Interstate 26 (I-26) is a nominally east-west (but physically more northwest-southeast diagonal) main route of the Interstate Highway System in the Southeastern United States. I-26 runs from the junction of U.S. Route 11W and U.S. Route 23 in Kingsport, Tennessee, generally southeastward 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, has signs indicating FUTURE I-26 because the highway does not yet meet all of the Interstate Highway standards. A short realignment as an improvement in the expressway was also planned in Asheville, but has been postponed indefinitely due to North Carolina's budget shortfalls. Northwards from Kingsport, US-23 continues north to Portsmouth, Ohio, as the Corridor B of the Appalachian Development Highway System, and beyond to Columbus, as the Corridor C. In conjunction with the Columbus-Toledo, Ohio corridor formed by Interstate 75, U.S. 23, and State Route 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. There are no plans for further official Interstate 26 extensions farther north than Northern Tennessee. ==Route description== |- |TN |31 |50 |- |NC |54 |86 |- |SC |221 |356 |- |Total |306 |492 |} I-26 is a diagonal Interstate Highway, which runs northwest/southeast. (Most of the other highway routes in this area are odd-numbered and run northeast/southwest.) The extension past Asheville is mostly north-south. Where I-26 crosses the French Broad River in Asheville at the Jeffrey Bowen Bridge (previously known as the Smoky Park Bridge), the highway runs in opposite directions from its designations. (I-26 West actually goes east. I-26 is concurrent with I-240, so that I-240 East and I-26 West are the same route.) 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 its numbers changed, although most of the road signs now indicate I-26 instead of I-240. I-26 has signs with an extra FUTURE sign above (and in the same style as) the EAST and WEST signs from Asheville north to Mars Hill, North Carolina, because the older U.S. Route 23 freeway does not yet meet all of the Interstate Highway standards. The road shoulders remain substandard or nonexistent along short sections of the route, and also, a rebuilding is planned in Asheville to avoid some tight interchanges. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Interstate 26」の詳細全文を読む スポンサード リンク
