The Trump administration could begin building a 250-foot triumphal arch in Washington on Nov. 5, the same day a federal planning commission is scheduled to review the design, according to a court filing by the Justice Department. The start would depend on approval from the National Capital Planning Commission, as well as same-day authorization from the Interior Department and National Park Service. The accelerated schedule would put construction in motion while lawsuits challenging the project are still pending. The proposed monument, sometimes called Independence Arch, would stand across the Potomac River from the Lincoln Memorial. Its design includes gold detailing and a 60-foot winged statue at the top. Vietnam veterans have sued to block construction, arguing the site is protected by federal law and that Congress must approve the project. The White House contends a 1925 congressional plan for two columns at the location gives the administration authority to proceed. A Virginia county has filed a separate suit, arguing the rushed process fails to meet environmental review requirements. The National Capital Planning Commission is expected to consider the design at its Nov. 5 meeting. Preservationists, historians and commission staff have raised questions about whether the structure would violate Washington’s height restrictions, threaten pedestrian safety, affect nearby monuments and worsen traffic on a busy thoroughfare. Charles Birnbaum, president and CEO of The Cultural Landscape Foundation, criticized the proposed timetable, saying the administration was moving ahead while bypassing required review and disregarding roughly 100,000 negative public comments. Administration officials have presented the arch as a tribute to the nation’s history. The dispute is part of a broader fight over Trump’s changes to Washington. Courts have also weighed challenges involving a planned White House ballroom and the removal of more than 400 trees at East Potomac Park for a possible golf course renovation. The outcome of the arch lawsuits could determine whether the administration can press ahead before courts resolve questions about its authority and the required reviews.
