Highway system

Interstate 26 (I-26) is a main route of the Interstate Highway System in the Southeastern United States. Nominally east–west, as indicated by its even number, I-26 runs from the junction of US Route 11W (US 11W) and US 23 in Kingsport, Tennessee, generally southeastward to US 17 in Charleston, South Carolina.[2] The portion from Mars Hill, North Carolina, east (compass south) to I-240 in Asheville, North Carolina, has signs indicating FUTURE I-26, because the highway does not yet meet all of the Interstate Highway standards.

Northward from Kingsport, US 23 continues to Portsmouth, Ohio, as Corridor B of the Appalachian Development Highway System, and beyond to Columbus, Ohio, as Corridor C. In conjunction with the Columbus–Toledo corridor in Ohio formed by I-75, US 23, and State Route 15 (SR 15), I-26 forms part of a mostly high-speed four-or-more-lane highway from the Great Lakes to the Atlantic Coast at Charleston, South Carolina.
