A vehicle from the contractor dismantling the old Bay Bridge drives off the span while a crew prepares an implosion of the E-3 pier in San Francisco, Calif. on Wednesday, Nov. 11, 2015. A demoliton team will detonate a number of charges below the surface of the bay to demolish the old piling on Saturday morning.
Blowing up the last pier of the old Bay Bridge will take just six seconds early Saturday morning.
