Devils Triangle (TN-116 Cumberland Mountains)

United States · TN-116 / TN-62

A notoriously rugged and unforgiving loop through the historic coal country of the Cumberland Plateau west of Oak Ridge. TN-116 circles past the towering stone walls of Historic Brushy Mountain State Penitentiary and climbs Fork Mountain. The road is marked by ultra-tight hairpins, active coal truck traffic, sudden pavement ripples, gravel wash from unpaved spur roads, and wooden guardrails bordering sheer drop-offs. Demands intense throttle control and aggressive countersteering; widely respected as Tennessee's grittiest mountain loop.
