Freedom 250 Grand Prix Roadwork Is Underway: See The Map And What Southern Maryland Commuters Should Expect

WASHINGTON — Southern Maryland residents who commute into Washington each day are already beginning to feel the effects of the Freedom 250 Grand Prix, weeks before the first race car takes the green flag.

Crews have started transforming downtown streets into a temporary INDYCAR race circuit, with overnight construction, pavement upgrades and safety improvements now underway throughout the National Mall area. For thousands of commuters traveling from Calvert, Charles and St. Mary’s counties via Route 4, Route 5, Suitland Parkway or Interstate 295, the work marks the beginning of several weeks of changing traffic patterns ahead of race weekend.

The Freedom 250 Grand Prix, the first NTT INDYCAR SERIES race to be held through the streets of the nation’s capital, is scheduled for Aug. 22-23. The event will feature a 1.66-mile, seven-turn temporary street circuit winding through the ceremonial core of Washington, passing landmarks including the U.S. Capitol and the Washington Monument.

The event will feature racing, live entertainment, fan experiences and activities on the National Mall. General admission tickets were free, but the ticket request window closed June 7.

The disruption is not limited to race weekend.

Construction crews have begun bringing downtown streets up to the standards required for INDYCAR competition. That work includes resurfacing pavement, adjusting and leveling utility covers, repairing sections of roadway and preparing for the installation of temporary concrete barriers and protective catch fencing.

Much of the construction is taking place overnight between approximately 7 p.m. and 5 a.m. to reduce impacts on daytime traffic. Even so, commuters should expect intermittent lane closures, construction equipment and changing traffic patterns as work continues throughout August.

Once complete, the circuit will accommodate INDYCAR race cars capable of reaching speeds of more than 180 mph along portions of Pennsylvania Avenue.

What Southern Maryland Commuters Should Expect

The largest travel impacts are expected during race weekend, but transportation officials say drivers should begin planning alternate routes now.

The District Department of Transportation has not yet released its complete road-closure schedule. However, streets surrounding the National Mall, including portions of Pennsylvania Avenue, Constitution Avenue and Independence Avenue, are expected to face significant restrictions as the temporary circuit is assembled and later dismantled.

Anyone whose daily commute takes them through downtown Washington should allow extra travel time and monitor traffic updates as additional closures are announced.

Smithsonian, Federal Triangle and Archives-Navy Memorial-Penn Quarter stations are the closest Metrorail stops to the race circuit and are expected to experience heavier passenger volumes throughout race weekend.

Metrobus routes serving the area are also expected to be detoured. WMATA has a Major 2026 Bus Detour page that will include event information and plans to release additional service details as race weekend approaches.

Southern Maryland residents planning late-summer trips to Smithsonian museums, the National Mall, restaurants or other downtown attractions should expect changing traffic patterns throughout August as construction continues.

Whether you’re commuting through downtown Washington or planning a trip to the National Mall during race weekend, officials recommend checking event and transportation updates before heading out. Course maps, road closures, Metro service changes and other travel information continue to be updated as the event approaches.
