A federal judge temporarily blocked construction of President Donald Trump's proposed 250-foot triumphal arch near Arlington National Cemetery on Thursday, November 5, 2026, hours after a federal planning commission approved the monument in an 8-4 vote.
U.S. District Judge Tanya Chutkan issued a 14-day restraining order stopping excavation, demolition, road closures and other work at Memorial Circle, where the administration had planned to begin construction immediately. Federal officials must submit a compliance report by November 9.
The ruling followed a lawsuit by Washington, D.C., and Virginia, which argued that the project lacked congressional authorization and would disrupt traffic, emergency services and surrounding communities.
In a 33-page opinion, Chutkan found that the two governments were likely to succeed in challenging the Interior Department's approval under the Commemorative Works Act, a federal law requiring congressional authorization and other approvals for memorials in the nation's capital.
The administration had relied on a 1925 law authorizing memorial structures associated with Arlington Memorial Bridge, arguing that Congress had already permitted the project. Chutkan rejected that interpretation at this preliminary stage, finding that the century-old statute did not appear to authorize the proposed arch or exempt it from modern federal requirements.
The judge also found that construction would impose immediate costs on both governments. Traffic disruptions could require additional personnel, road management and emergency planning, while environmental effects and excavation could create harm that would be difficult to reverse.
Earlier Thursday, the National Capital Planning Commission approved the monument after a hearing lasting more than nine hours. Supporters described the arch as a tribute to American history and military service, while veterans, preservation advocates and local officials raised concerns about its size, location and effect on nearby Arlington National Cemetery.
The structure would rise at Memorial Circle, near Reagan National Airport, as part of Trump's plans to commemorate the nation's 250th anniversary. The Interior Department issued its final construction approval the same day, allowing the administration to move toward work at the site.
Federal officials also argued that the arch could provide national security benefits, including surveillance and protection against potential attacks on the president. Chutkan found those claims unsupported by the project's earlier planning documents, noting that the security justification emerged only after litigation was underway.
The dispute had already reached federal court through a lawsuit filed by three Vietnam War veterans and an architectural historian challenging the monument's authorization and potential effects on the cemetery. Washington, D.C., and Virginia later brought a separate challenge seeking immediate intervention before construction began.
Chutkan consolidated the lawsuits and issued the restraining order shortly after the commission and the Interior Department approved the project. The federal approvals remain in place while the court considers the legal challenges.
The judge has postponed ruling on a separate request for a longer injunction that could extend the construction restrictions while litigation proceeds.
Federal officials must report their compliance to the court by Monday, November 9, as the 14-day construction halt remains in effect.
