Haunched single-span bridges (HSSBs) are used where an aesthetically pleasing graceful shape is desired and/or the vertical clearance needs to be maximized. After a brief introduction into simple-span bridges with short cantilever extensions, the article provides a complete design example for a post-tensioned concrete box girder HSSB. The design example is presented as a simple six-step procedure. These bridges are relatively easy to design, even for novice bridge designers.
