There are six bridges that cross the Ohio River, from Cincinnati’s metro area to northern Kentucky. The oldest, and most famous, is the Roebling Suspension Bridge—confirmed by the fact that there were three photographers, including myself, happily shooting that day.
The bridge is named for its creator, John A. Roebling. He was born in Prussia in 1806 but, after the Napoleonic Wars, there was little funding for infrastructure so he and his brother, Carl, moved to the US. They first built canal bridges, followed by three suspension bridges around Pittsburg.
Then they turned their sights toward Cincinnati. When the bridge opened on December 1, 1866, it was the longest suspension bridge in the world at 1,057 feet (322 meters) main span. It’s nicknamed the “singing bridge” because you can hear the hum of cars passing underneath.
The Roebling brothers also designed the Brooklyn Bridge but John received an injury during the construction, which later became infected, resulting in his death in 1869. His son, Washington, completed the bridge in 1883.
