A vehicle accident on I-75 in Loudon County late yesterday resulted in the driver transported to a trauma center. Trooper Brandon Webb says a 2017 Mercedes GLA operated by 23-year-old Holly Sanchez of Knoxville was traveling north at the 71 mile marker when she left the road, hit a culvert in the median and the vehicle rolled multiple times. Lifestar landed at the scene and Sanchez was flown to U.T. Medical Center for treatment. She was restrained at the time of the crash.
