History
According to a January 29, 1954, article in The Advertiser Courier, the first major microwave route established through Missouri went live the following week (Feb. 1-5, 1954). Just a couple months earlier, the Jefferson City Post-Dispatch wrote Nov. 19, 1953, that the Holts Summit site was under construction and sites further west on the route (Elkhorn, Dover, Slater and Prairie Home) were completed, while sites at Hermann and Gray Summit still needed to be built. The sites roughly followed the present-day Interstate 70 corridor.
By 1960, six microwave routes existed throughout the state, not counting single-hop spur routes. The Kansas City-St. Louis route brought online in 1954 was still the main route for carrying telephone and television traffic across the state. Telephone-only routes existed between Dover and La Cygne, Kansas; and Elsberry and Campbell (extending southward into Arkansas.) Helena to Kansas City was a television-only route. Another telephone-only route was being constructed between Helena and Dover.
That hop had been completed by October 1966, extending the Dover-La Cygne, Kansas, route. Another major telephone/television route was established by that time, connecting Kansas City to Halifax, which continued the route to its terminal site in Oakdale, Illinois. A route extending from St. Louis to Hollister, following Interstate 44, was also established between 1960 and 1966. Planned routes that year included a telephone-only route from Slater to Kirksville, and a telephone/television route from Windsor to Walker, which continued westward to Fort Scott, Kansas.
