Build It Bigger - Season 4 Episode 7 الحلقة 7
The overhaul of the Bay Bridge is one of the biggest construction projects in the country right now. After almost a decade, California is nearing the crucial end of what has become its most expensive public works project ever, the $6 billion dollar rebuilding and earthquake-proofing of the Bay Bridge. This massive overhaul involves building an entirely new approach into San Francisco, retrofitting the 4.5-mile double suspension bridge with more than 17 million pounds of structural steel and completely replacing the 2.2-mile cantilever bridge with a self-anchored suspension bridge, a skyway, and new touchdown into Oakland.
