The two spots that trouble me are in Jackson, MS and in Shreveport. Knowing that, I just slow down. that means that 99% (a figure of speech, obviously) of I-20 is fine through Mississippi and Louisiana.
There is a good bypass around to the north in Shreveport. I think it better than going straight through.
Be aware of the bridge across Cross Lake on the bypass around Shreveport.  This bridge was built to prevent liquid spills getting into the lake since it is Shreveport's drinking water supply.  The normal grade of our highways being a bit lower on the outside reverses on this bridge.  The roadway is lower on the left side thus allowing any spilled liquids to run to the center where it enters a drain system that runs off the ends of the bridge to a retention pond.
What does this mean to us drivers?  Hold on to your steering wheel when you enter this bridge because your vehicle will want to turn left.  You will have to hold a little right pressure on the wheel all the way across.  It isn't a real hazard as long as you know it or aren't asleep at the switch when you enter the bridge.
