Work originally scheduled for the Green Line was canceled, so weekend service will be normal on both the Green and Yellow lines. None of the other lines will be split for a major project, but there will be maintenance work resulting in schedule changes on the Red, Blue and Orange lines between 10 p.m. Friday and the midnight closing Sunday.

Red Line. Between Dupont Circle and Van Ness, crews will work on the third rail, repair tunnel leaks and fix catwalks. Between Rhode Island Avenue and Takoma, workers will install cable and fix the platforms.

Throughout the weekend, trains will leave the ends of the line every 20 minutes. From 9 a.m. to 9 p.m. Saturday and Sunday, more trains will be operating between Dupont Circle and NoMa. In that zone, trains should arrive every 10 minutes.

If you board the Red Line on its eastern side and would normally transfer to the Green or Yellow lines at Gallery Place, consider making the switch at Fort Totten. It might shorten your travel time. Keep this in mind if you’re going to Nationals Park for the weekend series with the Phillies.

Riders on the west side of the Red Line might prefer to take one of the buses along Connecticut or Wisconsin avenues, although I think that as long as you consult Metro’s Trip Planner for the Red Line schedule, the train usually will be a better option.

Orange Line. Crews will work on the platforms at Deanwood and Minnesota Avenue and perform track maintenance between Stadium-Armory and Cheverly. Trains will operate every 20 minutes all along the line.

Blue Line. Crews will work on the third rail and perform other track work that Metro says will result in smoother rides between the Van Dorn Street and King Street stations. All along the line, trains will operate every 20 minutes.
