CHIPLEY - After being a part of Chipley's skyline for more than six decades, the AT&T microwave tower is coming down. Work began earlier this week to remove the tower, which was part of the nation's technology heritage, thanks to AT&T making history in the late 1940s by launching the $40 million "microwave radio-relay skyway," a network of 107 microwave towers designed to transmit telephone and television signals nationwide. After three years of construction, the first call was made on the system in August 1951.

But just as microwaves replaced wires, fiber optics eventually replaced microwaves, and AT&T's giant towers became obsolete.
