The Brooklyn Bridge has a steel frame surrounded by concrete.
Manhattan and Brooklyn are connected by the Brooklyn Bridge, a hybrid suspension/cable-stay bridge in New York City. With its completion in 1883, it ranks among the earliest suspension bridges in the United States and was the first steel-wire suspension bridge ever built. John Augustus Roebling created the Brooklyn Bridge. He was measuring across the East River ferry when he stomped his foot against a piling.
After having his foot removed, he contracted tetanus, went into a coma, and passed away from the disease 3 weeks later, just a few days after appointing his son Washington Roebling to oversee the bridge's construction. On January 3, 1870, work commenced. The public could cross the Brooklyn Bridge on May 24, 1883.
