Brooklyn Bridge

Here are some photos and background of the grand Brooklyn Bridge.
The Brooklyn Bridge is a bridge in New York City and is one of the oldest suspension bridges in the United States. Completed in 1883, it connects the boroughs of Manhattan and Brooklyn by spanning the East River. With a main span of 1,595.5 feet (486.3 m), it was the longest suspension bridge in the world from its opening until 1903, and the first steel-wire suspension bridge.

Originally referred to as the New York and Brooklyn Bridge and as the East River Bridge, it was dubbed the Brooklyn Bridge, a name from an earlier January 25, 1867, letter to the editor of the Brooklyn Daily Eagle, and formally so named by the city government in 1915...

The Brooklyn Bridge was initially designed by German immigrant John Augustus Roebling, who had previously designed and constructed shorter suspension bridges, such as Roebling's Delaware Aqueduct in Lackawaxen, Pennsylvania, Waco Suspension Bridge in Waco, Texas, and the John A. Roebling Suspension Bridge in Cincinnati, Ohio.

...While conducting surveys for the bridge project, Roebling sustained a crush injury to his foot...which left him incapacitated and soon resulted in his death, not long after he had placed his 32-year-old son Washington Roebling in charge of the project.

Washington Roebling also suffered a paralyzing injury as a result of decompression sickness shortly after the beginning of construction on January 3, 1870. [U]nable to physically supervise the construction firsthand, his wife Emily Warren Roebling stepped in and provided the critical written link between her husband and the engineers on site. Under her husband's guidance, Emily studied higher mathematics, the calculations of catenary curves, the strengths of materials, bridge specifications, and the intricacies of cable construction. She spent the next 11 years assisting Washington Roebling helping to supervise the bridge's construction...

The towers are built of limestone, granite, and Rosendale cement. The granite blocks were quarried and shaped on Vinalhaven Island, Maine, under a contract with the Bodwell Granite Company, and delivered from Maine to New York by schooner.

The Brooklyn Bridge was opened for use on May 24, 1883. The opening ceremony was attended by several thousand people and many ships were present in the East Bay for the occasion. President Chester A. Arthur and New York Mayor Franklin Edson crossed the bridge to celebratory cannon fire and were greeted by Brooklyn Mayor Seth Low when they reached the Brooklyn-side tower...

At the time it opened, and for several years, it was the longest suspension bridge in the world—50% longer than any previously built—and it has become a treasured landmark....

The architectural style is neo-Gothic, with characteristic pointed arches above the passageways through the stone towers. The paint scheme of the bridge is "Brooklyn Bridge Tan" and "Silver", although it has been argued that the original paint was "Rawlins Red."
