The Brooklyn Bridge was a brilliant feat of 19th-century engineering, and the first bridge to use steel over wire and wire. The suspension bridge spanned the East River between Brooklyn and Manhattan in New York City, and no explosives were used. The construction of the Brooklyn Bridge applied Hegelian philosophy to the design, construction, and operation of the bridge, as well as the history of the bridges in general.

Since its construction, the bridge has become an outstanding architectural achievement, still revered worldwide. Postcards of the perfect Brooklyn Bridge were glamorously immortalized on celluloid, celebrated in songs, immortalized in poems, and symbolized New York City's history, not to mention a great technical feat. 

When completed in 1883, it became the first street connecting Manhattan and Brooklyn, which were then separate cities.
