Construction began January 3, 1870. Events 1431 - Joan of Arc is handed over to the Bishop Pierre Cauchon. Year 1870 ( MDCCCLXX) was a Common year starting on Saturday (link will display the full calendar of the Gregorian calendar (or a Common The Brooklyn Bridge was completed thirteen years later and was opened for use on May 24, 1883. Events 1218 - The Fifth Crusade leaves Acre for Egypt. 1276 - Magnus Ladulås is crowned Year 1883 ( MDCCCLXXXIII) was a Common year starting on Monday (link will display the full calendar of the Gregorian calendar (or a Common On that first day, a total of 1,800 vehicles and 150,300 people crossed what was then the only land passage between Manhattan and Brooklyn. The bridge's main span over the East River is 1,595 feet 6 inches (486. 3 m). The bridge cost $15. 5 million to build and approximately 27 people died during its construction. [6]

One week after the opening, on May 30, a rumor that the Bridge was going to collapse caused a stampede which crushed and killed twelve people. Events 1416 - The Council of Constance, called by the Emperor Sigismund a supporter of Antipope John XXIII burns Jerome of Prague following [7].

At the time it opened, it was the longest suspension bridge in the world — 50% longer than any previously built — and it has become a treasured landmark. Additionally, for several years the towers were the tallest structures in the Western Hemisphere. Since the 1980s, it has been floodlit at night to highlight its architectural features. The towers are built of limestone, granite, and Rosendale cement. Rosendale cement refers to a type of natural Cement produced in and around Rosendale New York. Their architectural style is Gothic, with characteristic pointed arches above the passageways through the stone towers. See also Gothic art Gothic architecture is a style of Architecture which flourished during the high and late medieval period.

The bridge was designed by German-born John Augustus Roebling in Trenton, New Jersey. Germany, officially the Federal Republic of Germany ( ˈbʊndəsʁepuˌbliːk ˈdɔʏtʃlant is a Country in Central Europe. John Augustus Roebling (born Johann August Röbling, June 12, 1806 in Mühlhausen - July 22, 1869) was a German-born Trenton is the Capital of the US state of New Jersey and the County seat of Mercer County. Roebling had earlier designed and constructed other suspension bridges, such as Roebling's Delaware Aqueduct in Lackawaxen, Pennsylvania, the John A. Roebling Suspension Bridge in Cincinnati, Ohio and the Waco Suspension Bridge in Waco, Texas, that served as the engineering prototypes for the final design. Roebling's Delaware Aqueduct is the oldest existing wire Suspension bridge in the United States; it runs 535 feet (175 m from Minisink Ford New York Lackawaxen Township is the largest and northernmost township in Pike County, Pennsylvania. The John A Roebling Suspension Bridge spans the Ohio River between Cincinnati Ohio and Covington Kentucky. The Waco Suspension Bridge crosses the Brazos River in Waco Texas. Waco (ˈweɪkoʊ is a city in and the County seat of McLennan County, Texas.

During surveying for the East River Bridge project, Roebling's foot was badly injured by a ferry, pinning it against a pylon; within a few weeks, he died of tetanus. Tetanus is a medical condition that is characterized by a prolonged contraction of Skeletal muscle fibres His son, Washington, succeeded him, but in 1872 was stricken with caisson disease (decompression sickness, commonly known as "the bends"), due to working in compressed air in caissons. Washington Augustus Roebling ( May 26, 1837 &ndash July 21, 1926) was an American Civil engineer best known for his work In Geotechnical engineering, a caisson is a retaining watertight structure used for example to work on the foundations of a Bridge pier, Decompression sickness (DCS, the diver’s disease, the bends, caisson disease is the name given to a variety of symptoms suffered by a person The occurrence of the disease in the caisson workers caused him to halt construction of the Manhattan side of the tower 30 feet (10 m) short of bedrock when soil tests underneath the caisson found bedrock to be even deeper than expected. Today, the Manhattan tower rests only on sand. [8] Washington's wife, Emily Warren Roebling, became his aide, learning engineering and communicating his wishes to the on-site assistants. Emily Warren Roebling (1843 &ndash 1903 was born to Phoebe Lickley and Sylvanus Warren in the village of Cold Spring New York, on the eastern shore of the Hudson River When the bridge opened, she was the first person to cross it. Washington Roebling rarely visited the site again.

At the time the bridge was built, the aerodynamics of bridge building had not been worked out. Bridges were not tested in wind tunnels until the 1950s — well after the collapse of the Tacoma Narrows Bridge in 1940. A wind tunnel is a research tool developed to assist with studying the effects of air moving over or around solid objects The Tacoma Narrows Bridge is a pair of mile-long Suspension bridges in the U It is therefore fortunate that the open truss structure supporting the deck is by its nature less subject to aerodynamic problems. Roebling designed a bridge and truss system that was six times as strong as he thought it needed to be. Because of this, the Brooklyn Bridge is still standing when many of the bridges built around the same time have vanished into history and been replaced. This is also in spite of the substitution of inferior quality wire in the cabling supplied by the contractor J. Lloyd Haigh — by the time it was discovered, it was too late to replace the cabling that had already been constructed. Roebling determined that the poorer wire would leave the bridge four rather than six times as strong as necessary, so it was eventually allowed to stand, with the addition of 250 cables. Diagonal cables were installed from the towers to the deck, intended to stiffen the bridge. They turned out to be unnecessary, but were kept for their distinctive beauty.

After the collapse of the I-35W highway bridge in the city of Minneapolis, increased public attention has been brought to bear on the condition of bridges across the US, and it has been reported that the Brooklyn Bridge approach ramps received a rating of "poor" at its last inspection [9]. The I-35W Mississippi River bridge (officially known simply as Bridge 9340) was an eight-lane steel Truss arch bridge that carried Interstate 35W across According to a NYC Department of Transportation spokesman, "The poor rating it received does not mean it is unsafe. Poor means there are some components that have to be rehabilitated. ” A $725 million project to replace the approaches and repaint the bridge is scheduled to begin in 2009. [10]

Later changes in use

At various times, the bridge has carried horse-drawn and trolley traffic; at present, it has six lanes for motor vehicles, with a separate walkway along the centerline for pedestrians and bicycles. A pedestrian is a person travelling on foot whether Walking or Running. The bicycle, cycle, or bike is a pedal-driven, human-powered vehicle with two wheels attached to a frame, one behind Due to the roadway's height (11 feet posted) and weight (6,000 lb posted) restrictions, commercial vehicles and buses are prohibited from using this bridge. The two inside traffic lanes once carried elevated trains of the BMT from Brooklyn points to a terminal at Park Row.

A tram, tramcar, trolley, trolley car, or streetcar is a railborne vehicle, of lighter weight and construction than a Train In 1950 the streetcars also stopped running, and the bridge was rebuilt to carry six lanes of automobile traffic.

After initially classifying the murder as one committed out of road rage, the FBI reclassified the case in 2000 as a terrorist attack. Road rage is the behavior by a driver of an automobile or other motor vehicle which thus causes collisions or incidents on roadways The entrance ramp to the bridge on the Manhattan side was named the Ari Halberstam Memorial Ramp in memory of the victim[11].

The 2003 Plot

In 2003, truck driver Iyman Faris was sentenced to about 20 years in prison for providing material support to al-Qaeda, after an earlier plot to destroy the bridge by cutting through its support wires with blowtorches was cancelled. Iyman Faris aka Mohammad Rauf (b on 4 June 1969 in Kashmir) is a former Truck driver from Columbus Ohio who Al-Qaeda, alternatively spelled al-Qaida, al-Qa`ida or al-Qa`idah, ( Arabic:; ar-Latn ''al-qāʿidah'' Translation: The The meaning of " blowtorch " varies between Britain and the USA [12]

Pedestrian access

The Brooklyn Bridge is accessible from the Brooklyn entrances of Tillary/Adams Streets, Sands/Pearl Streets, and Exit 28B of the eastbound Brooklyn-Queens Expressway. The Brooklyn Queens Expressway ( BQE) is an Expressway which runs from southern Brooklyn, New York to the Grand Central Parkway In Manhattan, motor cars can enter from either direction of the FDR Drive, Park Row, Chambers/Centre Streets, and Pearl/Frankfort Streets. The Franklin D Roosevelt East River Drive (commonly referred to as the FDR Drive) is a Freeway -standard Parkway on the east side of the New York Pedestrian access to the bridge from the Brooklyn side is from either Tillary/Adams Streets (in between the auto entrance/exit), or a staircase on Prospect St between Cadman Plaza East and West. In Manhattan, the pedestrian walkway is accessible from the end of Centre Street, or through the unpaid south staircase of Brooklyn Bridge-City Hall IRT subway station. Brooklyn Bridge–City Hall is a station on the IRT Lexington Avenue Line of the New York City Subway. The Interborough Rapid Transit Company (IRT was the operator of the original underground New York City Subway line that opened in 1904 as well as earlier Elevated railways The Brooklyn Bridge has a wide pedestrian walkway open to walkers and cyclists, in the center of the bridge and higher than the automobile lanes. While the bridge has always permitted the passage of pedestrians across its span, its role in allowing thousands to cross takes on a special importance in times of difficulty when usual means of crossing the East River have become unavailable.

During transit strikes by the Transport Workers Union in 1980 and 2005 the bridge was used by people commuting to work, with Mayors Koch and Bloomberg crossing the bridge as a gesture to the affected public. Strike action, often simply called a strike, is a work stoppage caused by the mass refusal by Employees to perform work. Edward Irving Koch (born December 12, 1924;) was a United States Congressman from 1969 to 1977 and the Mayor of New York City from 1978 to 1989 Michael Rubens Bloomberg (born February 14, 1942) is an American businessman and the Mayor of New York City.

Following the 1965, 1977 and 2003 Blackouts and most famously after the September 11, 2001 attacks on the World Trade Center, the bridge was used by people in Manhattan to leave the city after subway service was suspended. The Northeast Blackout of 1965 was a significant disruption in the supply of electricity on November 9, 1965, affecting Ontario, Canada The Northeast Blackout of 2003 was a massive widespread Power outage that occurred throughout parts of the Northeastern and Midwestern United States A power outage (also known as power cut, power failure, power loss, or blackout) is the loss of the Electricity supply to an The World Trade Center in New York City, United States (sometimes informally the WTC or Twin Towers) was a complex of seven buildings in Lower Manhattan The massive numbers of people on the bridge could not have been anticipated by the original designer, yet John Roebling designed it with three separate systems managing even unanticipated structural stresses. The bridge has a suspension system, a diagonal stay system, and a stiffening truss. "Roebling himself famously said if anything happens to one of [his] systems, 'The bridge may sag, but it will not fall. '"[16] The movement of large numbers of people on a bridge creates pedestrian oscillations or "sway" as the crowd lifts one foot after another, some falling inevitably in synchronized cadences. The natural sway motion of people walking causes small sideways oscillations in a bridge, which in turn cause people on the bridge to sway in step, increasing the amplitude of the bridge oscillations and continually reinforcing the effect. This high-density traffic causes a bridge to appear to move erratically or "to wobble" as happened at opening of the London Millennium Footbridge in 2000. The London Millennium Footbridge is a pedestrian-only steel Suspension bridge crossing the River Thames in London, England, linking [17]

Cultural significance

Contemporaries marveled at what technology was capable of and the bridge became a symbol of the optimism of the time. John Perry Barlow wrote in the late 20th century of the "literal and genuinely religious leap of faith" embodied in the Brooklyn Bridge … the Brooklyn Bridge required of its builders faith in their ability to control technology. John Perry Barlow (born October 3, 1947) is an American Poet, Essayist, retired Wyoming cattle rancher political "[18]

References to "selling the Brooklyn Bridge" abound in American culture, sometimes as examples of rural gullibility but more often in connection with an idea that strains credulity. For example, "If you believe that, I have a wonderful bargain for you…" References are often nowadays more oblique, such as "I could sell you some lovely riverside property in Brooklyn . . . ". George C. Parker and William McCloundy are two early 20th-century con-men who had (allegedly) successfully perpetrated this scam on unwitting tourists. George Parker (1870-1936 was one of the most audacious con men in American history William McCloundy was an early 20th-century Confidence trickster who served a two-and-a-half-year prison term in Sing Sing for selling the Brooklyn Bridge [1]

In his second book The Bridge, Hart Crane begins with a poem entitled "Poem: To Brooklyn Bridge. Harold Hart Crane ( July 21, 1899 – April 27, 1932) was an American Poet. " The bridge was a source of inspiration for Crane and he owned different apartments specifically to have different views of the bridge.

In the 1972 film, The Hot Rock, the Brooklyn Bridge was shown as a visual icon of New York City. The Hot Rock ( 1972) is a sly comic caper movie directed by Peter Yates, starring Robert Redford, George Segal, and Moses The partially-finished World Trade Center was also shown. The World Trade Center in New York City, United States (sometimes informally the WTC or Twin Towers) was a complex of seven buildings in Lower Manhattan In the years between 1972 and 2001, the WTC became the icon of choice for New York City, and use of the Brooklyn Bridge fell. Since 2001, the Brooklyn Bridge has been restored to its status of "If you see the Brooklyn Bridge, you know you're looking at New York City. "
