​HISTORY - In the 1960's, a system of underground nuclear-hardened telephone booster stations was built to assure uninterrupted communications in the event of a nuclear attack. The average construction cost in 1960 was $4 million -- in today's dollars that is over $31 Million! The systems used copper bundle phone lines. When fiber-optics came into use,  these facilities became obsolete. At the time when they were closed in the mid 1990's, these stations were generally in fairly good condition. They are excellent investments and are easily re-purposed into data centers, homes, businesses and a variety of other creative uses.

GENERAL DESCRIPTION - AT&T Bunkers are large underground structures, ranging in size from 6,000 square feet to 55,000 square feet. Ceiling heights of 16' are common in these structures. Heavy blast doors, a decontamination shower, escape exits are part of the specifications. The bunkers were equipped with cooling and exhaust for dual electric generators; some have been scrapped and some yet remain on-site. Three-phase electrical service, an electric hoist, sump pumps, heaters, air conditioning, and dehumidification equipment is usually still functional.  Because they were designed with a live-in crew, elaborate air filtration systems, bathrooms, and sewage ejector pumps are typical and often quite functional. Tracts for these properties ranges from 5-15 acres, occasionally more. Some have high chain link fencing, paved parking, water wells, and 10,000 gallon stainless steel water storage tanks.
