^^^^ I agree.
Underground should not be torn down.
Maybe the groundlevel (Underground) of Downtown can be re-energized with the completion of the new Atlanta Falcons stadium which is proposed to be situated on the groundlevel streets. The groundlevel streets are mainly used for parking and tailgating now. The proposed MMPT also utilizes the groundlevel streets and may even help re-energize the Underground area.
Atlanta should make a concerted effort to save as much historical structures as possible especially in that part of town. Underground is some of the most interesting history of Atlanta. Atlanta's railroad and transportation past should be celebrated more. Using hindsight, either the demolished Union Station and Terminal Station could have served as railroad museums. It's numbing to me that the Terminal Station was demolished for boxy dull RBR Federal Building (was there no other place to put that building other than where Terminal Station stood). I would hate to see something similar happen to Underground.
