The Redskins, Nationals, and D.C. United are all in action at home tonight, the first time in a couple of months that more than two of the District’s biggest major-league sides will be in action simultaneously. While that might be a dream for athletic enthusiasts, it will certainly cause some issues with Metro and traffic. Metro has assured that they will provide extra trains for the post-game crunch, but since all three matches will likely end between 9:30 and 10:30 p.m., that will be a delicate logistical task. (Of course, since FedEx Field and RFK Stadium are on the same path, that makes things a little bit easier.) A couple of reminders: if you are planning on driving to Morgan Boulevard or Largo Town Center and then walking and riding to the Redskins game, the parking fee is $25 — be sure you’ve got enough on your SmartTrip. Additionally, track work abounds this weekend — single-tracking between Eastern Market and Stadium-Armory on the Blue and Orange lines will (hopefully) be over by 5 p.m., but those connecting via the Red Line will want to add some additional travel time.
