But with 90 percent of the world’s subsurface office space—and 45 million additional square feet available for future occupancy in SubTropolis alone—Kansas City is in the vanguard, chipping away at the energy problem one chunk of limestone at a time.

I knew we had the most but I didn't know it was 90%. Springfield has a pretty good size one also.

also, at 40 feet wide (pillar width) you have 118 miles of excavated space. New York's light rail has 226 miles of routes. See where i'm going.

The Sunday version of The Today Show does a segment on Subtropolis. Over 6 million square feet of space leased to 55 companies with 1700 people working underground.

To put this in context, One Kansas City Place, at 42 stories, has 866,660 sq ft of space. The Town Pavilion complex has 1,200,000 sq ft of space, which includes the Boley Building and the Harzfeld's building. The Town Pavilion tower is 38 stories. The 18 story Richard Bolling Federal Building has 1.2 million square feet.

Another very large underground industrial space is the Carefree Industrial Park, a 4.2 million-square-foot subsurface development at 1600 N. Missouri Highway 291.
