UPDATE: Roadway is back open.
Power lines are down across the highway near Pocasset due to a semi-truck hitting a power line, according to the Oklahoma Highway Patrol.
The north and southbound lanes of US-81 and 1240 were closed at about 3 p.m. this afternoon.
The Oklahoma Department of Transportation said those traveling through the area must use an alternate route as the utility company makes repairs.
This story will be updated when the road reopens.
