250-foot arch faces final federal vote Thursday

The National Capital Planning Commission will vote on Thursday to grant final approval for a 250-foot triumphal arch in Washington, D.C. The meeting is the last major administrative step before the Trump administration can break ground on the structure. The commission approved preliminary plans in the summer, and its chair, Mark Paoletta, has publicly supported the project. The administration claims that a positive vote will allow construction to start as early as the day of the meeting.

The arch would rise in Memorial Circle, a traffic circle on the bridge connecting the National Mall to Arlington National Cemetery. Renderings show a white concrete structure topped with three golden statues, including a winged woman holding a torch. The design is more than twice the height of the nearby Lincoln Memorial. Critics argue the structure would block important views and add risk to the complex airspace over the Potomac River. The Federal Aviation Administration issued a report in September stating the arch would not be a hazard if specific lighting rules were followed.

Legal challenges are already underway in federal court. A lawsuit filed by Vietnam War veterans and an architectural historian argues the arch is unlawful without explicit approval from Congress. The administration has not sought that approval, instead citing a century-old authorization for a pair of columns that were never built. District Judge Tanya Chutkan has consolidated this case with a new lawsuit filed by the governments of D.C. and Virginia. Those jurisdictions call the project flagrantly illegal and argue it violates federal environmental and historic preservation laws.

Judge Chutkan ordered the government to notify the court within one hour of any decision by the planning commission. The administration asked to extend that window to 24 hours, citing the time needed to draft official notices. The judge kept the one-hour timeline but clarified her wording. On Wednesday night, the government informed the court that Grunley Construction Company, a Maryland-based firm, may be arranging off-site preparations for construction. The firm is not necessarily mobilizing yet but is acting in anticipation of permit approval.

Public opposition to the arch has grown louder as the vote approaches. Nearly 120 citizens have signed up to speak at the online commission meeting, an unusually high number for such proceedings. More than 100,000 people have submitted written comments against the project. Democratic lawmakers and historic preservationists have joined the legal effort to stop the build. The White House has called the arch an enhancement of the visitor experience at Arlington National Cemetery and one of the most iconic landmarks in the world.

President Trump gave the project prominent airtime in his final in-person remarks before the midterm elections. Speaking from the Reflecting Pool on Monday, he called the arch one of the great things the country has ever done. He also announced that the structure would serve as a military complex housing snipers and ammunition. Defense Secretary Pete Hegseth described the project as a generational national defense opportunity in a court declaration. Judge Chutkan questioned how the government would square installing military equipment with accommodating up to 22,000 civilian visitors per day.

The planning commission is expected to greenlight the arch, but a ruling from Judge Chutkan could block construction. The judge has expressed skepticism about the government’s sense of urgency and its national security claims. The administration says construction will take two to three years, with crews working 20 hours a day. It argues that the first six months will involve underground excavation, making a judicial pause unnecessary. Lawyers for D.C. and Virginia countered that the government would suffer no harm if it had to wait before building what they consider an illegal monument.

The commission meeting is scheduled to adjourn at 6 p.m. ET. The first registered speaker is Michael Lemmon, a veteran and retired foreign service officer who is a plaintiff in the main lawsuit. Lemmon said he hopes to be buried in Arlington National Cemetery but not in the shadow of the arch. The government must notify the court immediately after the vote. The judge will then decide whether to issue a preliminary injunction to stop the project while the legal battle continues.
