There's no shortage of work being done on Metro Rail this weekend. Here's your guide on how to avoid any headaches getting around town.

WASHINGTON — The next 24/7 shutdown begins on the Green Line this weekend, as separate work shuts down part of the Red Line for a fourth straight weekend.

Green Line

On the Green Line, a two-week shutdown of Branch Avenue and Suitland begins this weekend and runs through Aug. 20.

Metro is running shuttle buses to and from Naylor Road.

While Naylor Road is open this weekend and all weekdays during this surge, the station will be closed the weekends of Aug. 12-13 and Aug. 19-20 as part of the work.

Find more on the work and your workarounds in the WTOP track work guide for this surge.

Red Line

On the Red Line, the fourth and final scheduled weekend of water sealant tests on just two of the many troubled stretches of tunnels means no trains through Bethesda.

Medical Center and Bethesda stations are closed, with shuttle buses connecting Friendship Heights to Grosvenor-Strathmore.

Due to the work, the last train is scheduled to leave Shady Grove at 11:45 p.m. on Saturday night, 40 minutes earlier than usual.

Other work

Yellow Line trains will not run north of Mt. Vernon Square this weekend, reducing service between Fort Totten and Mt. Vernon Square. Green Line trains will run in that area.

The Blue and Silver Lines are scheduled to single-track only after 10 p.m. Friday and Saturday between Stadium-Armory and Addison Road.
