| Extreme Engineering unveils some of the most ambitious architectural plans of our times. Some are theoretical; others are in the works. But all of these modern marvels pose challenges that stretch the definition of what's possible. Watch as jaw-dropping computer animation and first-hand accounts from builders, designers and engineers breathe life into the most extreme construction projects ever conceived. Follow some of the top bridge builders and engineers in the country as they try to tackle the biggest construction project in California history – the new Oakland Bay Bridge. Expected to be the most heavily trafficked bridge in the nation, this $2.8 billion monster will span the East Bay, connecting San Francisco and Oakland. The project was due to be finished in 2003. But now, it's looking more like 2007. While there's enormous pressure to stay on schedule, the daily, unexpected difficulties associated with building a two-mile, earthquake-proof road over 300 feet of water are tough to beat. |
