Interstate 26
Kingsport, TN to Charleston, SC
Interstate 26 connects the Tennessee mountains to the South Carolina coast, crossing the Appalachian ranges near Asheville, North Carolina before descending through the Piedmont to the Columbia basin and Low Country. The mountain sections through NC and TN involve sustained grades and winter weather, while the South Carolina sections are susceptible to ice storms that the state lacks equipment to treat adequately. Construction zone density near Asheville has been persistent. I-26 is a significant freight corridor connecting Tennessee and western North Carolina manufacturing to Charleston's major port.
