WMATA Maintains C51 Service Through Construction
WMATA C51 bus route detoured through March 2026 due to Potomac Avenue construction
C51 Bus Detoured Through March 2026
Riders on WMATA's C51 bus route face altered service through next spring due to construction on Potomac Avenue. The detour began in August and will remain in place through March 2026, transit officials said. The agency classified the change as high severity, indicating significant modifications to the normal route pattern.
Construction Forces Extended Route Change
The Potomac Avenue construction project required the temporary route modification to maintain passenger safety and service continuity, according to WMATA. Transit agencies typically implement detours when roadwork blocks regular bus paths or creates unsafe conditions for passenger boarding. Officials didn't specify which portions of Potomac Avenue are under construction or what infrastructure improvements are being made. The seven-month detour period suggests substantial roadwork that can't accommodate regular bus operations.
Riders Should Expect Delays and Stop Changes
The detour affects regular stop locations along the C51 route, though WMATA hasn't released a detailed map showing exactly which stops are temporarily relocated or how far the detour extends from the original path. Officials said passengers should plan for potential delays during the construction period. The agency didn't provide specific information about how much additional travel time riders should expect. Transit officials said they're working to minimize service disruptions while maintaining safety standards during the extended construction timeline.
Detour Runs Through Winter and Early Spring
The route modification that started in August 2025 will continue through March 2026, spanning eight months of altered service. Officials haven't said whether the March 2026 end date could change based on construction progress or weather delays. WMATA typically reviews temporary detours periodically and adjusts timelines as needed, though the agency didn't indicate whether updates will be provided before the scheduled completion date.
Planning Tools Available for Affected Commuters
Regular C51 riders should allow extra travel time and verify current stop locations before their trips, officials said. The extended detour period means commuters will need to adjust their routines through the winter months. Moovit provides real-time bus locations and updated route information for WMATA services, helping riders navigate temporary service changes and plan trips with current detour routing.
