The facade completely circles the upper deck. This was taken during the pregame, they ringed the entire infield with Yankee Old-Timers.

You are now allowed to walk anywhere you want to, outside the seating areas, in the entire stadium. Field level, mezzanine, uppers, bleachers, everywhere. You can watch the game everywhere you go. No walls blocking the halls from the seats. Everywhere you stop to watch the game, there are a couple of HD screens nearby. Fantastic.
