IntraCity Freeways, Mapped

Earlier today, I wrote this as an explanation filling in the gaps between highways ----> dead downtowns. Obviously, there is cause and effect, but few take the time to explain why:
You gut the integration, you lose the accommodation. Integration = demand. Accommodation = supply. Cause and effect. As I point out in mySpace Syntax of downtown Dallas post, the real estate market and building technologies built upwards at the exact same time as cities, states, and federal government unwittingly conspired to undermine the demand to fill those towers. But since the towers were new and shiny with whatever modern doo-dads a business may look for at the time, they cannibalized from historic buildings...which could then be torn down for parking all the residents that fled when their homes were taken for highways.
So I did a quick exercise examing inner loop highways in various cities, all at roughly the same scale. When given the time, I'll likely add in the railroads, which also have a divisive effect (see: "other side of the tracks") as well as a rough approximation of the land areas which remain relatively vibrant. It might be nice to test what the ratio of vibrant area vs overall land area within the loop might be and if there is any rough correlation.

Patrick,
I've heard a rumor the mayor is considering a plan to tear down the elevated portion of 75/I-45 between Woodall and I-30 to street level. Any truth to that?

I hope not because we havent finished our economic impact calcs yet before taking a finalized presetation to him. And frankly, I dont trust it in anybody else's hands after putting in a few hundred hours of my own tim working on the full white paper and presentation...which we're hoping to unveil within a month.

Thanks! Do you believe that I-30 and the mixmaster would have to be completed first before this would ever be considered? Also, who currently owns the land that portion of freeway resides on? City, State, Feds?

mostly because i don't know where else to post this, haha. Here's an interesting take on the city of algiers, and how Le Corbusier redesigned it (unsuccessfully).
