Your picture shows the turnstile end of the collusium. If you pay attention to your own picture, you'll see the gradstand in front. The collosium holds 96,000. The turnstile end is too far from the goal line, so the team has cut about 10,000 seats to allow fans a better view., But you probably knew that didn't you.

It is called the 'pier style' end of the coliseum because of the arches. They have turnstiles all around the coliseum.
