I-26 End to End: States, Miles and Mile Markers

Measured state by state, I-26 runs 345 miles west to east from Kingsport, Tennessee to Charleston, South Carolina, crossing 3 states. Its longest stretch is 220 miles across South Carolina; its shortest is 54 miles in Tennessee.

State Miles Share Cities and mile markers
Tennessee 54 16% Kingsport 2 · Johnson City 22
North Carolina 71 21% Asheville 27
South Carolina 220 64% Greenville 25 (23 mi off) · Columbia 110 · Charleston 220

Mile markers count from each state's western line and start again at the next one, which is how most states number their exits as well. They are measured along the same road geometry these pages draw, so they land within a mile or two of the posted markers. A toll road that runs its own continuous numbering is the exception — on the New York Thruway the posts continue from New York City — and there the figure is how far into the state the place is rather than the number on the sign. Distances are measured state by state, never across a gap.
