow heavier, and suspension bridge cabling would be more costly. Cable-stayed bridges were being designed and constructed by the late 16th century, and the form found wide use in the late 19th century. Early examples, including the Brooklyn Bridge, often combined features from both the cable-stayed and suspension designs. Cable-stayed ...

Arch Bridge
An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side. A viaduct (a long bridge) may be made from a series of arches, although other more economical structures are typically used today. History Possibly the oldest existing arch bridge is the Mycenaean Arkadiko Bridge in Greece from about 1300 BC. The stone corbel arch bridge is still used by the local populace. The well-preserved Hellenistic Eleutherna Bridge has a triangular corbel arch. The 4th century BC Rhodes Footbridge rests on an early voussoir arch. Although true arches were already known by the Etruscans and ancient Greeks, the Romans were – as with the vault and the dome – the first to fully realize the potential of arches for bridge construction. A list of Roman bridges compiled by the engineer Colin O'Connor featur ...

Swing Bridge
A swing bridge (or swing span bridge) is a movable bridge that has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the swing span (turning span) can then pivot horizontally as shown in the animated illustration to the right. Small swing bridges as found over canals may be pivoted only at one end, opening as would a gate, but require substantial underground structure to support the pivot. In its closed position, a swing bridge carrying a road or railway over a river or canal, for example, allows traffic to cross. When a water vessel needs to pass the bridge, road traffic is stopped (usually by traffic signals and barriers), and then motors rotate the bridge horizontally about its pivot point. The typical swing bridge will rotate approximately 90 degrees, or one-quarter turn; however, a bridge which intersects the navigation channel at an oblique angle may be built to rotate only 45 degrees, or ...

Fixed Span
Span is the distance between two intermediate supports for a structure, e.g. a beam or a bridge. A span can be closed by a solid beam or by a rope. The first kind is used for bridges, the second one for power lines, overhead telecommunication lines, some type of antennas or for aerial tramways. The span is a significant factor in finding the strength and size of a beam as it determines the maximum bending moment and deflection. The maximum bending moment M_ and deflection \delta_in the pictured beam is found using: :M_ = \frac :\delta_ = \frac = \frac where :q = Uniformly distributed load :L = Length of the beam between two supports (span) :E = Modulus of elasticity :I = Area moment of inertia Note that the maximum bending moment and deflection occur midway between the two supports. From this it follows that if the span is doubled, the maximum moment (and with it the stress) will quadruple, and deflection will increase by a factor of sixteen. For long-distance rope sp ...

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ...
