Hello Aggies, I'm an Auburn alum coming to CS for the game and need traffic/parking advice

I'll be coming from your favorite city: Austin :). I've traveled the 290 route to CS plenty, but never on a gameday. Looking for info on parking and if there are any backroads or shortcuts. When can I arrive and get there before all heck breaks loose? Looks like game time is TBA. Where's the best place to park? Thanks in advance and hope it's a barn-burner.
