San Francisco-Oakland Bridge Construction [Video]
Fascinating 4-minute time-lapse video of the new self-anchored suspension San Francisco-Oakland Bridge construction (October 2008 to August 2013)
The new Bay Bridge was launched on September 2, 2013. It is engineered to withstand a large earthquake and replaces the cantilevered section of the Bay Bridge which became the subject of concern after a section collapsed during the Loma Prieta earthquake on October 17, 1989.
The San Francisco-Oakland Bay Bridge, was first completed in 1936. The Bay Bridge consisted of two different types of bridges–suspension on the San Francisco side and cantilever on the Oakland side–connected via tunnel through Yerba Buena Island. The eastern portion has been replaced by a self-anchored suspension bridge and is the longest of its type in the world.
In 1955, the American Society of Civil Engineers declared the Bay Bridge the seventh wonder of the world.
