Arlington County’s Board of Supervisors filed a lawsuit Thursday night seeking to block the U.S. Department of the Interior and the National Park Service from approving President Donald Trump’s proposed 250‑foot triumphal arch. The structure, modeled after Paris’s Arc de Triomphe, would be sited near Arlington National Cemetery, directly across the Potomac River from Washington, D.C.
Local safety and environmental concerns
The county argues the arch would sit within a busy traffic corridor and could cause “significant harm” to residents. Officials say the monument would likely require changes to nearby flight paths, increase noise and air pollution, and impede emergency transport routes. The suit also claims the National Park Service failed to conduct a thorough review of these impacts.
Federal aviation issues
The proposed location falls inside the main approach and departure corridors for Ronald Reagan National Airport. Federal Aviation Administration (FAA) officials have indicated that the arch must be marked with a flame and flood‑light projectors to ensure visibility for pilots. Some aviation experts have voiced safety concerns given the arch’s proximity to the airport’s flight paths.
The FAA previously dropped a requirement for red obstruction lights—normally mandated for structures over 200 feet near airports—citing the arch’s unique design. By contrast, the nearby 555‑foot Washington Monument retains standard lighting.
Broader Trump vision for the capital
The arch is part of President Trump’s larger effort to reshape Washington, D.C., which includes plans to renovate the Lincoln Memorial Reflecting Pool, redevelop a golf course in East Potomac Park, and add his name to the John F. Kennedy Center for the Performing Arts. Preservationists warn that these projects could alter several of the nation’s most historic landmarks.
Additional legal challenges
Three veterans and a military historian have also filed suit, arguing the arch would destroy the historic sightline between the Lincoln Memorial and Arlington National Cemetery. A federal judge in Washington last month ordered the Trump administration to provide 48 hours’ notice before any activity on the site, except for work to identify underground cultural artifacts.
President Trump recently said he intends to convert the arch into a military complex capable of deploying drones and positioning snipers, further heightening local concerns.
Responses
The White House and the Interior Department have not commented on the lawsuit.
