Columns are still there, they haven't gone anywhere. The new stadium is inside the columns
Did they ever explain why they had to build the new stadium inside the columns? The old Soldier Field was the most beautiful stadium in all of football, and we just ruined it by making it look like a fish bowl. They could have expanded the stadium to seat more people than what they originally had by doing similar architectural adjustments that have been done to Michigan Stadium and Notre Dame Stadium over the years since old Soldier Field was designed in that fashion (at least I think it was designed that way).
