The Oakland - San Francisco Bay Bridge
The Bay Bridge is really two bridges, one an eastern span between Yerba Buena Island and Oakland, the other a western span between between the Island and San Francisco. The pier you are standing on is built on pilings that once supported the original eastern span.
The 1989 Loma Prieta Earthquake caused a portion of the upper eastern span deck to fail, providing a wake-up call: if a 6.9 earthquake centered sixty miles away could cause such damage, imagine what the largest earthquake predicted possible on the Hayward Fault, a 7.3 magnitude, centered only six miles away could do! There were many years planning a new, seismically secure suspension bridge for the eastern span. Built between 2002 and 2013, it cost around $6.5 billion-many times more than the $250 million originally estimated. Now over 100 million vehicles per year cross over this iconic landmark.
