One hundred sixty-six thousand people walked across the new suspension bridge in its first two days -- at a penny per pedestrian. The structure they crossed had taken over a decade to build, survived threats of Confederate invasion, and consumed one million pounds of wire imported from Manchester, England, because its designer did not trust American steel. That designer was John A. Roebling, a German-born engineer who would stake his reputation on the idea that a suspension bridge could carry real traffic over a major river. The bridge linking Cincinnati, Ohio, to Covington, Kentucky, was his proof of concept. When it formally opened on January 1, 1867, it was the longest suspension bridge in the world. Roebling's next project would be the Brooklyn Bridge.

In September 1865, workers laid the first two wire ropes by unwinding them from a spool mounted on a barge, letting them sink to the riverbed, then raising them in unison. A crude footbridge was strung for the workers. Then began ...

The diagonal stay cables that Roebling added to stiffen the deck and dampen vibration were an innovation he would carry directly to his design for the Brooklyn Bridge, begun just two years l...

Three horses and a carriage cost a quarter. Pedestrians paid one cent. Streetcars ran across its deck for decades until servic...

John A. Roebling Suspension Bridge: A River That Changed Around It

The hundred-foot vertical clearance was dictated not by water but by steamboats, whose tall stacks needed room to pass beneath without showering sparks onto wooden hulls. As railroads replaced river...
