Desc: DEMO: Bay Bridge: Directed by Sam Burbank. A New Bay Bridge has replaced San Francisco Bay's iconic East Span, but the trickiest job is yet to come - safely taking down the original, 80-year-old span. It sits just an arm's length from the new bridge. It's a construction project of a lifetime. Technically challenging and vast in scope, over two miles of steel and concrete. Join the men and women on the front lines for this unique project.
