KINGSPORT — For the second time in three weeks, a black bear has wandered onto an interstate in Sullivan County and been fatally hit by a vehicle. Wednesday morning's collision occurred in the southbound lanes of Interstate 81 at mile marker 55. A Tweet from the Tennessee Highway Patrol's Fall Branch district included a pair of troopers at the scene with the bear's body. The caption also reminded drivers, "When you're involved in a crash, regardless if it’s with wildlife, please report the crash to authorities." On May 30, the THP reported a bear being hit and killed by an I-26 motorist.
