Seasonal Driving Considerations
The Midwest corridor of this route is susceptible to rapid weather changes. Severe thunderstorms and tornadoes are a real threat from April through June, while winter brings heavy lake-effect snow, ice storms, and dangerously low wind chill. Flat terrain means high crosswinds can affect vehicle stability year-round, especially for taller vehicles. Spring flooding can also close highway underpasses and low-lying road segments.

Driving Strategy
A 471-mile drive from Mount Vernon to St. Louis takes a significant part of the day. Plan at least one fuel and rest stop along the way.

Starting early in the morning typically avoids afternoon storm development and rush-hour congestion near urban areas.
