Located only 2,000 feet south of the Missouri-Iowa border and less than 10 miles east of the Missouri-Nebraska border, Watson is the northwestern-most Long Lines site in Missouri. It’s also the only site that doesn’t have any paths to another site in Missouri.
Watson’s two microwave paths were southwest to Humboldt, Nebraska, and northeast to Red Oak Junction, Iowa.
The site is currently owned by American Tower Corporation. Its current purpose is unknown. In addition to a 294-foot, self-supported lattice tower, Watson consists of a base station akin to many that were expanded in the early 1960s for the TH-1 microwave radios. The same design can be found throughout north-central Illinois.
