Interstate 75 Fog Disaster

On the morning of December 11, 1990, an ordinary commute on Interstate 75 between Athens and Cleveland, Tennessee turned into a nightmare. As drivers crossed the Hiwassee River bridge, they were suddenly swallowed by a blinding wall of fog—so thick survivors said it felt like driving into milk. Within minutes, a single crash involving a tractor-trailer hauling hazardous chemicals triggered a massive chain reaction, leaving 99 vehicles mangled across the interstate as fires burned inside the haze.

In Episode 87, we unravel how this deadly fog formed, why no one saw it coming, and what first responders faced as crash after crash echoed through the mist. From haunting survivor accounts to the lawsuits that followed, this episode dives into one of Tennessee’s most chilling and lesser-known disasters—where visibility vanished, and lives were changed forever.
