Kingman L-3I Underground

Like other L-3I main stations, this is an underground, hardened station. There is no microwave tower at Kingman, and it has not received any of the additional underground buildings common at some other L-3I stations. There is just the surface entry structure (in its original white and blue paint), ventilation, and a hoistway.

Built AT&T, early 1960s?

Fate In use by Zayo fiber

During the L-3I era, Kingman functioned only as a power feed station.

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.

No license history per se for L-3I, but this segment was most likely abandoned along with the rest of the P-140 upgraded segment in the 1980s. Need to confirm this.
