A portion of I-81 was shut down early Thursday morning due to an overturned tractor-trailer.
Officials say the tractor-trailer was traveling north along I-81 near mile marker 12.5 in Guilford Township, Franklin County, when it crossed over into the southbound lane side swiping another vehicle.
The tractor-trailer overturned along an embankment, spilling a load of galvanized pipe onto the roadway.
Officials say the driver of the tractor-trailer is in serious condition. No other injuries were reported.
Police are not releasing the name of the driver at this time.
