A Cold War bunker in Utah

After WWII and with the advent of the Cold War with the Soviet Union, the US government helped to finance a continuity of communication plan which resulted in the AT&T L-Carrier Cable and Long Lines Network

Specifically built to be a repeating network of specialized coaxial cables that were insulated and hardened to protect against nuclear attack, as well as routed in such a way to avoid being near potential targets to continue communication services after the event of a nuclear attack. 

A picture of the full network at the time. Pic taken from here.

So, as pointed out in the map above, this system was created by Ma Bell (now AT&T) and in each major repeating hub there is a control center for them with a hardened bunker. The bunkers are meant to protect from radiation and will have enough supplies to last the staff 30 days of continuous operation after a catastrophic event. They also will usually house support equipment to help rapidly repair or replace local microwave tower equipment.

Specifically, the one located in Brigham City is an interesting one, as it is a particularly large facility and is equipped with blast detectors, and has a significant underground complex, which is not standard across all locations. What's even more interesting is that it still appears to be in use by AT&T, when it seems a majority of the sites have either been sold off or abandoned. 

Because it's still in use, there's not a lot of info on the interior of it, but because of several other similar sites have been bought by the public, we can at least see inside of those ones for a better understanding of what may be there. 

Here's another blog's great post on the inside of one in NY

The Drive's War Zone has an article on one in Scott City, Kansas

Enjoy, and don't forget to check the sites I sourced the pics from for more info on the whole project and national network.
