Websupport skews between 0 and 60 degrees and for concrete bridges on curved alignments with support skews between 0 and 45 degrees. For the purpose of this memo, a bridge on a curved alignment can be considered to be on a straight alignment as long as its curvature effects can be ignored according to AASHTO-LRFD 4.6.1.2. Webfocuses on the design of the curved spans. The curved portion of the flyover is comprised of 7 continuous spans totaling 536 feet in length. The structure curves a total of 183 degrees, which results in a horseshoe shape. The horseshoe shape and sharp radius of curvature induces different behavior compared to a typical curved girder bridge.
