Chain marker B2 215+00, on the Red Line of the Washington Metro, just north of Brookland-CUA station. This photo was taken on the first day that federal offices were open following the "Snowmageddon" snowstorm in early February 2010, and thus the chain marker sign is partly buried under a couple of feet of snow from two back-to-back snowstorms.
