St. Louis and Chicago travel
If you are driving from Chicago to St. Louis (or south on I-55 to somewhere beyond St. Louis) you may be interested in this time log from one of my drives between those cities. This was a weekday in March, I think.

4 hours and 50 minutes for driving from Chicago to St. Louis.
Allow at least 5 hours and 20 minutes so one can take a 30 minute break.
Add another 30 minutes of driving time if one leaves Chicago between 4:00 and 5:30. Add another 20 minutes (for St. Louis traffic) if one leaves Chicago between 11:00 and 12:30.
