Long Lines Site: Holts Summit, MO

The Long Lines site in Holts Summit, Missouri was part of the AT&T (Bell System) Long Lines network between the 1950s and 1980s. The Holts Summit site relayed telephone and television signals during that time, before being replaced with fiber optics.

The tower is situated on Greenway Drive in Holts Summit, and sits across from a newer neighborhood. The tower base station is somewhat hidden by a thick treeline which borders the road. Holts Summit itself is about five minutes away from the state capitol in Jefferson City, and is between Saint Louis and Kansas City. Therefore, this site would have endured somewhat heavy traffic.

The site was connected to Prairie Home to the northwest and Hermann to the east. According to the 1960 and 1966 Long Lines map, the station also had a television-only connection to the telephone Central Office in Jefferson City. According to a later 1979 map, the Jefferson City spur route was expanded to Eldon.

Oddly, the only network television station in the Jefferson City area — KRCG-TV — has always been located in New Bloomfield, which is located north-northeast of this site. Jefferson City is located to the southwest.

The tower is presently owned by Subcarrier Communications, who leases out tower space to cell phone carriers and other users. (Oddly, though, the site is not mentioned on Subcarrier’s website.) It is assumed that the tower is no longer operational, as AT&T has long sold the tower (likely in 1999) and the microwave radios turned down. This tower, like it’s neighboring site in Prairie Home, still has its top-most KS-15676 horns, as well as an additional cornucopia horn that would’ve likely served space-diversity purposes.

Similar to other Missouri sites, this station features the basic white concrete base building. This site would have been an un-manned, remote “repeater” site.

Over three years after first photographing/posting about this site, I revisited it to get a photo of the tower from a different angle. This photo comes out much better and reveals the space diversity antenna pointed toward Prairie Home still has its waveguide installed.

Photo of the Holts Summit, MO Long Lines tower, taken from the north. The KS-15676 horns on the left are pointed northeast toward Hermann, while the ones on the right are pointed northwest toward Prairie Home, along with the space diversity antenna. Note the space diversity antenna (Gabriel horn on right) still has the waveguide intact. Additional antennas would’ve been installed, pointed to the southwest toward Jefferson City.

The tower at Holts Summit. Notice the horns are still present on the tower and appear to be intact.
A closeup at those KS-15676 horns. The horns facing the camera (facing east) are going towards Hermann; the opposite side facing to the northwest to Prairie Home.
A sign reveals the true owner of this site. Subcarrier Communications leases tower space to cell carriers and other users.
The long gravel driveway leading to the base station.
The base station is similar to those found at other Missouri sites, including both neighboring sites (Prairie Home and Hermann) as well as Slater. The site was remote and un-manned. (Also note the odd duct-work configuration going to the roof-top HVAC unit.)
A locked door which separates the outside from inside the base station. Imagine walking through that door and discovering all of the TD-2 radios and the genset, as well as other equipment, still perfectly intact.
The old “death-star” AT&T logo that was used from the time when the Bell System was divested until the early 2000s. The death-star logo, believe it or not, was originally used on AT&T’s computer systems, such as the UNIX-PC. However, it became the corporate logo after courts forced AT&T to drop the bell logo.
A look up at the mighty tower which would’ve once been responsible for handling thousands and thousands of phone calls… at any given moment!
This particular base station, as well as the one in Hermann, appears to have been an older design that was extended at one point in time. These stations feature three sets of windows, instead of four that the Prairie Home and Slater stations appear to have. The Slater and Prairie Home stations appear to have never been extended or modified.
