Between Monday, Dec.18 and Saturday, Dec. 30, Metro will make critical Red Line safety repairs and other maintenance improvements. The work includes repairing a deteriorated concrete ceiling above both tracks which dates back to the earliest days of the Metro system. To complete the work safely and efficiently, Red Line service will be unavailable between Dupont Circle and Gallery Place.
