    Caltrans demolished two piers of the San Francisco-Oakland Bay Bridge's old eastern span Saturday morning, officials said.

    The implosions took place underwater and removed piers E9 and E10.

    It was the third of this fall's six scheduled implosions for the demolition of the remaining 11 marine foundations of the original east span of the bridge. 

    Traffic breaks were expected anytime between 9 and 11 a.m., when the implosions were planned to take place, according to Caltrans. 

    The agency said it plans to finish the work by mid-November. Caltrans began demolishing the old eastern span in September 2013 after the new eastern span opened to traffic.

    Pier E3, which was the largest pier and the closest to Yerba Buena and Treasure islands, was removed in 2015 and piers E4 and E5 were removed in 2016.

    The remaining piers will be removed every other weekend through the second week in November, Caltrans officials said.

    By combining the demolition of multiple piers, when possible, Caltrans says it is poised to save $10 million in taxpayer money.

    Caltrans provided a livestream of the demolition online.
