An 80-year-old Morristown woman sustained serious injuries Wednesday afternoon in a one-vehicle crash on East Andrew Johnson Highway near the intersection with Larry Baker Road, authorities report.

This morning, Louise Ann Brown was in critical condition in a trauma intensive care unit at the University of Tennessee Medical Center in Knoxville, according to a hospital spokeswoman. First responders reported that Brown was unresponsive when they arrived at the crash site shortly after 3 p.m. She was airlifted to the hospital.

Just prior to the crash, Brown had picked up an 8-year-old child, a family member, from school. The child was not seriously injured.

Brown, who was driving 2014 Nissan Altima, was westbound on East Andrew Johnson Highway when she lost control of her vehicle around 3:06 p.m., according to officer Troy Rosenfels.

The car rolled off the left side of the roadway into a ditch before traveling off the right side of the roadway and colliding with a street sign. The vehicle then swerved back onto EAJ before traveling off the right side of the road a second time. The car rolled through a ditch before striking another street sign, according to the crash report.
