Metro has scheduled major track work, with the Red Line closed downtown, on a weekend filled with local festivals and events.

Only the Green Line will not be affected by this weekend's work schedule.

Beginning Friday at 10 p.m., no Red Line trains will be available at five stations in downtown D.C. -- Farragut North, Metro Center, Gallery Place, Judiciary Square and Union Station -- with trains stopping at Dupont Circle and starting again at the NoMa-Gallaudet U station. Buses will replace trains, but Metro warns riders to allow 30 minutes of additional travel time -- 50 minutes for riders heading to Farragut North, Judiciary Square or Union Station.

Meanwhile, Orange Line trains will share a single track between East Falls Church and West Falls Church and between Stadium-Armory and Cheverly, and Yellow Line trains will share a single track between Huntington and Braddock Road. Though no track work is scheduled for the Blue Line, riders should expect delays on those trains to accommodate the Yellow and Orange line work.

As a result, residents planning to attend one of this weekend's numerous events -- like the Silver Spring Jazz Festival, the Rosslyn Jazz Festival, the Alexandria King Street Art Festival, the DC Shorts Film Festival, the Takoma Park Folk Festival, the Adams Morgan Day Festival, the Nation's Triathlon and the Parks Half-Marathon -- will need to plan ahead to make sure they can get there on time.

Closing such a large portion of the Red Line means "a headache" for people like Wheaton resident Katonyah Haynie, who doesn't own a car and relies on the Red Line to get around.

"You gotta leave like three hours early," she said. "I need to get a car."

Capitol Hill resident Megan Sadler, who said she takes the Red Line every day, said taking the shuttles between stations "sounds like a disaster waiting to happen." She will opt for cabs instead, she said.

"Good thing the Redskins are away," said Frederick resident Leo Muldoon when he learned of the track work.

Though Metro spokesman Dan Stessel said he sympathizes with residents, he emphasized that the work is necessary almost every weekend.

"We're in the process of rebuilding the Metrorail system," he said. "This won't go on forever, but ... it is necessary work for where the system finds itself right now."
