There was a little bit of fanfare, but the newly built $6.4-billion eastern span of the San Francisco-Oakland Bay Bridge has reopened to the public after more than a decade of construction delays. The new span replaces a structure that was damaged during the 1989 Loma Prieta earthquake.

It is designed to withstand the strongest earthquake estimated by seismologists to occur at the site over a 1,500-year period. Most modern Bay Area buildings other than schools and hospitals are designed for a 500-year time frame, but the Bay Bridge is reportedly built for those motions seismologists expect to occur once every 1,500 years.
