Downed power lines and repair work on them forced Durham County sheriff's deputies to close a section of Leesville Road early Wednesday morning.
The sheriff’s office said a tractor-trailer hit the lines about 3 a.m.
The road was closed from U.S. 70 to Doc Nichols Road.
Duke Energy reported that about 1,900 customers lost power because of the accident.
