Workers began tearing down the east span of the old Bay Bridge on Tuesday, nearly two months after the new bridge opened.  The demolition of the old bridge is expected to be a long, tedious process.  Construction workers will have to dismantle the bridge piece by piece.  According to one of the California Department of Transportation’s bridge engineers,  “the old bridge is the world’s largest armed bow and arrow. We have to de-string it very carefully or it will go boom.”  The $281 million demolition project is expected to take three years to complete.  This cost was already incorporated into the $6.4 billion price tag for the new bridge.  The 1.97 mile long east span opened in 1936 and is made of almost 59,000 tons of steel and 245,000 tons of concrete.  The majority of the steel will be recycled or reused, but some will be saved for a new park commemorating the old bridge.  The following link contains a great slideshow of construction crews beginning the demolition of  the bridge.
