The latest confirmed development concerning the triumphal arch proposed by the Trump administration in Washington, D.C., is neither that construction has been finalized nor that a court has ordered it halted. Interior Secretary Doug Burgum said on September 3, 2026, that excavation work at the proposed arch site would begin within the next two weeks. The confirmed plan concerns excavation and testing at the proposed site, not completion of the arch’s entire construction.
Where is the triumphal arch planned, and how large will it be?
The triumphal arch is planned for Memorial Circle on Columbia Island in Washington, D.C., at the western end of the Arlington Memorial Bridge. According to official National Capital Planning Commission (NCPC) materials, its total height will be 250 feet, including the top of the statue. White House materials refer to the project as “Independence Arch” and link it to the 250th anniversary of the United States.
The NCPC approved the preliminary site and building plans submitted by the U.S. Department of the Interior. This does not mean that final construction approval has been granted. The NCPC has also issued comments requiring additional work before final review. The administrative process currently confirmed can therefore be summarized as preliminary plan approval, followed by further revisions and final review.
Has a court already blocked the work?
The related lawsuit is “Lemmon v. Trump.” Three Vietnam War veterans and an architectural historian filed the suit, arguing that a commemorative triumphal arch cannot be built without congressional authorization. After the administration announced its excavation plans, the plaintiffs applied to the court on September 4 for a temporary restraining order to block the work.
As of September 5, the lawsuit was still ongoing, and it had not been confirmed that the court had granted the request. The phrase “additional federal court setback” included in some searches may refer to the plaintiffs’ application rather than to a confirmed court order. What can be stated definitively at present is that the administration plans excavation within two weeks, the plaintiffs have applied for a temporary restraining order, and both final review and the outcome of the lawsuit remain undecided. The government was reported to be planning four test excavations after September 21, but those activities likewise do not mean that construction of the entire arch has begun or been completed.
