That's not very long distance. Nor is it very high speed. Nor is it
terribly reliable, as directional antennas are sensitive to alignment
issues (and as range goes up, so does this problem.)
That's also part of the solution; shorter distances between towers mean
less alignment problems and much lower power requirements, and the
reduced marginal cost to add dishes and transceivers to the same tower
naturally lead to a finer mesh of wireless links.

improved, sure. But if it made sense, would T and MCI have turned
down all their existing (and fully depreciated!) MW backbone? I've
got my doubts. Remember, in the same time period installed fibre has
had its capacity increase by several orders of magnitude.
None of the MW links around here seem to have been taken down or out of
service, in fact new ones have been piggy backed on cell towers.
Meanwhile, unused rail is being taken up and right-of-ways reclaimed
when they would otherwise make wonderful fiberways.
