Arlington residents who take the Yellow Line to and from the District will have to take the Blue Line instead.
Metrorail service on the Yellow Line will be suspended from 10:00 p.m. Friday through system closing on Sunday, to allow the annual safety inspection of the Yellow Line bridge over the Potomac River.
Yellow Line riders in Virginia are instead advised to take the Blue Line, which will run at normal weekend intervals.
Orange Line riders, meanwhile, will be subject to delays this weekend. Orange Line trains will run every 20 minutes, starting Friday night at 10:00, due to track work and platform reconstruction at the Minnesota Avenue and Deanwood stations.
