It happened around 11 Sunday night near Millersburg Road when an ethanol truck caught fire.
Firefighters tell Eyewitness news the truck was heading to Nashville, TN when the fire broke out. Luckily the fire did not lead to an explosion.
Both north and southbound lanes of 164 were closed for most of the night while crews worked on putting the fire out and cleaning up the mess. Those lanes didn't reopen to traffic until around 6 Monday morning.
