Eastbound Highway 36 was shut down due to an accident around 6:30 Monday morning as two semis collided. William Smith, 32, was slowing to make a right turn at Route DD in Marion County when he was rear-ended by Raymond Nanneman, 59, of Salisbury. Nanneman’s trailer disconnected and came to rest blocking both lanes of eastbound traffic. He was transported to Hannibal Regional Hospital with moderate injuries.
