From Three Spans to One with HPC

This paper describes how adjacent box girder bridges are frequently used in Ohio and other eastern states. These bridges have a favorable span-to-depth ratio—an important benefit when vertical clearance is a design consideration. Furthermore, with noncomposite sections the bridge can be constructed quickly because there is no need to form, cast, and cure a separate deck. With high performance concrete (HPC) adjacent box girders, savings can also be realized by using longer spans and eliminating piers. The Ohio HPC Showcase bridge is located on U.S. 22, near Cambridge, Ohio. The existing structure was a 70-ft (21.3-m) long steel stringer bridge over a river. The Ohio Department of Transportation (ODOT) decided to widen the channel at this point and to provide sloping sides, rather than the existing vertical sides. The original replacement structure was designed as a three-span bridge using 21-in. (535-mm) deep, simply-supported boxes.
