D40 Bus Detours on 7th Street Feb 14

WMATA's D40 bus route will detour around construction on 7th Street starting February 14, transit officials said. The temporary route change affects riders traveling through the DC-Maryland-Virginia metro area, though officials didn't specify which stops will be modified or how long the detour will last. The agency classified the service disruption as high severity, indicating riders should expect notable changes to regular travel patterns.

Construction Work Prompts Service Adjustment

The detour stems from ongoing construction work on 7th Street that requires temporary changes to bus operations, according to WMATA. Transit agencies typically implement detours when roadwork blocks regular routes or creates safety concerns for passengers and operators. Officials said the route modification will allow work crews to complete necessary improvements while maintaining bus service. Specific details about the construction project's scope and timeline weren't available by publication time.
