Federal documents filed to the Federal Register this week lay out the sheer scale of what it will take to build President Trump's proposed 250-foot triumphal arch at the gateway to Arlington National Cemetery, and the numbers are striking. The National Park Service is seeking a construction schedule of 20 hours a day, year-round, stretching two to three years.
That is not a typo. Two ten-hour shifts per day, every day, for up to three years, at one of the most hallowed sites in the country.
The arch, which the National Park Service says "is intended to celebrate 250 years of American independence," would rise from the center of Memorial Circle, directly adjacent to the entrance of Arlington National Cemetery and at the foot of Arlington Memorial Bridge. At 250 feet, it would stand roughly two and a half times taller than the Lincoln Memorial across the Potomac and approximately 30 feet taller than the monument at Plaza de la República in Mexico City, currently the largest arch in the world.
The National Park Service documents, reported by CBS News, describe a massive industrial undertaking in a space better known for quiet reverence. The construction site would demand "several tower cranes, forklifts, skid steers, drill rigs, and concrete pumping systems," the filings state.
The Park Service spelled out the work rhythm in plain language:
"Work would occur year-round, with work occurring in two 10-hour shifts per day (20 hours per day, year-round) for the duration of the construction period."
The documents also describe a "series of physical modifications within and around Memorial Circle" to accommodate the project. Westbound traffic on Arlington Memorial Bridge would be reduced from three lanes to two. Vehicle, bicycle, and pedestrian traffic in the area would all be affected.
The construction phase itself could last up to 11 months, though the broader timeline of two to three years encompasses the full scope of work. The Park Service is listed as the sponsor of the plan.
A structure of this size near Ronald Reagan National Airport naturally raises aviation questions. The Federal Aviation Administration said last week it is conducting a full aeronautical study in coordination with the National Park Service. An FAA feasibility study found the arch would "not penetrate the visual traffic pattern" and would not "have any effect on airport facilities or radio/visual navigational and landing aids."
The FAA added that "career safety experts found no adverse impacts to operations" at nearby Reagan National. The study did find that safety lights would need to be added to the structure.
For context, the proposed site sits on the Virginia side of the Potomac River but technically falls within District of Columbia boundaries. It occupies one of the most symbolically loaded pieces of ground in the capital, the crossroads where the Lincoln Memorial, Arlington Cemetery, and the Potomac converge.
President Trump has been promoting the arch plan for months. The 250-foot height is no accident. It mirrors the nation's 250th anniversary, which falls next year, the semiquincentennial of American independence. The National Park Service documents make that connection explicit.
At that height, the arch would tower over everything in its immediate surroundings. The Lincoln Memorial stands 99 feet. Renderings described in the federal filings show the Washington Monument visible in the distance, giving a sense of how the arch would reshape the capital's skyline from one of its most photographed vantage points.
Whether one views this as a fitting tribute to the republic's founding or an overreach into sacred ground depends largely on one's priors. But the federal government is clearly treating this as a serious, fast-tracked infrastructure project, not a concept sketch.
The comment period on the arch proposal is currently open and will close on June 15, 2026. That window gives the public, veterans' organizations, preservation groups, and local officials time to weigh in before the project moves further.
The open questions are real. No exact start date for construction has been announced. The specific federal officials driving the schedule have not been publicly named beyond the Park Service's role as sponsor. And the full scope of traffic disruption, on Arlington Memorial Bridge, Arlington Boulevard, and the roads bordering the cemetery, has not yet been detailed beyond the lane reduction already disclosed.
What is clear is the ambition. A 250-foot monument, built around the clock, at the doorstep of the nation's most honored burial ground, intended to mark a quarter-millennium of independence. The machinery is heavy. The timeline is long. The location is freighted with meaning.
Monuments are how nations tell themselves who they are. The Lincoln Memorial, the Washington Monument, the cemetery itself, each was controversial in its time, each is now woven into the fabric of the republic. The question is never whether a nation should build monuments. It is whether a particular monument, in a particular place, at a particular scale, earns the ground it stands on.
The federal filings make one thing plain: this is no longer a talking point. Tower cranes, drill rigs, 20-hour work days, years of construction, the government is planning to build. The public comment period is the moment for Americans to decide whether this arch belongs where the administration wants to put it.
A nation that can't agree on what to honor will struggle to agree on much else. But at least the process is in the open, filed, published, and available for every citizen to read and respond to before the first crane goes up.
