Hold your ears, a 100,000 motorcycles will be descending on D.C.'s streets on Sunday.
Organizers of Rolling Thunder, the event that draws attention to American troops missing in foreign wars, say that's how many riders will be joining them in demonstrations around the nation's capital on Sunday.
That means lots of road closures, as the convoys of riders make their way to the Vietnam Veterans Memorial at the National Mall.
The closures include Constitution Avenue, which will be shut from Pennsylvania Avenue NW to 23rd Street NW, and Independence Avenue from 1st Street SW to 23rd Street SW. Memorial Bridge and Memorial Avenue will also be closed from Route 110 to Arlington Memorial Circle. Ohio Drive will be closed from Independence Avenue to Virginia Avenue.
Officials recommend that those not participating in the ride to use public transportation. But riders should be aware there is some track work over this holiday weekend as well.
On the Blue and Orange lines, 4 stations will be closed starting at 10 p.m. Friday and continuing through Memorial Day. Capitol South, Eastern Market, Potomac Avenue and Stadium Armory are the stations affected. Metro is closing the stations so it can replace tracks and switches and improve underground cell phone reception.
Metro is suggesting riders add an extra 20-30 minutes to their travel time.
Free shuttle busses will be available between the four stations that are closed. Extra Metro staff will also be at those stations to help direct people to those busses.
