WMATA Route A58 Detours Around Rosslyn Tunnel Work

Riders on WMATA's route A58 will face detours through early July as construction closes the Central Place Tower Tunnel in Rosslyn. The Washington Metropolitan Area Transit Authority announced the temporary routing change, which takes effect March 1, 2026, and continues through July 3, 2026. Eastbound buses toward Farragut Square will detour via N Moore Street at Wilson Boulevard before resuming regular service on M Street, NW at 34th Street.

Construction Impacts Four-Month Period

The Central Place Tower Tunnel closure represents a significant infrastructure project affecting bus operations in the Rosslyn corridor. WMATA officials said the construction work requires complete tunnel closure during the four-month period. Route A58 Wilson Blvd-Farragut Sq serves as a key connection between Arlington County and downtown Washington, carrying commuters and residents through one of the region's busiest transit corridors. The agency updated its advisory on April 20, 2026, confirming the construction timeline and detour specifics.

Eastbound Service Rerouted, Westbound Unchanged

Only eastbound buses traveling toward Farragut Square will follow the detour route, according to WMATA. These buses will turn onto N Moore Street at Wilson Boulevard, then rejoin their regular path on M Street, NW at 34th Street. Westbound buses heading toward Seven Corners won't require any detour and will operate on their normal route throughout the construction period. The agency didn't specify how much additional travel time eastbound riders should expect, though officials advised passengers to allow extra time.

Detour Runs Through Summer Travel Season

The construction timeline spans from early March through early July 2026, covering spring and early summer months. WMATA officials said the work schedule requires the tunnel closure for the entire four-month period. The agency last updated its service advisory on April 20, 2026, at 3:40 PM, confirming the detour remains in effect through the scheduled July 3 completion date. Officials haven't said whether the project could extend beyond that date or if any weekend-specific changes might occur.

Riders Advised to Plan Extra Travel Time

Passengers should allow additional travel time during the construction period, WMATA officials said. The agency encouraged riders to avoid the area if possible and plan alternate routes for trips through Rosslyn. Riders can track real-time bus locations and receive service updates through Moovit, which provides current routing information for all WMATA bus lines including detour changes on route A58.
