While no Metro stations will be closed this weekend, the Red, Orange and Green lines will be affected by track work.
On the Red Line, expect delays with trains running every 20 minutes from Glenmont to Shady Grove.
Additional trains will operate every 10 minutes in two segments: between Shady Grove and Farragut North, and between Glenmont and Judiciary Square.
Metro is advising its riders to use its Farragut Crossing service (which allows anyone with a SmartTrip card to walk between Farragut North and Farragut West free of charge) when transferring from the Red to the Orange or Blue lines.
It also suggests that anyone traveling to the Verizon Center this weekend should use the Judiciary Square stop instead of Gallery Place.
On the Orange Line, every other train will run only between Vienna and Stadium-Armory. Those trains will still run on regular 12-minute intervals, but longer waits can be expected at the following stations: Minnesota Avenue, Deanwood, Cheverly, Landover and New Carrolton.
On Sunday, trains will run every 20 minutes (as opposed to every 15 minutes).
On the Green Line, trains will run every 20 minutes.
While the Yellow Line will run on its normal weekend schedule, it will only operate between Huntington and Mount Vernon Square (rather than Fort Totten). Metro advises anyone traveling to or from Mount Vernon Square to use the Green Line.
The changes will be in effect from 10 p.m. Friday to closing time Sunday.
There is no scheduled work on the Blue Line, which will operate on a normal weekend schedule.
