John A. Roebling Suspension Bridge, also known as the Covington and Cincinnati Bridge but renamed in 1984 after its designer
John A. and Washington Roebling
1856-67
This bridge was designed and constructed at a time when Cincinnati was a leading inland port. Ferry traffic across the River necessitated a bridge but support piers had to be kept to a minimum and the deck had to be high in order to permit boat track and the clearance of steamboat stacks. When the bridge was completed--an engineering feat, it was the world's longest suspension bridge and the "first to use vertical suspenders and diagonal stays fanning from either tower" (Cincinnati Transit website). These engineering techniques were next seen in Roebling's Brooklyn Bridge.
