Commuters in the Washington, D.C. region should prepare for significant service disruptions this summer, as Washington Metropolitan Area Transit Authority (Metro) gears up for a major construction project along its busiest rail corridor.

From July 6 through Sept. 7, Red Line trains will not operate between the North Bethesda and Friendship Heights stations, temporarily taking three stations out of service while critical upgrades are completed.
The closure will impact the stations at Grosvenor-Strathmore, Medical Center and Bethesda, all of which will rely on replacement bus service during the two-month construction window.
To maintain connectivity, Metro plans to deploy frequent shuttle buses, including both local and express options. Riders will be able to use an express shuttle between North Bethesda and Friendship Heights, while a local shuttle will serve all affected stations along the route.
Despite the disruption, Metro officials say train service will continue on either side of the closure. Weekday trains will run every six minutes between Shady Grove and North Bethesda, and between Friendship Heights and Glenmont. Weekend service will operate at slightly reduced frequency, with trains arriving every eight minutes.
Shuttle buses are expected to run every five to eight minutes throughout operating hours, aiming to minimize delays for daily commuters.
The planned construction includes several major infrastructure upgrades designed to improve long-term service reliability and capacity across the Red Line.
Among the key improvements:
These upgrades are part of broader modernization efforts to accommodate growing ridership and improve connections across the region’s transit network.
While the temporary shutdown may cause inconvenience, the improvements are expected to deliver long-term benefits for passengers. The addition of a second mezzanine at Bethesda will play a crucial role in linking Metro rail with Maryland’s upcoming Purple Line, creating a more seamless transit experience.
Upgrades to station infrastructure, including lighting and platform repairs, are also aimed at enhancing safety and accessibility for riders.
Metro is encouraging riders to plan ahead, allow extra travel time and consider alternative routes during the construction period. With multiple transit options in place—including express and local shuttles—the agency aims to maintain service continuity despite the shutdown.
The Red Line is one of the system’s most heavily used corridors, and the summer construction schedule is intended to complete critical upgrades efficiently while minimizing long-term disruptions.
This project reflects a growing trend among major U.S. transit systems investing in aging infrastructure. As ridership rebounds and urban populations grow, agencies like WMATA are prioritizing upgrades that improve reliability, safety and multimodal connections.
The integration with the Purple Line, in particular, signals a shift toward more interconnected regional transit systems—an approach that could reshape commuting patterns across the Washington metropolitan area in the years ahead.
