Today, the Cubs posted on their website drawings of what the planned bleacher expansion and Hall of Fame/museum buildings will look like.
These are nearly identical to renderings that they posted in 2001, when these projects were first proposed. The only difference can be seen in the drawings that show the back of the bleachers; the original ones showed support columns on the sidewalks. Those have been eliminated in the just-reached agreement, and the new drawings show the narrower sidewalks and new back walls.
Note that these are NOT detailed architectural plans, simply "renderings" that show what the project MIGHT look like when it is finished. I therefore reserve final judgment until I see more detailed information.
