For several months, the San Francisco / Oakland Bay Bridge has been in the midst of a major renovation and seismic upgrade.  The $7 billion dollar project has included building the world’s largest self-anchored suspension bridge, which was done without interrupting the daily traffic flow of more than 250,000 cars per day.  Now the project is finally winding to a close.

Several amazing construction feats took place during the course of the project, not the least of which was moving out a section of the bridge over a holiday weekend to allow a bypass to be installed so that construction could continue without closing the bridge.  See video of the bypass here.

The Bay Bridge is located in one of the most active earthquake regions in the world.  The new bridge is designed to withstand major quakes and is reported to have an expected lifetime of 150 years. Take a look inside the new Bay Bridge in this video at the Wired Gadget Lab and find complete details at the official Bay Bridge Info site:
