I live in Baltimore and go to school in College Park. To skip the tunnel, do as the others suggest and go west on 695 until you hit 95 again. Go south on 95. Make sure that you are in the 2nd lane to the right when you approach 495, as you need to make a left exit right after 95 splits in two. You'll then head toward Route 1 to College Park.
In my opinion, 95 is much faster than 295. 295 is only 2 lanes in some places, and it tends to get backed up periodically.
