      Ausstrahlung: Mär 02, 2005
      In 1906, an earthquake of magnitude 7.9 rocked San Francisco. An earthquake of similar or greater proportions is expected to occur in San Francisco again, and soon. The episode takes a look at the efforts that are being made to retrofit and strengthen America’s most recognized bridge, the Golden Gate Bridge, before the next big earthquake happens. It also gives a brief history about the construction of the suspension bridge, and the people who were involved in its construction.
