The northbound lanes of I-81 in Schuylkill County are reduced to one lane due to a tractor trailer tanker rollover. The incident occurred around 6 a.m. at the 125.4 mile marker in Ryan Township. The driver of the rig was traveling north when he apparently lost control, entering the right berm and rolling the truck onto its side. It is believed the tanker is hauling a hazardous substance. The driver of the rig escaped injury.
