Why Build a Utilidor?
Without the Tunnel
- Surface infrastructure vulnerable to weather, vandalism, and accidents
- Cooling losses over long surface pipe runs
- Extended downtime from utility failures
- Truck convoys for equipment transport across state lines
With the Utilidor
- Underground tunnel immune to surface disruptions
- Insulated chilled water loop with minimal thermal loss
- Redundant power distribution with 99.999% uptime target
- Electric vehicle track for secure, automated transport
Tunnel Alignment
The proposed 1-mile utilidor connects Colossus 2 in Whitehaven, Memphis TN to Colossus 2 South in Southaven, MS, crossing the Tennessee-Mississippi state line.
