President Donald Trump's proposed 250-foot triumphal arch in Washington could win approval as soon as Thursday, November 5, 2026, when the National Capital Planning Commission meets to consider final approval. The arch is the only item on the agenda, and the online-only meeting is expected to take five hours because of the volume of public participation, NPR reported.
Virginia and the District of Columbia sued the National Park Service and the Department of the Interior to halt construction. Separately, a group of Vietnam War veterans has asked a federal judge to block the project, arguing it lacks congressional authorization and would disrupt the sightline between the Lincoln Memorial and Arlington National Cemetery.
U.S. District Judge Tanya Chutkan heard from two of the veterans on Friday and said she would move quickly to decide the case. She pressed Justice Department lawyer Robert Stander on sworn declarations from Defense Secretary Pete Hegseth and Homeland Security Secretary Markwayne Mullin, submitted on Wednesday, November 4, 2026, that claimed the project was necessary for national security. Chutkan said the justification had no detail or support. Asked whether additional details existed beyond the declarations, Stander replied, "There is not."
Final plans submitted to the planning commission make no mention of a military complex or a national security purpose, NPR reported. The commission approved preliminary site and building plans over the summer, and its chair, Mark Paoletta, expressed support for the arch in an op-ed published last month, according to NPR.
The administration says that after a successful commission vote, all that is needed to break ground is sign-off from its own Department of the Interior. The government notified a federal judge late last month that, pending those two approvals, "construction could commence as early as" Thursday.
Trump said from the Reflecting Pool on Monday, November 2, 2026, that the arch would be "one of the great things we've ever done." The White House has said the arch will "enhance the visitor experience at Arlington National Cemetery."
