The founder/publisher/editor-in-chief has this brief road-related outburst, BUT comes up with little to nothing as far as a real alternative. Instead of below-grading a-la US 75's redo north of downtown, he just says >poof< make it into a boulevard.
^ Typical new medievalist BS.
A lot of the area east of I-45 looks to be leaning industrial anyway.
I live in DFW and have not heard about that idea. The original editorial suggesting the removal of the elevated structure is dated 4-21-2010, and since I have not heard anything about it I think it is safe to say that the idea has not caught on and does not have any life in it.
It's a typical rant from anti-freeway interests, who claim that removing freeways will instantly cause revitalization. With the current funding climate for freeways, I'd say the chance of a freeway removal moving forward are zero. The east Dallas elevated will be here for a long time.
