The Arlington County Board in Virginia filed a lawsuit Thursday to halt construction of the Triumphal Arch planned for Memorial Circle, marking the first governmental legal challenge to President Donald Trump’s proposed monument. The lawsuit, filed in the Eastern District of Virginia, alleges the National Park Service is accelerating ground-disturbing construction without completing required environmental reviews under the National Environmental Policy Act (NEPA).
The county’s legal action argues the federal agency’s process has been rushed to align with the president’s directives, despite claims by the Park Service that no final decision has been made. Arlington County Board Chair Matt de Ferranti stated in a release that the project poses ‘severe, unique, and wide-ranging negative impacts’ to the county, which has participated in good faith in prior reviews. The lawsuit seeks to pause construction to ensure compliance with environmental laws.
Memorial Circle, located on federal parkland west of the Potomac River near the Memorial Bridge, sits adjacent to Arlington County. The county is represented by the legal advocacy group Democracy Forward. The White House and Interior Department did not immediately respond to requests for comment.
The lawsuit follows criticism from local officials and community groups over the project’s potential effects on traffic, environmental protections, and the site’s historical significance. Opponents have raised concerns about the monument’s placement and the adequacy of public input in the decision-making process.
The National Park Service has not publicly detailed the project’s current status beyond stating it remains in a review phase. The agency has previously indicated that any construction would require compliance with federal environmental laws, though the Arlington County lawsuit disputes the thoroughness of those efforts.
Arlington County’s legal challenge underscores ongoing tensions between local jurisdictions and federal agencies over land-use decisions that cross jurisdictional boundaries. The outcome of the lawsuit could set a precedent for how similar projects are reviewed in the future.
