A Columbus road diet would be great, but the biggest issue with Grant Park is that its simply bisected by too many roads. It segments the park and makes it feel a lot smaller than it really is. Hard to get a respite from the city when you're never far from honking and exhaust fumes.

I'd be happy if they removed all roadways from the park, but that's probably not realistic from a traffic standpoint. LSD and Columbus would probably need to stay (reducing the lanes on Columbus wouldn't hurt). But between the three east-west streets (Monroe, Jackson and Balbo), at least two should be removed. It isn't necessary to have that many cross streets. Congress already gives access to Columbus from Michigan, keep one of the other 3 so that there can be a quick way to get to LSD without forcing all traffic on Roosevelt or Randolph. That would be more than enough. None of those streets gets all that much use east of Michigan anyway.

Eventually, any remaining surface road going through the park would ideally be put underground.
