New York City Brooklyn Bridge   Currier & Ives 1877


The Brooklyn Bridge opened to great fanfare in May 1883. The names of John Roebling, Washington Roebling, and Emily Warren Roebling are inscribed on the structure as its builders.

Construction began on January 3, 1870. The Brooklyn Bridge was completed thirteen years later and was opened for use on May 24, 1883. The Brooklyn Bridge might not have been built had it not been for Emily Warren Roebling

 as the bridge’s builders. Early into construction in 1872, however, collapsing bridge timbers crushed John Roebling’s legs, leaving him incapacitated. Soon after, an illness paralyzed Washington Roebling. With both men out of commission, Emily Warren Roebling took over. Under her husband’s guidance, Emily had 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 supervising the bridge’s construction.

. Further festivity included the performance of a band, gunfire from ships, and a fireworks display.

On that first day, a total of 1,800 vehicles and 150,300 people crossed what was then the only land passage between Manhattan and Long Island. The bridge's main span over the East River is 1,595 feet 6 inches (486.3 m). The bridge cost $15.5 million to build and approximately 27 people died during its construction.

One week after the opening, on May 30, 1883, a rumor that the Bridge was going to collapse caused a stampede, which crushed and killed twelve people. On May 17, 1884, P. T. Barnum helped to squelch doubts about the bridge's stability—while publicizing his famous circus—when one of his most famous attractions, Jumbo

 (Galloping Gertie) in 1940. It is therefore fortunate that the open truss structure supporting the deck is by its nature less subject to aerodynamic problems. Roebling designed a bridge and truss system that was six times as strong as he thought it needed to be. Because of this, the Brooklyn Bridge is still standing when many of the bridges built around the same time have vanished into history and been replaced. This is also in spite of the substitution of inferior quality wire in the cabling supplied by the contractor J. Lloyd Haigh — by the time it was discovered, it was too late to replace the cabling that had already been constructed. Roebling determined that the poorer wire would leave the bridge four rather than six times as strong as necessary, so it was eventually allowed to stand, with the addition of 250 cables. Diagonal cables were installed from the towers to the deck, intended to stiffen the bridge. They turned out to be unnecessary, but were kept for their distinctive beauty.

After the collapse of the I-35W highway bridge in the city of Minneapolis, increased public attention has been brought to bear on the condition of bridges across the US, and it has been reported that the Brooklyn Bridge approach ramps received a rating of "poor" at its last inspection. According to a NYC Department of Transportation spokesman, "The poor rating it received does not mean it is unsafe. Poor means there are some components that have to be rehabilitated.” A $725 million project to replace the approaches and repaint the bridge is scheduled to begin in 2009.

, the bridge was used by people in Manhattan to leave the city after subway service was suspended. The massive numbers of people on the bridge could not have been anticipated by the original designer, yet John Roebling designed it with three separate systems managing even unanticipated structural stresses. The bridge has a suspension system, a diagonal stay system, and a stiffening truss. "Roebling himself famously said if anything happens to one of [his] systems, 'The bridge may sag, but it will not fall.'" The movement of large numbers of people on a bridge creates pedestrian oscillations or "sway" as the crowd lifts one foot after another, some falling inevitably in synchronized cadences. The natural sway motion of people walking causes small sideways oscillations in a bridge, which in turn cause people on the bridge to sway in step, increasing the amplitude of the bridge oscillations and continually reinforcing the effect. This high-density traffic causes a bridge to appear to move erratically or "to wobble" as happened at opening of the London Millennium Footbridge
