Construction Forces Service Changes

The detour stems from ongoing construction at the P Street NW and 21st Street intersection, according to the transit agency. Officials classified the service disruption as high-severity, indicating riders should expect notable changes to regular travel patterns. The agency didn't provide details about the construction project's scope or which entity is performing the work. Transit agencies typically implement detours when street closures or utility work makes normal routing impossible, though the specific nature of this construction wasn't disclosed.

Riders Face Stop Relocations

Passengers who typically board or exit near P Street NW and 21st Street must use different stops along the detour route, officials said. The transit agency didn't release information about temporary stop locations or how far riders might need to walk to reach alternative boarding points. Officials also haven't said how many stops are affected by the closure. The agency recommended riders allow extra travel time and check for updated stop locations before their commute, though specific guidance on where to find that information wasn't provided beyond social media channels.

Transit officials said they'll restore normal service once the construction area reopens to bus traffic.
