The only time I recall seeing a really major jam on I-24 south of Nashville was when there was a music event of some sort. We were going north but the southbound lanes were jammed for maybe 5 miles. It's just a roll of the die, you can stuck in a traffic jam in just about any major city. I've decided that most of the time you just waste more time trying to bypass a big city than you do in just driving thru.
The only exception is when the geography of the roads makes it possible to bypass a city on a good fast road and actually save some time. San Antonio can be bypassed with Texas 46 for example. But that's because the interstate makes a "V" at that point and you can cut across it.
