WASHINGTON — The roads and airports look to be jammed for Memorial Day weekend; if you’re staying in the area and hoping to get around on Metro, that may not be a bargain either.

Metro has announced that track work will affect service on all six lines from the 7 a.m. opening Saturday, May 28, through Monday, May 30.

The most dramatic change: There will be no Orange Line trains for the weekend. The Vienna, Dunn Loring and West Falls Church stations will also be closed.

The Silver Line is being adjusted to take over the eastern leg of the Orange Line: Silver Line trains will run from Wiehle-Reston East to New Carrollton.

Metro said buses will be available. A local bus will stop at all three closed stations and end at East Falls Church. Metro said will it take 12 to 15 minutes between each stop. An express bus will go from Vienna straight to East Falls Church, which Metro estimates will take about 25 minutes.

Other service changes:

The Red Line will single track between Fort Totten and Silver Spring;

The Silver and Blue lines will single track between McPherson Square and Smithsonian;

The Yellow Line’s northernmost stop will be Mt. Vernon Square; if you need to go farther than that, you need to take the Green Line;

And the Green Line will single track between U Street and Fort Totten.

On Memorial Day, Metro trains will run from 7 a.m. to midnight, and on a Sunday schedule; off-peak fares will be in effect all day, and parking at Metrorail facilities will be free.
