Its been called one of the deadliest wrecks in state history.  Twenty-five years ago twelve people lost their lives when a thick fog covered all lanes of I-75 near Calhoun, Tennessee. Forty-two people were injured.

The low visibility caused 99 vehicles to crash, and a few explosions.

Tennessee Highway Patrol Sgt. Steve Bearden was among the first to arrive on the scene.  He remembers the day quite well.  In his words:

"We had to just drive down the median.  There were cars and trucks on fire when I got there.  I'm grateful that some folks made it, but we saw too many who didn't.  

"Some of the vehicles were just crashed between trucks.  There was really nothing left.  They had to put them in dump trucks, and just haul them off."

"I pay tribute to the heroes who saved lives that day.  They don't talk about it much, but they put their lives on the line, dealing with all those vehicles on fire, and explosions all around them."

"I'm also thankful that the government has invested millions of dollars to install fog detectors, radar detectors, additional signage and personnel since then.  We have not had a similar tragedy since that day."

In worst-case scenarios, the highway has even been shut down during zero-visibility conditions.
