It was amazing to drive over the East River that connects the boroughs of Manhattan and Brooklyn in New York City. Obviously it's the Brooklyn Bridge. It is nice to visit during the day but looks more beautiful and glamorous at night. The Brooklyn Bridge is one of the oldest bridges in the United States that attracts visitor attraction. This is a great achievement for the United States, completed in early 1883 after 14 years of hard work. The most important thing is that it is the first steel wire suspension bridge. It is a safe passage for millions of travelers, tourists, trains, cars, bicycles and other modes of transportation. Because of its exceptional historical significance, in 1964, it was designated a National Historic Landmark and a National Historic Civil Engineering Landmark. About 600 workers were involved in the construction, and the total cost at that time was $15 million. Since it was built after the Civil War, when racism among people was very serious. The workers were actually poor and immigrant people. So they were paid a lot less, like $2 dollars for a day or something. They also worked in very uncomfortable situations, such as when it was very hot, in the rain, under water, which made many of them sick. They also get many types of normal or serious illnesses such as headaches, itchy skin, nosebleeds, and slow heartbeat. More than 100 workers suffered numbness, slurred speech, joint pain, paralysis, seizures, and some died. At that time there were much fewer safety rules for them. Their contribution made the construction of the bridge possible. When it opened on the first day, approximately 250,000 people passed through it and witnessed a great invention. A week after it opened, about 20,000 people were on the bridge when panic arose that the bridge was about to collapse. Then people started running and twelve people, along with many others, were crushed
