WMATA A58 Bus Detours in Rosslyn for Tunnel Work

WMATA's A58 bus route will detour around Rosslyn's Central Place Tower Tunnel for four months starting March 1, 2026. The Washington Metropolitan Area Transit Authority announced the temporary route change to accommodate construction work that'll close the tunnel through July 3, 2026. Eastbound buses traveling toward Farragut Square will take an alternate path through the area, while westbound service continues normally.

Construction Requires Tunnel Closure

The Central Place Tower Tunnel closure affects only the eastbound A58 Wilson Blvd-Farragut Sq route, according to WMATA. Transit officials said the construction work necessitates the four-month detour to ensure passenger safety and allow contractors access to the tunnel structure. The agency didn't provide details about the specific construction activities or project scope. WMATA typically coordinates major infrastructure work during periods that minimize rider impact, though officials haven't said whether ridership patterns influenced the March through July timeline.

Detour Route Details

Eastbound A58 buses will detour onto N Moore Street at Wilson Boulevard, then rejoin their regular route on M Street, NW at 34th Street, WMATA confirmed. The detour adds several blocks to the eastbound journey through Rosslyn before buses continue toward Farragut Square. Westbound buses traveling toward Seven Corners won't be affected and will maintain their normal route through the tunnel. Officials updated the service advisory on April 20, 2026, at 3:40 PM but didn't specify how much additional travel time riders should expect for the detoured eastbound trips.

Four-Month Timeline

The detour takes effect Sunday, March 1, 2026, and continues through Friday, July 3, 2026, according to WMATA. Transit officials said the construction timeline requires the full four-month closure period, though they didn't provide details about whether work might finish earlier. The agency advised passengers to allow additional travel time during the detour period and avoid the area if possible.

Rider Information

WMATA passengers using the A58 route should plan for longer eastbound trips through Rosslyn during the construction period. The agency provides service updates through its MetroAlerts system, though riders can also check real-time bus locations and route information through Moovit for current A58 schedules and any additional service changes. Officials said westbound riders won't experience route changes during the tunnel work.
