| A modern above-ground fuel tank, with fenced enclosure, has been added at some point. Nearby ROW markers suggest that the ROW has been reused for fiber, now owned by Zayo. There are few indications of use at the Kingman site but you can hear ventilation equipment running down the vent shafts, suggesting that it's still maintained for the fiber equipment. | A modern above-ground fuel tank, with fenced enclosure, has been added at some point.

| + | An interesting detail of this site: it is connected via several one-pair aerial cables and a string of several poles to what appears to be an old open-wire route. Open-wire poles run for a short distance back towards Kingman before ending, wires hanging on the ground. A modern aerial cable was apparently also slung along these poles. There are indications (like an old unused messenger running between poles) that the exact way this was wired up had changed over time, but in any case, it seems that an old open-wire route to Kingman was reused to connect several telephone lines to the site. I have seen similar at other L-3I stations, I assume they were to provide a backup for service restoration work if the cable ever failed entirely... but another possibility is that this was installed after the L-3I was retired, for alarms on later fiber equipment. All of these cables are now cut where the open wire poles end. | ||
