I never drove through LA on the 23rd. But I always dread driving through LA. I always start my drive at around 10-11PM. By the time I get to LA, it’s 12-1AM. That give me the best chance of not hitting LA traffic. Also, if you have a 2nd person, I would recommend taking at least the 405, since it have carpool most of the way, except around UCLA area. If you’re a early riser, you can try do start your drive at 3AM instead and have an early sleep the night before.
