And if anyone is going this weekend -- If you're driving up from South of the District, AVOID Northbound NEW YORK AVENUE . There is a major construction project going on at the railroad bridges near union station. Going through the District on 395/SE Freeway will add a half hour to 45 minutes to your trip. I was up there the day the project started and it was a mess.
Approach the District using I 295 or Rt. 50 and come in from the North. I exited that direction to get home and the backups weren't as bad...You mileage may vary, though...It's D.C. traffic after all.
