If you’re not off on Monday, and you ride the Metro’s Green or Yellow Line, you probably want to read up on the shuttle service that will bridge the Yellow and Green line. There are specifically three shuttles:
Chinatown/Gallery Place to Anacostia with many stops
Chinatown/Gallery Place to Navy Yard, direct
Chinatown/Gallery Place to Anacostia, direct
Get ready for some serious Monday pandemonium, and weekend disruption. I’d just plan to work from home, if you can.
