RAPID CITY

 

Rapid City is the main tandem office for the western part of South Dakota.  Originally a Northwestern Bell office, it was taken over by US West, and then Qwest.  The tandem was a Primary office with a direct connection to the Omaha Sectional Office.  This office was of importance during the cold war, as it was the connection to neighboring Ellsworth AFB, a strategic command base and was connected to Rapid City via cable and microwave.  Microwave also connected to Caputa.
