Interstate 26 (abbreviated I-26) is an east-west main route of the Interstate Highway System in the Southeastern United States. It runs from the junction of U.S. Route 11W and U.S. Route 23 in Kingsport, Tennessee, generally south and southeast to U.S. Route 17 in Charleston, South Carolina. The portion from Mars Hill, North Carolina, east (compass south) to Interstate 240 in Asheville, North Carolina, is signed as Future I-26 because it does not yet meet Interstate standards; a short realignment is also planned in Asheville.

Prior to August 5, 2003, the western terminus was at Interstate 40 and Interstate 240 southwest of Asheville. At that time, the final section of freeway in North Carolina, from Mars Hill north to the Tennessee state line, replaced the old two-lane U.S. Route 23. I-26 was extended into Tennessee on the US 23 freeway, taking over approximately half of the former Interstate 181 from U.S. Route 321/State Route 67 in Johnson City, Tennessee, to Interstate 81 south of Kingsport, Tennessee. The American Association of State Highway and Transportation Officials denied an extension of I-26 along the remainder of I-181 to Kingsport, since it would give a main interstate route a stub end (not connecting to another interstate). The extension was finally achieved by the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users, signed into law August 10, 2005. Thus I-26 now ends about two miles (3 km) south of the Virginia state line, and the freeway continues to the state line as US 23.

North of Kingsport, US 23 continues north to Portsmouth, Ohio, as Corridor B of the Appalachian Development Highway System, and beyond to Columbus, as Corridor C. In conjunction with the Columbus-Toledo corridor formed by US 23, State Route 15 and Interstate 75, I-26 forms part of a mostly high-speed four-lane highway from the Great Lakes to the Southeast. There are no plans for further I-26 extensions into Virginia, Kentucky and farther north.

  • Interstate 126 is a spur into Columbia, South Carolina from the northwest.
  • Interstate 326 was a temporary unsigned designation for part of what is now Interstate 77 south of Columbia.
  • Interstate 526 is a partial beltway of Charleston, South Carolina, running from U.S. Route 17 west of the city north to I-26 and back east and south to US 17 east of Charleston.

[edit] Notes

I-26 is a diagonal interstate, running northwest-southeast; most other routes in the area are odd numbers running northeast-southwest. The extension past Asheville is mainly north-south. When the extension was made in 2003, the exit numbers in North Carolina were increased by 31 to reflect the new mileage. The part that it shares with I-240 has not had the numbers changed yet, although most signs now indicate I-26 instead of I-240.

I-26 is signed with an extra FUTURE sign above (and in the same style as) the EAST and WEST signs from Asheville north to Mars Hill, because the older U.S. Route 23 freeway does not meet interstate standards. Shoulders remain substandard or nonexistent along short sections of the route, and a realignment is planned in Asheville to bypass some tight interchanges.

Exit numbers in Tennessee were formerly numbered backwards, increasing from east to west, because the road was formerly U.S. Route 23 and Interstate 181, two north-south roads. This exit numbering was flip-flopped to the correct way in March 2007 when exit numbers were changed on all 284 signs along the I-26 route; the remaining I-181 signs north of I-81 were also replaced by I-26 signs at that time. The old exit numbers will be displayed on signs with the new ones until March 2009.
