Looks like they are dropping $270M on the project. It also looks like they are only rebuilding the press box side of the stadium, plus other upgrades. I assume that they are going to leave room for a track for the 2018 Olympics.
Also lowering capacity from 90,000 to 77,000. The stadium now has a lot of bad seats and crowded walkways.
Still cool to think that this almost 100 years old stadium has hosted the Super Bowl, the World Series and two Olympics.
