In brief
The District of Columbia and the state of Virginia jointly filed a federal lawsuit Saturday demanding that President Donald Trump’s proposed triumphal arch on the Potomac River be halted. The plaintiffs argue the project would disrupt traffic, damage historic views, and pose environmental and security risks. A third lawsuit has already been filed against the arch design.
On Saturday, the District of Columbia and the state of Virginia filed a federal lawsuit aiming to stop President Donald Trump’s proposed triumphal arch on the Potomac River near Arlington National Cemetery. The lawsuit claims the structure would be unlawful and poses an “undue threat to traffic, historic views, and neighborhood residents.”
The complaint was signed by attorneys general Brian Schwalb of Washington, DC, and Jay Jones of Virginia and was filed in federal court Wednesday, October 27, 2026. It argues that the arch would create a traffic nightmare, impede emergency vehicle access, and diminish the visual integrity of a site of national importance.
In the lawsuit, the plaintiffs condemn the project as “flagrantly unlawful” and “legally indefensible.” They contend that the arch would bring massive environmental harm, disrupt commerce and that any ground‑breaking after the lawsuit would create a national‑security hazard, citing the government’s rapid schedule.
According to the White House, Trump’s arch would stand 76 metres (250 feet) high—30 metres taller than the Statue of Liberty—and would be a 12‑storey megastructure. Its design features a winged bronze statue of Lady Liberty holding an eternal flame, two mezzanines, and an observation deck with panoramic east‑west views, program spaces, offices and a “fire command centre.”
Veterans’ groups have voiced alarm that the arch would eclipse views of Arlington National Cemetery, a hallowed military graveyard. They warn that the structure could become a “military hub” with snipers and drone capabilities, heightening the sensitivity of the area.
White House officials said construction could begin as early as November 5, following the completion of a 106‑page proposal released last Friday. The proposal, which details the arch’s height, materials and program spaces, was meant to demonstrate compliance with federal and local regulations.
This lawsuit brings the total number of legal challenges against Trump’s arch design to three. Other lawsuits have been filed in state and federal courts across the country, each arguing that the project is a violation of historic preservation statutes and public‑interest obligations.
Attorney general Brian Schwalb has stated that “the court must keep this effort from escaping judicial scrutiny.” Jay Jones added that the arch’s footprint would reach “irreparable harm” to residents if construction proceeds without a court order.
If the court finds the plaintiffs’ claims credible, a preliminary injunction could block ground‑breaking and halt the arch’s construction until a full hearing can be held. The lawsuit also seeks an order to protect the Potomac corridor and preserve the historic views of the National Mall and the Smithsonian museums.
The federal court is expected to convene a hearing in early November to address the motion for preliminary relief. Until then, the Arch’s final design, funding sources and construction schedule remain unsettled, and local residents await the court’s decision on whether the project can move forward.
