WASHINGTON (CBSDC) - Metro says its rebuilding efforts will continue over the weekend with scheduled track work, which means more delays!

Starting Friday and ending on Sunday, Aug. 19, Metro’s track work extends to the Red, Orange, Blue and Green lines.

On the Red Line, buses will replace trains between Silver Spring and NoMa-Gallaudet U stations to allow for tie and insulator renewal, structural work, platform reconstruction and fiber optic cable installation. Red Line trains will operate in two segments throughout the weekend:

– Between Glenmont and Silver Spring every 10 minutes during daytime hours and at regular weekend intervals at other times

- Between NoMa-Gallaudet U and Shady Grove every 10 minutes during daytime hours and at regular weekend intervals at other times

Free shuttle buses will replace trains between Silver Spring and NoMa-Gallaudet U stations. Three stations — Takoma, Brookland and Rhode Island Ave — will be closed. Fort Totten Station will be open for Green and Yellow line service only. Customers using shuttle bus service should allow 50 minutes of additional travel time. Customers traveling between Fort Totten and Downtown DC may wish to consider using Green or Yellow line service to avoid delays.

Orange Line trains will single track between Stadium-Armory and Cheverly stations to allow for platform reconstruction work. Throughout the weekend, Orange Line trains will operate every 20 minutes in each direction. Customers should allow about 10 minutes of additional travel time. View advisory

Blue Line trains will single track between Stadium-Armory and Addison Road stations to allow for repairs to the “floating concrete slabs” beneath the rails. Throughout the weekend, Blue Line trains will operate every 20 minutes in each direction. Customers should allow about 10 minutes of additional travel time. View advisory

Green Line trains will single track between College Park and Greenbelt stations to allow for track upgrades. Trains will operate at normal weekend intervals. However, every other train will begin/end service at College Park, rather than Greenbelt.  Only customers traveling to/from Greenbelt Station should allow up to 15 minutes of additional travel time.
