This east-bound black Cadillac didn't make the slight curve on Second Street about noon Wednesday, jumped the curb, clipped off a fire plug and plowed into an old oak tree.
The air-bag deployed and the driver was taken by ambulance to the Northwest Mississippi Regional Medical Center emergency room with non-life-threatening injuries.
Police kept traffic moving for about 30 minutes until the vehicle could be towed away.
Clarksdale Public Utility crews were on the scene within minutes to cap the plug and make repairs.
