F1X Detours Around Gorgas Road Construction
F1X buses detour via Gunston Road from March 30 to August 31 due to Gorgas Road work
F1X Route Detours on Gorgas Rd Through August
WMATA's F1X bus route will detour around construction on Gorgas Road for five months, affecting southbound riders heading to Fort Belvoir. The detour takes effect March 30 and runs through August 31 as crews work on the road between Gunston Road and Woodlawn Road. Northbound buses toward King St-Old Town won't be affected by the construction.

Construction Zone Details
The road work on Gorgas Road will close a section of the route used by southbound F1X buses traveling from Alexandria to Fort Belvoir. WMATA typically implements detours when construction projects affect regular bus routes, particularly in areas serving military installations where alternative routing options are limited. The F1X provides express service between King St-Old Town Metro station and Fort Belvoir, serving commuters and military personnel. Officials said the five-month timeline reflects the scope of the Gorgas Road construction project.
Detour Route Specifications
Southbound F1X buses will turn onto Gunston Road at Gorgas Road instead of continuing on their regular route, WMATA said. The buses will then rejoin their normal path on Sibert Road at Fort Belvoir Commissary. Northbound service toward King St-Old Town will operate on the regular route without changes. Officials didn't specify whether the detour will add travel time to southbound trips, though riders should expect possible delays during the construction period.

Five-Month Construction Timeline
The detour begins March 30, 2026, and continues through August 31, 2026, according to WMATA. The agency said the construction timeline was set by the road work schedule on Gorgas Road. Officials haven't said whether the detour could be extended if construction runs longer than planned or if it might end earlier if work finishes ahead of schedule.
Rider Information and Updates
Fort Belvoir commuters and military personnel who rely on the F1X should plan for the altered southbound route through late summer. WMATA encouraged riders to sign up for MetroAlerts to receive service updates about the detour and any changes to the construction timeline. Moovit provides real-time bus tracking and detour information for WMATA routes, helping riders plan trips during construction-related service changes.
