I-94 was closed in both directions last night between Richardton and Hebron after a truck hauling 10,000 gallons of gas and diesel rolled in a median.
The accident happened around 9:30pm central.
Sergeant Shawn Skogen with the North Dakota Highway Patrol says no one was injured.
Skogen says the truck had about 9,000 gallons of gas and 1,000 gallons of diesel.
He says there was no damage to the tank but some fuel was dripping out of the top of a hatch.
Traffic was rerouted to Old Highway 10. Both lanes reopened shortly after midnight.
