Summary: The last chunks of the old Bay Bridge eastern span will get a new life next year, when Caltrans transforms them into boardwalks — one jutting out from the Oakland shoreline near the toll plaza, the other at Yerba Buena Island. Three of the bridge’s original concrete piers will serve as foundations for those platforms. Caltrans will demolish the other two remaining piers on Saturday, Sept. 8, in a blast that will send bits of concrete and rebar to the bay floor.
