Interstate 26 Tennessee

Interstate 26 Tennessee
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 changed 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.
