The Brooklyn Bridge’s construction is one of the great achievements in United States history.
The main design feature of the bridge were four 15 inch diameter steel cables that would
support the enormous expanse of the bridge, which was to be over 6000 feet
In order to support those cables, the towers had to be enormous and they had to be sunk to the bedrock
below the East River.The construction of the roadway began in 1878 and finally finished in 1882. By 1883,
the longest suspension bridge in the world was finished after thirteen years of development and construction.
