If you’re traveling for the big game (or really, for any reason) this weekend, beware the Red Line in Maryland.

The Silver Spring, Forest Glen, Wheaton, and Glenmont stations will be closed as Metro works on integrating the stops onto the Purple Line, a forthcoming 16-mile light rail from the Maryland Department of Transportation. (When it’s done, the light rail will connect to the Red, Orange, and Green lines, as well as MARC, Amtrak, and Metro bus routes.) Shuttle buses will run between Fort Totten and Glenmont on two separate routes: one between Fort Totten, Silver Spring, Forest Glen, Wheaton, and Glenmont, and a separate shuttle will run between Takoma and Silver Spring.

Trains on the Green and Yellow lines will be running every 16 minutes and single tracking between the Mount Vernon Square and U Street stops for track circuit testing and switch replacement. The Orange, Blue, and Silver lines will be operating normally.

Here’s more from WMATA:
