NASHVILLE, Tenn. (AP) -- A truck delivering a commercial explosive overturned north of Nashville, causing state troopers to close Interstate 65 in both directions for most of the day.
The interstate reopened around 6 p.m. eastern time.
Tennessee Emergency Management Agency spokesman Jeremy Heidt said the load of ammonium nitrate spilled when the truck rolled onto its top.
There was no indication of injury.
Heidt said the area was sealed off because if diesel fuel from the truck were to leak and mix with the load, there would be the potential for fire, although there would be no explosion because the blasting agent wasn't confined.
The incident occurred near the White House interchange, about 12 miles south of the Tennessee-Kentucky state line.
Traffic was diverted onto US 31-W around the crash site.
