It took $6.4 billion and 11-and-a-half years to build the new, hopefully earthquake-proof eastern span of the San Francisco-Oakland Bay Bridge. That's a lot of money and time, but now you can watch the last five years of construction happen in just four minutes.

As The Week notes, streaming video company EarthCam began capturing footage of the bridge's construction in 2008. The updated bridge opened yesterday, so EarthCam released their video, comprised of nearly 2 million images that capture 42,000 hours of construction.

This new span of the bridge replaces the earthquake-vulnerable span that partially collapsed in the 1989 Loma Prieta earthquake. The project has been under construction since January 2002.

I bet the locals wish it could have been finished in just four minutes. Or months. Or years.
