The San Francisco 49ers opened their new stadium last week, and while the result was not what we were hoping for, they did still kick off a fancy new stadium. The stadium took approximately 29 months to construct, and EarthCam was able to document the entire project. The video above features a time lapse of that entire time, leading up to the 49ers first game at the stadium. Don't turn your volume up too much as the sound with it is a little loud. But it's definitely worth watching.
