A tractor trailer caught fire on Interstate 84 West in Tolland Saturday night.
The fire happened just before exit 68, crews said.
Fire crews have cleared the scene and state police remained on scene until the truck was towed.
Only the left lane of traffic was open while crews put out the fire.
The Department of Energy and Environmental Protection offloaded the remaining fuel in the truck, crews said.
It is unknown if there are any injuries.
