The current Brooklyn Bridge was conceived by German immigrant John Augustus Roebling in 1852. Eine Brücke ohne störende Pfeiler, die den Meeresarm weit über den Schiffsmasten in einer großen Spanne überquert, wäre die ideale Lösung gewesen, schien aber damals jenseits aller technischen Möglichkeiten zu sein.  Two months later, the New York and Brooklyn Bridge Company was incorporated with a board of directors (later converted to a board of trustees).

Welche Insider-Spots ihr unbedingt ansehen müsst und welche tollen Touren es gibt, zeigen wir euch in diesem Artikel! Crossbeams run between the trusses at the top, and diagonal and vertical stiffening beams run on the outside and inside of each roadway. It is the result of the study, of the experience, and of the knowledge of many men in many ages. Duffy jumped and was not seen again. , In August 2016, after the renovation had been completed, the NYCDOT announced that it would conduct a seven-month, $370,000 study to verify if the bridge could support a heavier upper deck that consisted of an expanded bicycle and pedestrian path. , The construction of the Brooklyn Bridge is detailed in numerous media sources, including David McCullough's 1972 book The Great Bridge and Ken Burns's 1981 documentary Brooklyn Bridge.
