WMATA Adjusts Routes for Arena Event Crowds
WMATA reroutes D40, D4X buses around Capital One Arena for Cardi B concert April 8
WMATA Reroutes D40, D4X Buses for Cardi B Show
Four WMATA bus routes will detour around Capital One Arena on Wednesday evening, April 8, as the venue hosts a Cardi B concert. The D40 and D4X routes along 7th Street and Georgia Avenue will reroute in both directions from 9:00pm until 11:59pm, transit officials said. The changes affect service between E Street and L Street northbound, and between K Street and Constitution Avenue southbound.

Concert Crowds Prompt Service Changes
The detours are necessary due to heavy vehicular and foot traffic expected from the special event, according to WMATA. Major concerts at Capital One Arena typically draw thousands of attendees to the downtown area, creating congestion on surrounding streets. Transit agencies routinely adjust bus routes during large events to maintain service reliability and avoid delays caused by road closures and crowd management. The arena, located in the heart of downtown Washington, regularly hosts concerts, sporting events, and other entertainment that impact nearby transit operations.
Four Routes Face Temporary Changes
Buses on the D40 7th St-Georgia Ave route will detour in both northbound and southbound directions during the three-hour window. The D4X 7th St-Georgia Ave Limited route will also detour in both directions. WMATA didn't specify the exact alternate streets buses will use during the detour period. The agency said riders can sign up for MetroAlerts for real-time service information, though specific details about stop relocations or service frequency adjustments weren't provided in the announcement.

Three-Hour Detour Window Wednesday Night
The detour takes effect at 9:00pm Wednesday, April 8, and continues until 11:59pm. WMATA typically implements event-related detours to coincide with peak arrival and departure times for arena events. Officials didn't say whether the detour timing accounts for post-concert traffic or if service will return to normal routes immediately at midnight.
Riders Should Plan Extra Travel Time
Passengers are advised to allow additional travel time during the detour period. WMATA recommends avoiding the area if possible. Riders who regularly use the D40 or D4X routes should expect longer trips and potential stop relocations along 7th Street near the arena.
