I hate to be a nerd but...
When I got to the second sentence of the second paragraph in the quote, I had to read it over and over again to try and figure out what the author was trying to say. The word "than" just comes out of nowhere and it's like you're suddenly transported to a different sentence. I wondered how on earth someone who writes for Forbes could write this poorly so I clicked on the link...
The em-dashes are missing from your quote. One got turned into a comma and the other is just gone. You should stick those dashes back in there. I know it's not easy to make en-dashes or em-dashes outside of word processing software, so maybe just put a space before and after a hyphen - like I do. (A double hyphen is another option I notice a lot of people use.)
Sorry.

As for the topic at hand, I feel like the damage is already done in terms of ripping apart neighborhoods to make way for freeways. At this point, the transportation networks of most American cities are so dependent on those big freeways, that we're now stuck with them. Removing them would benefit the economies of certain neighborhoods but damage the economy of the greater region - and the latter would far outweigh the former.
Denver is currently putting a chunk of I-70 underground - a section that is currently all viaduct with a street that runs underneath it (it always reminds me of that Blues Brothers chase scene). It's hideous, imposing and divides the neighborhood in two. A section of the new highway will be capped with a park that IMO will help stitch the neighborhood back together. I suppose putting them (at least partially) underground could be considered a "solution," but man is it expensive.
This cheesy video does a good job of explaining CDOT's whole decision making process for why/how to do an expansion:
