DC Metro D40, D4X Routes Face Saturday Detour

Riders on two DC bus routes will encounter detours Saturday, March 14, 2026, when construction closes part of Georgia Avenue NW. WMATA announced the temporary changes will affect southbound D40 and D4X buses from 5:00am to 5:00pm, though northbound service won't be impacted. The closure between Columbia Road and Harvard Street is necessary to accommodate construction work in the area.

Context

The single-day closure represents a typical weekend construction window that transit agencies use to minimize weekday commuter disruption. WMATA regularly coordinates with city construction projects to maintain service while allowing infrastructure improvements. Officials said the detour is designed to keep buses moving while work proceeds on the busy corridor. The agency didn't provide details about what specific construction work necessitates the closure.

Details

Southbound D40 buses will detour at Columbia Road and resume their regular route at Girard Street, WMATA confirmed. Southbound D4X buses will also detour at Columbia Road but won't return to their normal path until Howard Place. Northbound buses on both routes will operate without changes throughout the 12-hour construction period. Officials said riders should expect potential delays and consider alternative routes if their schedules allow flexibility.

Timeline

The detour takes effect at 5:00am Saturday, March 14, 2026, and will remain in place until 5:00pm that same day. WMATA typically restores normal service immediately after construction windows close, though officials didn't specify whether any cleanup work might extend beyond the scheduled timeframe. The single-day duration suggests the construction work is relatively limited in scope.

Impact

Passengers traveling southbound on the affected routes should plan for longer travel times and possible schedule changes during the construction period. WMATA encouraged riders to sign up for MetroAlerts to receive real-time service updates throughout the day.
