Best Non-highway Bridge Cowinner - David Kreitzer Lake Hodges Bridge, San Diego, Calif.

This unique bicycle/pedestrian bridge is the worlds longest stress-ribbon bridge. The stress-ribbon bridge is a type of suspension bridge with cables embedded in an ultra-thin concrete deck. This type of bridge is rare, with only six examples in North America and fewer than 50 worldwide. The stress-ribbon type was selected to minimize environmental impacts and because it works well aesthetically in both wet and dry lake conditions. Since the superstructure was constructed of precast concrete panels suspended from cables, there was no need for falsework, which could have caused sever damage to the park. The visual impact was minimized with a 16 in. deck and 330 ft spans, limiting the number of piers in the lake to two. The stress-ribbon design resulted in an economical, durable, and signature structure for the area while minimizing impacts to biological and cultural resources. This innovative precast concrete solution eliminated a 9 mi trail detour and provides a safe route for bicycle commuters.
