Northbound lanes of U.S. Hwy. 59 in Tenaha have been closed for almost four hours after a frack mud truck overturned just before noon today.

The contents had to be uploaded to another tanker before the rig was uprighted. Emergency personnel and wrecker crews are clearing the scene now.

It's reported the driver of the rig was from Houston and turned the truck & trailer over in the northbound lanes when he was traveling in a curve. He was cited for failure to drive in a single lane.

DPS Corporal Jimmy Faulkner is investigating the incident.
