999 Private Road, Chicago

Reinforced underground bunker facility with rare defensive infrastructure and long-term operational potential. Originally constructed in 1965 as a hardened communications site, the primary structure includes 2-foot-thick steel-reinforced concrete walls, copper mesh shielding, and a spring-mounted floating floor system engineered to absorb blast or seismic impact. Designed to withstand a 3-megaton nuclear blast within a half-mile, this property was built for resilience and continuity. Located approximately two hours from Chicago, the property is privately held and discreetly situated, offering excellent regional connectivity for strategic operations, specialty storage, logistics, or secure asset protection. Improvements have been made over time, while maintaining the core blast-rated infrastructure. This is a rare opportunity for buyers seeking secure physical infrastructure outside standard commercial offerings. Exact location, architectural schematics, and interior details are withheld from public marketing. Full information package is available upon executed NDA and verified proof of funds. Do not approach site or disturb without prior written authorization.
