Pneumatic caissons sunk to a depth of forty-four feet on the Brooklyn side, and seventy-eight feet on the Manhattan side provided dry space for workers to dig footings for the bridge's foundation. Alas, working in the caisson often brought on "the bends" -- a serious medical condition caused by moving too quickly from a high-pressure atmosphere to a low-pressure atmosphere. Washington Roebling was among many workers permanently impaired by the then little understood "caisson disease."
The Brooklyn Bridge opened to citywide celebration on May 24, 1883. Over the next hundred years the bridge became part of the romance of New York City. Poets and artists have long found the bridge a worthy subject. The Brooklyn Bridge continues to serve as the backdrop in countless photographs and films. It plays roles both real and fanciful in the American memory.
