A stress ribbon bridge is essentially a suspension bridge with bearing cables embedded within the concrete deck. Unlike the simple span the ribbon is stressed in compression, The advantages of the stressed ribbon style bridge are 1) that enables a long span (330 feet) between piers, so that there are only two piers in the lake; and 2) it has a narrow profile, only 16 inches deep.
