Watch a bubble curtain used in California pier explosion


Over the weekend, the largest of the piers of the San Francisco-Oakland Bay Bridge’s old east span was removed from the bay through a careful and extensively planned implosion.

In just six seconds, nearly 600 controlled charges weakened the 50-feet of Pier E3 which stood above the bay floor, allowing gravity to collapse the tower into its hallow casing below the mudline.

The pier is about as tall as a five-story building and has been outfitted with a wood and steel cage that will trap debris from the explosion that used 20,000 pounds of dynamite.
