Traffic started moving again on Interstate 24 near the Kentucky state line in Hopkinsville after two separate crashes caused massive delays.
Officials in Christian County said around 2 a.m. Saturday a tractor trailer carrying energy drinks caught on fire in Oak Grove.
Then, about an hour and half later, another wreck happened when a car crashed into another semi-truck and caught on fire.
A portion of the interstate was closed for more than five hours during the investigation.
It was not known if anyone was hurt in the crashes.
