The Arlington County Board has taken legal action to derail the construction of President Trump’s 250-foot triumphal arch, citing potential environmental and safety issues.

Described as a “vanity project” by the advocacy group Democracy Forward, the lawsuit seeks to prevent any demolition or construction until a thorough environmental review is completed. The board argues that the proposed arch would obstruct the symbolic view between the Lincoln Memorial and Arlington National Cemetery, a deliberate design choice to symbolise post-Civil War reunification.

In a statement, Matt de Ferranti, chair of the Arlington County Board, stated that the community has “the most to lose from this egregious and unlawful proposed project.” The lawsuit names Interior Secretary Doug Burgum, the National Park Service, and its acting director Jessica Bowron as defendants, accusing them of non-compliance with the National Environmental Policy Act and neglecting the potential negative impacts on emergency services and public safety.

The project, which has been in the works for over 125 years, was set to begin excavation in early September, according to a statement by Secretary Burgum. However, the groundbreaking has yet to occur, leading to ongoing legal challenges.

The lawsuit highlights specific concerns, such as the potential use of the arch for storing ammunition and serving as a staging point for drones and snipers, which the board believes could dramatically worsen public safety risks and accidents.
