For the second straight weekend, previously scheduled maintenance on the Metrorail Red and Yellow Lines will delay your commute through D.C. The disruptions, coupled with temperatures in the upper 90s across the area, might make things a bit challenging this weekend. Also keep min mind the 5K on Saturday night in Crystal City, as well as construction on the Baltimore-Washington Parkway.

Metrorail

The area will have two major disruptions affecting the Red and Yellow Lines.

Red Line: In the second of four straight weekend shutdowns through Bethesda, Metro will close the Medical Center and Bethesda stations for maintenance to prevent future water leaks. Buses will replace trains between Friendship Heights and Grosvenor from 7 a.m. Saturday through closing on Sunday.

Free shuttle buses will operate on two routes:

  • Local will operate between Grosvenor and Friendship Heights with intermediate stops at Medical Center and Bethesda. Add 10 minutes of travel time for each station stop.
  • Express will operate between Grosvenor and Friendship Heights only.

To allow for shuttle bus connections, here are the times for the final train departures:

Shady Grove:

  • Saturday 11:45 p.m., 40 minutes earlier than normal
  • Sunday 10:20 p.m., regular time

Glenmont:

  • Saturday 12:33 a.m.
  • Sunday 10:33 p.m.

Yellow Line: The bridge and tunnel between the Pentagon and L’Enfant Plaza stations will be closed for three straight weekends starting this weekend so crews can repair concrete holding up the tracks.

Passengers en route to D.C. will need to transfer to the Blue Line at Reagan National Airport and ride the clockwise loop into the city. Meanwhile, Yellow Line trains will operate at 12-15 minute intervals between Huntington and Reagan National Airport for grout pad renewal.

Blue and Silver Lines: The Blue and Silver Lines will be single-tracking Friday through Saturday from 10 p.m. until closing between Stadium-Armory and Addison Road stations while crews install cables to improve cell phone coverage.
