The Cumberland Flyover Bridge - A Shallow Curved Steel Girder Design ExampleWith the objective of improving flow and safety at the confluence of I-90 and I-190, the Cumberland Flyover spans over 850 feet, has a 656ft horizontal radius and 200+ foot spans. Curved steel plate girders were employed with a unique framing plan consisting of tighter girder spacing in the exterior bays to stiffen the bridge torsionally while keeping the girder depth shallow and meet vertical clearance requirements.
