You should expect delays if you are riding Metro this weekend.
The transit agency announced on Wednesday that crews will be repairing the tracks on four of the five lines in the rail system.
The Red Line will be affected between the DuPont Circle and Friendships Heights stations, where workers will replace circuits on the tracks. It will also be affected between the Takoma and Forest Glen stations so workers can install fiber optic cable and fix platforms.
Rail fastener improvements are scheduled on the Orange and Blue lines between the Smithsonian and Eastern Markets stations.
The repairs on the Green Line include rail maintenance between Georgia Ave-Petworth and Fort Totten and fastener renewal between Naylor Road and Branch Avenue. Yellow Line trains will run every 15 minutes to align schedule with Green Line trains.
Trains will single track between all the stations having maintenance done. The work begins at 10 p.m. Friday and wraps up Sunday night.
