Metro is warning riders to expect up to 40 minute delays on the Blue and Orange lines this weekend as crews replace old track components, including a switch at the Rosslyn Metro Station.
The track work, which is also taking place on the Green and Red lines, comes on a weekend when Nationals, Capitals and DC United games are scheduled in the District.
Trains will begin single-tracking at 10:00 tonight. The work is expected to conclude at midnight Sunday.
