(AP,WJLA) - A weekend of major construction work on all five lines of the Metrorail system is scheduled to start late Friday night, and some riders are being advised that their travel times may increased by an hour.
The biggest bottleneck expected from this weekend of work is expected to be on the eastern terminus of the Red line, where five stations - Takoma, Silver Spring, Forest Glen, Wheaton and Glenmont - will all be shut down starting at 10 p.m. Friday.
But that's not all. An inspection of the Potomac River bridge that ferries Yellow line trains between downtown Washington and Arlington coupled with a switch replacement at L'Enfant Plaza will cause Yellow line trains to operate via the Blue Line.
Trains on that line will run between Huntington and Eastern Market. There will be no Yellow line service between Archives and Fort Totten, either. Meanwhile, shuttle buses will replace trains between Archives and Waterfront on the Green line.
On the other side of the system, single-tracking will occur on the Orange line between East and West Falls Church and between Stadium-Armory and Cheverly. Finally, on the Blue line, trains will single track between Stadium-Armory and Addison Road.
Needless to say, it's a dizzying array of service changes and stoppages. You can find out even more about them here. Metro spokesman Dan Stessel attributes the avalanche of track work to the cancellation of construction earlier this year.
"Some of the work that was (canceled) when the Nationals were in the playoffs were rescheduled for this weekend," Stessel said. "You're seeing what was originally scheduled, plus a little bit more. That's why this weekend seems so intense."
The changes are confusing for locals and tourists alike, as maneuvering throughout the region on Metro will be much more complicated than usual.
"I'm probably going to do some homework on it tonight and make sure we can get where we need to go," Metro rider Janet Dupler said.
But for out-of-town visitors like Tammy Ruffalo, getting mixed up is a very real scenario.
"I'm counting on being able to look at the map and what the attractions and where I need to go...and just be able to do that," Ruffalo said. "I won't have the knowledge to work around a closure."
