The Blue Line will be split into two sections this weekend due to track work between Pentagon and Rosslyn.
Metro is performing “NTSB-recommended track circuit replacement, fastener replacement and joint elimination,” according to the agency’s website. Buses will replaces trains between Pentagon and Rosslyn from about 10 p.m. Friday to system closing on Sunday.
Trains will run from Rosslyn to Largo Town Center at regular weekend intervals, Metro said. The other segment of the Blue Line — starting at Franconia-Springfield — will take the Yellow Line bridge over the Potomac to Mount Vernon Square.
Those using the free shuttle bus between Pentagon and Rosslyn should allow 20 minutes of additional travel time, Metro said.
