I have heard it questioned on this board as to why the concrete walls on the existing North end of both sides of the stadium will remain after the expansion. Well, I did some digging and was able to find out that the answer to this question is an easy solution to a simple problem. The problem is that the existing East and West sides of the stadium are actually at different elevations. Thus, if the new expansion didn't have the two walls, there would either be a large step down on one of the sides, that could be dangerous, or, for comedy, one of the sections would be a tilted like a ramp. Thats all I know.
