Abstract: The Overhead Cable System (OCS) serves as the main anchorage system of the Bridge Supplemental Set and is used to hold the Improved Ribbon Bridge (IRB) against river flow. Several improvements have been made to OCS components and employment procedures, theoretically allowing the OCS to operate safely within most environments. However, the modernized OCS had yet to be constructed over an actual river, making it necessary to conduct a full-scale capability demonstration. Range W2 of Camp Ripley was selected as the test site because the 200th Multi-Role Bridge Company agreed to support the demonstration during an ongoing training cycle. A site reconnaissance trip revealed environmental obstacles on each bank, which made the site a unique test for the modernized OCS. The OCS model, a software package developed to analyze the loading imposed by river drag force on the OCS, was used to design a unique layout that circumvents Camp Ripley’s environmental challenges. The OCS was successfully deployed over Camp Ripley’s wet gap flowing at a river speed of 3.5 ft/s, and the IRB supported vehicular traffic for 3 hr before safe disassembly. Several lessons were learned regarding system deployment, and data were collected to facilitate technical manual development.
