Many central city Bell buildings were built with a "sugar scoop" deck
immediately below the roof for the old AT&T Long Lines dept. microwave
antenna pairs. This was before fiber. Typical hops were about 25 miles
in several directions from a major metro center to relays, and on
across the land to the next major metro centers. Many of the relays
still stand unused. AT&T did not dismantle the towers or antennas at
many of the relay stations. They sold them "as is" with the purchaser
responsible for the steel and obstruction. Look at a former Bell 
building in a downtown area of a major city and you'll see a flat,
overhanging roof with a setback vacant area in the story below.
Unlike the hinterlands, most of the antennas have been removed from 
these buildings.
