Walk, jog, or run across this bridge for light exercise, a great view and local history. Upon opening in 1866, it was the longest suspension bridge in the world and a feat of engineering. Architect Daniel Roebling's most famous bridge connects lower Manhatten to Brooklyn, but he started in Cincinnati before he built the Brooklyn Bridge. This suspension bridge was a crucial link between North and South and a controversial one at times during the war. The deck of the bridge is made of metallic mesh, which causes friction with radial tires and earned the structure the nickname, Singing Bridge.
Shortly after construction was complete, residents on the Ohio and Kentucky sides were skeptical of the structure's soundness, often refusing to cross. Roebling needed to do something to change the perception so he called upon the greatest self promoter in Cincinnati to help him out. P.T. Barnum marched more than 300 elephants across the bridge in front of the press and skeptical residents, quelling any lingering concerns.
