WMATA F1X Route Detours on Gorgas Road

WMATA's F1X bus route will detour around construction on Gorgas Road starting March 30, affecting southbound riders heading to Fort Belvoir Commissary. The detour runs through August 31 as crews work between Gunston Road and Woodlawn Road. Northbound buses toward King St-Old Town won't be affected by the construction.

Construction Zone Details

The construction project spans the section of Gorgas Road between Gunston Road and Woodlawn Road, requiring a five-month detour for southbound service. WMATA officials said the work necessitates rerouting buses to maintain safe operations through the construction zone. The agency coordinated with local authorities to establish the detour route that minimizes delays while keeping riders connected to Fort Belvoir Commissary. Northbound F1X service continues on its regular route without interruption.

Detour Route Specifications

Southbound F1X buses will exit their regular route at Gorgas Road, turning onto Gunston Road to bypass the construction area. The buses then resume their standard route on Sibert Road at Fort Belvoir Commissary, officials said. The detour adds minimal travel time for most riders, according to the transit agency. WMATA hasn't specified exact time impacts or whether additional buses will be deployed to maintain schedule reliability during the detour period.

Five-Month Timeline

The detour takes effect March 30, 2026, and continues through August 31, 2026, WMATA confirmed. Officials said the timeline aligns with the construction project's expected duration. The agency will monitor progress and adjust the detour end date if work finishes early or requires extension beyond the current August target.

Rider Information and Updates

F1X riders should expect the detour to remain in place for the full five-month period, with southbound trips following the Gunston Road route through late summer. WMATA encourages passengers to sign up for MetroAlerts to receive real-time service updates and any schedule changes during construction.
