From a WMATA press release:
Metro will conduct significant safety and reliability work on the Blue, Orange and Red lines to comply with National Transportation Safety Board recommendations during the Martin Luther King, Jr. (MLK) Holiday Weekend, causing some temporary service changes for customers. The agency will replace four track switches at the Foggy Bottom-GWU Metrorail station, conduct repairs on escalators and elevators and improve cell phone coverage.
On the Blue and Orange Lines, there will be no service between the Rosslyn and Farragut West Metrorail stations, and the Foggy Bottom-GWU Metrorail station will be closed during the MLK Holiday Weekend from 10 p.m., Friday, Jan. 14, to closing on Monday, Jan. 17. From 8 a.m. to 8 p.m., Jan. 15 to 17, extra Metro employees will be available at the Rosslyn, Foggy Bottom-GWU and Farragut West Metrorail stations to help customers navigate around the weekend closure. Virginia riders headed into the city are encouraged to use the Yellow Line to get downtown to avoid the track closure, yet still conveniently transfer to Blue and Orange trains at L’Enfant Plaza.
And on a side note, this is a head scratching advertising campaign considering you can’t drink on metro…
