Metro on Monday morning announced its full schedule for maintenance this week and over the weekend. The weekend plans affect travel on all lines but the Green, but the biggest disruption will be on the Yellow Line.
Metro plans to work during the week on the Red, Blue and Green lines, but does not expect the work to cause delays.
Yellow Line: Work on the Yellow Line Bridge over the Potomac River will send Yellow Line trains on a different route: Huntington to Stadium-Armory stations via the Rosslyn tunnel from 10 p.m. Friday through the train system’s midnight closing Sunday
The Yellow Line trains will leave the terminals about every 20 minutes. The last train from Huntington on Friday, Saturday and Sunday nights will leave 15 minutes earlier than usual. Riders should add 20 minutes to their normal travel times because of the disruption.
Blue Line: From 10 p.m. Friday through closing on Sunday, trains will share a track between Stadium-Armory and Addison Road. Workers will be repairing the slabs underneath the rails.
Throughout the weekend, trains will leave the ends of the line about every 20 minutes. Add 20 minutes to normal travel times because of the disruption.
Orange Line: From 10 p.m. Friday through Sunday’s closing, trains will share a track between Vienna and West Falls Church. Workers will be replacing cross ties and insulators.
Trains will leave the ends of the line about every 20 minutes. Add 20 minutes to your regular travel time.
Red Line: From 10 p.m. Friday through Sunday’s closing, trains will share a track between Shady Grove and Twinbrook. Workers will be repairing rail and conducting other maintenance.
Trains also will share a track between Takoma and Forest Glen while crews work on station platforms. The trains will operate about every 24 minutes between Shady Grove and Glenmont.
Between 9 a.m. and 9 p.m. Saturday and Sunday, additional trains will operate on the interior part of the line, between Grosvenor and Fort Totten. In that zone, trains should arrive about about every 12 minutes.
Riders should add about 20 minutes to their regular travel times.
Here’s the plan for track work during off-peak hours. The transit authority doesn’t expect any delays, despite the sharing of tracks, because trains operate less frequently anyway during these hours.
Red Line: From 10 p.m. through the midnight closing Monday through Thursday, trains will share a track between Friendship Heights and Grosvenor. Crews will be working on the rails and on tunnel leak repairs.
From 10 a.m. through 2 p.m. Monday through Friday, trains will share a track between Shady Grove and Twinbrook. Crews will be working on the rails and cross ties.
Blue Line: From 10 p.m. through closing Tuesday through Thursday, trains will share a track between Stadium-Armory and Addison Road-Seat Pleasant. Crews will be working on the slabs under the tracks.
Green Line: From 10 p.m. through closing Monday, trains will share a track between Greenbelt and College Park while crews work on the rails. From 10 p.m. through closing Tuesday through Thursday, trains will share tracks between Mount Vernon Square and Georgia Avenue-Petworth. Workers will be preparing for a switch replacement.
In my Dr. Gridlock column Sunday, a rider asked about the pattern of Metro track work announcements. Metro has created a list that goes through June showing major track work, the sort that closes stations or requires diversions, such as this weekend’s work on the Yellow Line. On Mondays, Metro rounds out the list with other maintenance plans for the upcoming weekend and for the weekdays.
