St. Louis and Kansas City are not in the path of totality, and much of the best viewing is in rural areas.
The Transportation Department is urging motorists not to take pictures of the Eclipse while driving, and not to stop and park along interstate highways.
The state's Emergency Operations Center opened Friday in preparation for any eclipse-related problems, and state officials said cities have changed trash pick-up schedules and businesses have changed work schedules to accommodate expected traffic and visitors.
The totality of the eclipse -- when the sun is completely blocked -- will first occur in the St. Joseph area at 1:06 p.m.
Genevieve, a Mississippi River town about 96 kilometres south of St. Louis, will have 2 minutes and 40 seconds of darkness, and nearby Perryville 2:34.
