I like the spiral escalators.

We added the fast moving traffic in the 1950s. It resulted in the pedestrians going away.

I LOVE IT!!!!

While The Hindenburg Incident may have caused some reconsideration of the Airship Docks, I really like the two motor traffic levels (fast and slow). In fact, on many occasions in years past, driving south on Penn on my way home from Guthrie, I often wished there was a Super Overpass that would take the non-shopping motorist over the entire area--including the Turnpike--beginning at about 150th Street (33rd) and ending somewhere south of The Walmart Complex.

Perhaps the multi-level concept could still be adapted for Texting/Non-Texting in traffic.

I am particularly impressed at how the artist accurately prognosticated the shape of Cars of The Future.
And the car parking turntable in the garage.

If the Mesa Verde Cliff Dwellers had a vision like this, they would probably still be living there!
