[HamWAN PSDR] Map of AT&T Wash. Microwave Network - 1976

[Randy Neals]

Solid lines are microwave.
Beaded lines are coaxial cable
Dashed lines are copper. Usually screened pairs.

Railways became routes for fiber in the competitive telco boom. Usually
cable was placed along roads and occasionally along private right of way.
