Interstate 26 & U.S. 23

On August 5, 2003, Interstate 26 saw extension from the city of Asheville, North Carolina to the Tri-Cities region of northeastern Tennessee. The lengthening overtook U.S. 23 and friends from Asheville northward to Mars Hill, North Carolina. From there a new alignment travels west of existing U.S. 23 to the Tennessee state line at Sams Gap. U.S. 23 rejoins Interstate 26 to the north with both sharing pavement northward to Erwin. At Erwin U.S. 19W ties in for an overlap through Johnson City to U.S. 11E. The extension of Interstate 26 overtook the original Interstate 181 routing from U.S. 321 northward initially to Interstate 81. On August 5, 2005, the American Association of State Highway Transportation Officials (AASHTO) approved a second extension of Interstate 26 northward over the final nine mile segment of Interstate 181. This extends Interstate 26, 55 miles from the state line northward through Kingsport toward the Virginia state line.

The extension of Interstate 26 beyond Interstate 81 was sought by the city of Kingsport. An earlier proposal would have renumbered Interstate 181 into Interstate 126, but that was turned down in June of 2003. By March of 2007, all references to Interstate 181 were replaced in eastern Tennessee. The sign changes accompany a complete renumbering of the freeway interchanges to a mile based system starting at the western (northern) terminus. Since technically Interstate 26 travels east/west, milepost zero lies at the U.S. 11W interchange at Kingsport.

Interstate 26 scenes
Boones Creek Road (SR 354) east at the entrance ramp to Interstate 26 & U.S. 23 north at Exit 17. Rather than replacing the I-181 shield initially, TDOT added an I-26 shield. Several Interstate 181 shields south of I-81 remained posted through late August 2003. Photo taken 08/23/03.
Boones Creek Road west at the Interstate 26 & U.S. 23 southbound on-ramp. The original I-181 shield was simply replaced with an Interstate 26 shield. Since Interstate 181 was signed north-south, an East placard was added for then newly designated I-26. Photo taken 08/23/03.
