If you're going after work then you'll be largely going against traffic to IAD and DCA. Not nearly as bad as trying to get from DC to BWI in the afternoon rush. For IAD, 95 and the outer loop of the DC Beltway should not be that bad (while it isn't my regular commute, the times I have driven it in the afternoon rush I did not get slowed down below the speed limit until around the "big curve" and that should be improved now). It used to back up for a few miles approaching the Dulles Toll Road/Access Road but they opened a 2nd lane on the exit ramp which has improved things greatly. Once you get on the Access Road the only traffic will be airport traffic.

DCA should be about the same as getting to IAD, maybe a few miles shorter. Instead of the Dulles Access Road you would go down the GW Parkway.

Even if you can go at the speed limit most of the way, it is still a long drive from northeast Baltimore. I'd guess about another hour or 1:15 longer than going to BWI.
