Summary
The challenges to build the new San Francisco Bay Bridge are huge. How to build a strong foundation when there's no bedrock, only a sea of mud that quivers like jello in an earthquake? How to construct a bridge that will bend but won't break? How to get it all finished before the next quake hits? Nothing like it has ever been built in a seismic zone.Monster equipment has been imported from all over the world with the most powerful cranes driving the tallest piles. With that huge scale, come the inevitable big problems and danger at every turn.PRODUCTION DETAILS:Produced by Barna-Alper Productions Inc. in association with Discovery Channel Canada
