F20 Detours Around Falls Church Construction
Westbound F20 buses detour April 18-27 due to Falls Church Drive construction closure
WMATA F20 Route Detours for Falls Church Work
Westbound F20 bus riders heading to Tysons will need to follow a detour route for nine days starting April 18 due to construction closing Falls Church Drive in the West Falls Church area. WMATA announced the temporary route change will affect westbound buses only, while eastbound service to King St-Old Town won't be impacted. The detour runs through April 27, transit officials said.
Construction Closes Street in West Falls Church
The street closure on Falls Church Drive necessitates the route modification for buses traveling toward Tysons, according to the transit agency. WMATA typically implements detours when construction projects block regular bus routes, rerouting service to nearby parallel streets while maintaining access to key destinations. The agency updated its service advisory on April 10, providing riders with advance notice of the upcoming changes. Officials said the construction work requires a complete street closure in the affected area.
Westbound Buses Follow Alternate Path
Westbound F20 buses will begin their detour at West Falls Church Station & Bus Bay E, then rejoin their regular route on Leesburg Pike at Haycock Road, transit officials said. The detour affects only the westbound direction toward Tysons, while eastbound buses traveling on Leesburg Pike to King St-Old Town will operate on their normal route without changes. Officials didn't specify the exact streets buses will use between the station and Haycock Road. The alternate routing will add travel time to westbound trips, though WMATA hasn't released estimates of how much longer journeys will take.
Nine-Day Detour Runs Through Late April
The detour takes effect Saturday, April 18, 2026, and continues through Monday, April 27, 2026, according to WMATA. The nine-day period covers two weekends and the weekdays between them. Officials said riders should plan for the detour throughout this period, though they didn't indicate whether construction might finish earlier or require an extension beyond the announced end date.
Riders Can Track Route Changes
F20 passengers should expect modified travel times on westbound trips during the detour period, particularly those boarding before West Falls Church Station. Eastbound riders won't experience route changes. Transit officials encouraged passengers to sign up for MetroAlerts for updates on the detour and any schedule adjustments. Moovit provides real-time bus locations and arrival predictions for F20 service, helping riders track buses following the temporary route.
