Opened in , the Brooklyn Bridge was the first fixed crossing across the East River. It is toll-free. A brilliant feat of 19th-century engineering, the Brooklyn Bridge was the first bridge to use steel for cable wire, and during its construction explosives were used inside a pneumatic caisson for the first time.
A brilliant feat of 19th-century engineering, the Brooklyn Bridge was the first bridge to use steel for cable wire, and during its construction explosives were used inside a pneumatic caisson for the first time. Since its construction, the bridge has become an essential landmark of New York City—an outstanding architectural accomplishment that is what is sangria in spanish revered across the world.
Accordingly, it has been designated a National Historic Landmark by the U. National Park Service. The masterwork of John Augustus Roeblingthe Brooklyn Bridge was built —83 in the face of immense difficulties. Roebling, an engineer, had developed his own method for weaving wire cables, which became one of the leading constructional components of his bridge designs. He built a series of suspension bridges, including the Cincinnati—Covington Bridge, later renamed the John A.
Roebling Bridge. Confined to his apartment in Columbia Heights BrooklynRoebling continued to direct operations with the help of his wife, Emily Warren Roeblingobserving with field glasses and sending messages to the site with her assistance. A compressed-air blast that wrecked a pneumatic caisson slowed the work, as did a severe fire that smoldered for weeks in another caisson, a cable that parted from its anchorage on the Manhattan side and crashed into the river, and the fraud perpetrated by a steel-wire contractor that necessitated the replacement of tons of cable.
At least 20 workers were killed during construction, and many more suffered decompression sickness. The towers are built of limestonegraniteand cement. Its deck, supported by four cables, carries both automobile and pedestrian traffic. Upon its completion, Emily rode the first carriage across from the Brooklyn side, carrying a rooster as a symbol of victory. Chester A. The building of it came to represent a landmark in technological achievement for a generation.

The real Brooklyn Bridge has some subtle slope transitions that are difficult to model in Lego at this scale. Rather than flattening out the angles, which would have resulted in one big rectangular block, I chose to exaggerate them, like a caricature, in order to preserve their essence.

Of all the engineering advances in the s, the Brooklyn Bridge stands out as perhaps the most famous and most remarkable. It took more than a decade to build, cost the life of its designer, and was constantly criticized by skeptics who predicted the entire structure was going to collapse into New York's East River.
When it opened on May 24, , the world took notice and the entire U. The great bridge, with its majestic stone towers and graceful steel cables, isn't just a beautiful New York City landmark. It's also a very dependable route for many thousands of daily commuters. John Roebling , an immigrant from Germany, did not invent the suspension bridge, but his work building bridges in America made him the most prominent bridge builder in the U.
His bridges over the Allegheny River at Pittsburgh completed in and over the Ohio River at Cincinnati completed were considered remarkable achievements. Roebling began dreaming of spanning the East River between New York and Brooklyn which were then two separate cities as early as when he drew designs for enormous towers that would hold the bridge's cables.
The Civil War put any such plans on hold, but in the New York State legislature chartered a company to build a bridge across the East River. Roebling was chosen as its chief engineer. Just as work was beginning on the bridge in the summer of , tragedy struck. John Roebling severely injured his foot in a freak accident as he was surveying the spot where the Brooklyn tower would be built. He died of lockjaw not long after, and his son Washington Roebling , who had distinguished himself as a Union officer in the Civil War, became chief engineer of the bridge project.
Talk of somehow bridging the East River began as early as , when large bridges were essentially dreams. The advantages of having a convenient link between the two growing cities of New York and Brooklyn were obvious.
The East River is actually a saltwater estuary , prone to turbulence and tidal conditions. Further complicating matters was the fact that the East River was one of the busiest waterways on earth, with hundreds of crafts of all sizes sailing on it at any time.
Any bridge spanning the water would have to allow for ships to pass beneath it, meaning a very high suspension bridge was the only practical solution. And the bridge would have to be the largest bridge ever built, nearly twice the length of the famed Menai Suspension Bridge, which had heralded the age of great suspension bridges when it opened in Perhaps the greatest innovation dictated by John Roebling was the use of steel in the construction of the bridge.
Earlier suspension bridges had been built of iron, but steel would make the Brooklyn Bridge much stronger. Compressed air was pumped into them, and men inside would dig away at the sand and rock on the river bottom. The stone towers were built atop the caissons, which sank deeper into the river bottom. Washington Roebling, who went into the caisson to oversee work, was involved in an accident and never fully recovered.
An invalid after the accident, Roebling stayed in his house in Brooklyn Heights. His wife Emily, who trained herself as an engineer, would take his instructions to the bridge site every day. Rumors thus abounded that a woman was secretly the chief engineer of the bridge. After the caissons had been sunk to the river bottom, they were filled with concrete, and the construction of the stone towers continued above. When the towers reached their ultimate height, feet above high water, work began on the four enormous cables that would support the roadway.
Spinning the cables between the towers began in the summer of , and was finished a year and four months later. But it would take nearly another five years to suspend the roadway from the cables and have the bridge ready for traffic. There were stories of political payoffs and corruption, rumors of carpet bags stuffed with cash being given to characters like Boss Tweed , the leader of the political machine known as Tammany Hall. In one famous case, a manufacturer of wire rope sold inferior material to the bridge company.
The shady contractor, J. Lloyd Haigh, escaped prosecution. While no official figures were kept on how many men died building the bridge, it has been reasonably estimated that about 20 to 30 men perished in various accidents. The grand opening for the bridge was held on May 24, Some Irish residents of New York took offense as the day happened to be the birthday of Queen Victoria , but most of the city turned out to celebrate.
President Chester A. Arthur came to New York City for the event, and led a group of dignitaries who walked across the bridge. Military bands played, and cannons in the Brooklyn Navy Yard sounded salutes. A number of speakers lauded the bridge, calling it a "Wonder of Science" and lauding its anticipated contribution to commerce.
The bridge became an instant symbol of the age. Its early years are the stuff of both tragedy and legend , and today, nearly years since its completion, the bridge functions every day as a vital route for New York commuters. And while the roadway structures have been changed to accommodate automobiles, the pedestrian walkway is still a popular attraction for strollers, sightseers, and tourists. Share Flipboard Email.
