This is the world’s longest stress ribbon bridge. Only six other examples exist in North America and fewer than 50 worldwide. A stress ribbon bridge is essentially a suspension bridge with bearing cables embedded within the concrete deck. The bridge is 990 feet between abutments, with three equal spans and a 16-inch-thick deck. Commissioned by the San Dieguito River Park Joint Powers Authority, the bridge connects two separate portions of an existing trail system that crosses a protected habitat. The stress ribbon design was selected due to its thin profile and the need for only two concrete piers. The design also provides a highly dramatic and graceful bridge. During rainy seasons the bridge appears to float on the lake, while during periods of drought, it is nestled within the landscape.
