Longest Stress Ribbon Bridge Takes Shape In San Diego
Foundation work is almost complete on a 990-ft-long stress ribbon bridge over San Diego County’s Lake Hodges. When finished in March 2009, the $10.3-million footbridge will be the world’s longest of its type, says Wade Durant, resident engineer with San Francisco-based T.Y. Lin International, the designer.
San Dieguito River Park, the project owner, went with a stress ribbon bridge in part because its 12-ft-wide design will have minimal ecological and visual impact. “We could have built a conventional bridge cheaper, but it might never have got approved by environmental agencies because of [so] many foundations across the lake,” Durant says.
