The Federal Aviation Administration (FAA) has approved President Donald Trump’s proposed 250-foot triumphal arch near Arlington National Cemetery, concluding it poses no aviation hazard to flights at nearby Reagan Washington National Airport.
The FAA’s decision, announced on Friday, requires the structure to include an eternal flame on top, a light beacon, and floodlight projectors to ensure visibility for pilots. The ruling removes a key regulatory obstacle for the monument, which Trump proposed to commemorate the nation’s 250th anniversary.
The arch, located in Memorial Circle between the Lincoln Memorial and Arlington Cemetery, will feature a gold-winged figure and two eagles, bringing its total height to 250 feet. The FAA determined the structure would have no substantial adverse effect on airport operations or navigation facilities. Construction must be reported to the FAA at least 10 days in advance.
Opposition and Concerns
Democratic lawmakers, including Sen. Tammy Duckworth (D-IL), have criticized the project, arguing it could complicate an already congested airspace where a fatal plane collision occurred in early 2025. Duckworth previously urged the FAA to reject the proposal, citing safety risks.
Veterans groups have also filed lawsuits to block the arch, claiming it would disrupt historic sightlines between the Lincoln Memorial and Arlington Cemetery.
Next Steps
The FAA’s determination is subject to review if a petition is filed by October 18. The agency had initially considered requiring red obstruction lights but later dropped that requirement.
The monument is part of Trump’s broader effort to redesign Washington’s monumental landscape, including plans for a new White House ballroom, renovations to the Lincoln Memorial Reflecting Pool, and redevelopment of a golf course in East Potomac Park.
