Testing the limits of the Improved Ribbon Bridge
Dr. Duncan Bryant, a research hydraulic engineer with the U.S. Army Engineer Research and Development Center’s (ERDC) Coastal and Hydraulics Laboratory, observes a model tank crossing a scale model of the Improved Ribbon Bridge (IRB), Feb. 24, 2022. Researchers at the ERDC are using physical modeling as part of an effort to test the high military load capacity vehicle weight limits of the IRB to determine under what operational conditions they can safely cross.
