The Blue, Orange and Silver lines will run once every 20 minutes on each line between August 11 and August 26. This includes Rush Hour. Several stations in downtown DC will be closed the weekends of August 11 and 25, including Farrugut West, McPherson Square, and the Blue/Orange/Silver platforms at Metro Center (the Red Line platform at Metro Center will remain open).
Metro is doing this to repair the tightest curve in the system, between McPherson Square and Smithsonian Station.
