The P20 normally connects Fort Totten and Greenbelt Metro stations in Prince George's County, Maryland.
Context

WMATA regularly accommodates Greenbelt's annual Labor Day Parade with service adjustments, officials said. The parade is a longstanding community tradition in the Prince George's County city. Officials didn't specify how many riders typically use the P20 on holiday Mondays or how many passengers the detour might affect.

The detour will affect the P20's normal route through Greenbelt, though officials haven't released specific street-by-street routing details or which stops will be temporarily relocated. WMATA classified the change as high-severity, indicating significant impact on regular service patterns. The agency said detailed detour routing information is available on its service status page. Specific start and end times for the detour weren't provided, though officials said the changes align with parade hours.
Timeline
The service change takes effect Monday, Sept. 1, 2025, for Labor Day. Officials announced the detour Aug. 31, giving riders about 24 hours' advance notice before the holiday weekend. WMATA didn't say when normal P20 service will resume, though temporary event detours typically last only a few hours. The agency said riders should check its website for real-time updates throughout the day.
Impact
