WMATA F1X Route Detours on Gorgas Road Until August

Riders taking WMATA's F1X bus route toward Fort Belvoir Commissary will encounter a detour starting March 30 due to construction on Gorgas Road. The five-month detour affects only southbound buses, while northbound service to King St-Old Town continues on its regular route. Construction between Gunston Road and Woodlawn Road prompted the temporary routing change, which runs through August 31.

Construction Zone Details

The construction work spans a section of Gorgas Road between Gunston Road and Woodlawn Road in the Fort Belvoir area. WMATA announced the detour in late April, giving riders several weeks' notice before implementation. The agency said the extended timeline reflects the scope of roadwork needed in the construction zone. Officials didn't specify what type of construction is taking place or which entity is managing the project.

Detour Route Specifications

Southbound F1X buses heading to Fort Belvoir Commissary will turn onto Gunston Road when they reach the Gorgas Road construction zone. The buses will then rejoin their regular route at Sibert Road near Fort Belvoir Commissary. Northbound buses traveling toward King St-Old Town won't be affected and will continue using their standard route along Gorgas Road. WMATA said the detour adds minimal travel time for affected riders.

Five-Month Timeline

The detour takes effect March 30, 2026, and continues through August 31, 2026. WMATA's advisory notes the routing change remains in effect until further notice, suggesting the end date could shift based on construction progress. The agency typically reviews temporary detours monthly to determine whether adjustments are needed. Officials said they'll notify riders if the timeline changes.
