San Francisco-Oakland Bay Bridge - TechKnow

San Francisco, California is an earthquake-prone area. Engineers there are now developing new technologies that create structures that could absorb the impact of an earthquake, while leaving the rest of the structure in-tact.

The technology was inspired by car crash crumple zones, a safety feature, often at the front of a car. And the idea has inspired engineers to design the world's widest bridge with sections that could absorb earthquake damage.
