F1X Bus 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 traveling to King St-Old Town won't be affected by the construction.

Construction Limits Access to Gorgas Road

The five-month construction project blocks regular F1X service on a section of Gorgas Road near Fort Belvoir, requiring route modifications for southbound trips. WMATA typically implements detours when road work prevents buses from accessing their normal paths. The agency said the changes ensure continued service to the Fort Belvoir area while construction crews complete their work. Officials didn't specify what type of construction is taking place or which entity is managing the project.

Southbound Buses Take Alternate Path

Southbound F1X buses will turn onto Gunston Road when they reach Gorgas Road, then rejoin their regular route at Sibert Road near Fort Belvoir Commissary. The detour adds distance to the southbound trip, though WMATA hasn't said how much additional travel time riders should expect. Northbound service continues unchanged, with buses maintaining their normal route through the construction zone to King St-Old Town. Officials said the directional difference stems from road access limitations during construction.

Detour Runs Through Late Summer

The route change takes effect March 30 and continues through August 31, WMATA said. The agency's announcement noted the detour will remain in effect until further notice, suggesting the end date could shift based on construction progress. WMATA typically provides advance notice before restoring normal routes after extended detours.

Riders Should Plan for Route Changes

Passengers using southbound F1X service should allow extra time for trips to Fort Belvoir Commissary during the detour period. WMATA encouraged riders to sign up for MetroAlerts to receive updates about the route change and any modifications to the timeline.
