The Arlington County Board filed a federal lawsuit Thursday against the Trump administration to halt the rapid construction of a proposed 250-foot triumphal arch near the nation’s capital. The action makes the Virginia governing body the first local authority to challenge the president’s monument in court, ABC News reported.
Filed in the U.S. District Court for the Eastern District of Virginia, the complaint targets the Department of the Interior, Interior Secretary Doug Burgum, and acting National Park Service Director Jessica Bowron, according to MS NOW. The county, partnered with the legal advocacy organization Democracy Forward, argued that federal agencies are circumventing mandatory environmental reviews to satisfy presidential directives.
The lawsuit claims the National Park Service is moving at an unjustified pace toward breaking ground at Memorial Circle, a traffic junction on federal parkland just across the Potomac River from Washington, D.C., and bordering Arlington. Local leaders maintain the administration conducted only a superficial assessment under the National Environmental Policy Act, disregarding local input.
“The Arlington County Board has filed this lawsuit because our community has the most to lose from this egregious and unlawful proposed project,” Arlington County Board Chair Matt de Ferranti said in a statement quoted by CNN. De Ferranti stated that county officials participated in good faith during the review process, only to see warnings about severe community impacts ignored.
Traffic disruptions and aviation hazards
Attorneys for the county warned that building the monument at Memorial Circle would create severe transit gridlock. The site serves as a vital corridor connecting Virginia and the District of Columbia for commuters, emergency vehicles, pedestrians, and cyclists, CNN reported. County officials specifically cautioned that congestion could impede emergency transport routes serving Arlington National Cemetery.
The legal filing also raised alarms regarding regional airspace. The 250-foot structure—designed to stand substantially taller than both the Lincoln Memorial and the Arc de Triomphe in Paris—sits directly within the main approach and departure paths for Reagan National Airport, according to news reports. The Federal Aviation Administration had issued a determination requiring the monument to feature a flame at its peak alongside floodlights, while waiving standard red obstruction lighting typically required on tall structures near airports, Al Jazeera reported.
Aviation groups have also expressed concern. Sara Nelson, president of the Association of Flight Attendants-CWA, said the monument introduces heightened risks that remain unaddressed following a January 2025 midair collision over the Potomac that killed 67 people, ABC News reported. The lawsuit also cited safety risks stemming from President Donald Trump’s stated desire to use the monument as a military facility capable of storing ammunition and hosting drones and snipers.
A broader battle over federal landmarks
The arch forms part of a larger initiative by the Trump administration to alter the architectural landscape of the capital region, including renovations to the Lincoln Memorial Reflecting Pool and alterations to the John F. Kennedy Center for the Performing Arts, according to the news reports.
While the U.S. Commission of Fine Arts granted initial approval for the arch, the project faces another ongoing legal challenge brought by three military veterans and an architectural historian in federal court in Washington, D.C. A judge in that case ordered the administration to provide 48 hours of advance notice prior to beginning any construction-related work, ABC News reported.
In response to the newly filed lawsuit, the Department of the Interior released a statement saying the agency “continues to follow all laws and regulations,” Al Jazeera reported. The White House did not respond to requests for comment.
The administration hopes to secure final approval for the arch during a National Capital Planning Commission meeting set for Nov. 5, CNN reported. The federal court has not yet scheduled initial hearings on the county’s complaint.
