OAKLAND - Extensive preparations are underway in the San Francisco Bay as Caltrans works to put the final pieces in place to implode Pier E3 of the old Bay Bridge on Nov. 14. As the largest of the marine foundations that once held the now decommissioned eastern span of the Bridge, this operation is the equivalent of taking down a five-story building but entirely underwater.

In this Caltrans News Flash, Bay Bridge spokesperson Leah Robinson-Leach details the innovative technologies in place to remove the pier in the most environmentally sound and efficient way possible. Also, get a behind-the-scenes, or rather under-the-surface, glimpse at the unique "bubble curtain" that will absorb about 80 percent of the shock wave from the implosion.
