DETROIT LAKES, Minn. - Highway 12 remains closed Wednesday morning between Murdock and DeGraff after an anhydrous ammonia tanker truck crashed with a train Tuesday morning.
The accident happened near the Koch Nitrogen Plant on Hwy. 12 just west of Murdock. The semi truck trailer was struck by the engine of the train pushing the tractor trailer off the road causing a rupture in the trailer and causing ammonia gas to leak from the trailer.
The Swift County Sheriff's Office says it could take up to four days before the clean up is done to ensure all personnel's safety.
The Koch plant will not be operational until the truck and trailer are removed.
Four people were transported to area hospitals for anhydrous ammonia inhalation.
The Sheriff's Office does not have an update on the condition of the truck driver, Eric Westin of Pine City.
Fire crews have been able to supply a water stream to the anhydrous ammonia vapor into aqua-ammonia.
Students from the Murdock Elementary School were moved to the high school while crews assessed the ammonia leak on Tuesday.
