Both the Vienna and Dunn Loring-Merrifield Metro stops will be closed on Saturday and Sunday (Jan. 25-26) to let crews prepare for the Summer Platform Improvement Project, the website said.
The summer project will include the addition of slip-resistant tiles, updated LED lighting, charging ports and lit handrails.
This weekend, travelers can expect buses to replace trains between the Vienna and West Falls Church stops.
Besides those two stops, the Metro is scheduled to run trains every 12 to 15 minutes.
The Silver Line will not be affected by the work this weekend and will run on a normal schedule, according to WMATA.
