I've taken 301 accross the Harry Nice Bridge and up to rt 50 before. Didn't Like it at all. Way too much, very slow, stop and go traffic through Waldorf, etc. for me. I don't see the mixing bowl being too much of a problem since you're going against traffic. The Woodrow Wilson Bridge is another story. We would most likely spend a little time getting accross that. Then it would just depend on any "incidents" between there and the Bay Bridge. The fact that its a Thursday instead of Friday evening should help, regardless of route.
I know some shortcuts that could help on some of the jams.
