U.S. Army Engineers demonstrate their capabilities utilizing the Improved Ribbon Bridge (IRB). The Improved Ribbon Bridge (IRB) enables Soldiers to cross rivers, lakes, or other bodies of water in the absence of a means of crossing or in the event of an unreliable or damaged permanent bridge. The IRB can be configured as either a continuous full-closure bridge or assembled and used for rafting operations.
