History of Brooklyn Bridge

/kloc-In the middle of the 9th century, new york was the fastest-growing city in the world at that time, and some people planned to build the longest bridge ever to connect Manhattan and Brooklyn.

It was German immigrant John Roblin who first proposed the Brooklyn Bridge. He was a student of Hegel and later became an architect. John Roblin called for 65,438+05 years to build the bridge. According to his design, Brooklyn Bridge was 1.600 meters long, which was the longest bridge in the world at that time and the first cable-stayed suspension bridge in the world. The planned construction period is 14 years.

1869, shortly before the Brooklyn bridge started, John Roblin suffered from tetanus. He stubbornly refused the doctor's treatment and passed away. The heavy responsibility of building the bridge fell to his 32-year-old son, Washington Roblin, who became the chief engineer.

Washington Roblin insisted on visiting the site from the beginning of the bridge construction, but the underwater construction of the bridge piles made Washington suffer from serious "diver's disease". By the time the two bridge piles were completed, Washington was seriously ill and paralyzed, unable to reach the construction site in person. From then on, Washington may be the strangest person in the history of architecture. Every day, he observed the construction of the bridge with a telescope on his windowsill, and then dictated various instructions, which were recorded by his wife Emily and handed over to the builders. His wife Emily had to teach herself advanced mathematics and other engineering skills, and assumed the dual roles of nurse and assistant to the chief engineer.

One year before the completion of the bridge, some people began to question whether it was appropriate to hand over such a huge project to a patient. Some people even suspect that Washington has gone crazy. The board of directors intends to replace the chief engineer. His wife Emily mobilized the public to support her husband and personally delivered a speech to the American Society of Civil Engineers. It is the first time for a woman to give a speech in the male field of a major industrial project. After the speech, the board of directors voted, and the result of 7: 1 let Washington continue to be the chief engineer.

In the past 1882 and 12, the bridge was completed and opened to traffic. On that day,150,000 people took to the bridge deck to hold a celebration ceremony, but the young Roblin did not show up. His builder, Washington Roblin, never set foot on this bridge built by two generations, and his wife, Emily, was commended by the board of directors.

Today, between Manhattan Island and Brooklyn, there is a suspension bridge across the East River, called Brooklyn Bridge. Brooklyn Bridge was built in 1883, and its appearance is rich and elegant. Towers and steel cables are the objects that painters compete to describe. This bridge, together with the Empire State Building and the former World Trade Center Twin Towers, has always been a landmark building in new york, and the legendary story of the engineer Roblin's family of two generations and three people has added gorgeous luster to this bridge.

Brooklyn Bridge was designed and built by Roblin Sr., but just three months after it was built, Roblin Sr. died of tetanus. At the age of 32, young Roblin inherited his father's ambition and continued to work underwater for a long time. Three years later, he was paralyzed by diving. From then on, he sat in front of the window sill at home and guided every project with a telescope. Little Roblin's wife Emily is even more unusual. In order to accurately convey her husband's instructions to the workers, she taught herself advanced mathematics, mechanics, bridge science and other courses, and traveled to and from the construction site and home every day to assume the actual command responsibility of bridge engineering. When the bridge was first built, it was mainly used for people to cross the East River on foot or horseback. Later, a tram track was added. By 1950, the bridge needs to be rebuilt, adding six lanes for vehicles, and the trams will be stopped during the reconstruction. May 24th, 2008 is the 25th anniversary of the completion of Brooklyn Bridge/KLOC-0. On the 22nd, there will be a five-day celebration.
