"In 1978, SOM architect Myron Goldsmith and engineer T.Y. Lin created a remarkable structure to span the challenging middle fork of California’s American River. Ruck-A-Chucky Bridge elegantly solves the problem of building a stable, economical structure across a wide, steep gorge by entirely rethinking the principles of bridge building. A “hanging arc,” the bridge was to be suspended by 80 high-strength cables and balanced by tensile forces. Though unbuilt, Ruck-A-Chucky Bridge stands as a masterwork of innovative design and structural economy to this day."
