But as esthetically impressive as the $6.4 billion new span may be, its graceful looks overshadow its main mission: to not only remain standing after a devastating earthquake but to be able to carry emergency vehicles and supplies across the bay soon after the ground stops shaking.

Seismic engineers who designed the span used a variety of innovative techniques - some borrowed from offshore construction - to help make the bridge strong, yet flexible enough to withstand the greatest seismic forces imaginable.
