The National Park Service now plans to build Donald Trump’s proposed Triumphal Arch in Washington with work running 20 hours a day, two 10-hour shifts, for as long as two to three years. The planning documents released last week lay out a seven-phase project that would turn the monument into a long, heavy construction site near Ronald Reagan Washington National Airport.
The scale is what makes the project hard to ignore. The current designs call for a 250-foot arch built from concrete and clad in U.S.-sourced granite, with multiple cranes reaching up to 320 feet, along with concrete pumps, forklifts, skid steers and other heavy equipment. The release of the designs, renderings and reports is why the search interest has shifted now: the public is being asked to weigh in on a monument that is no longer a sketch but a detailed, years-long build plan.
The National Park Service report said the size was tied to the purpose of the monument, which is meant to mark 250 years of American independence. In one passage, the agency said smaller heights were not considered representative of that milestone, unlike the 250-foot arch proposed in the undertaking. The plan also says the first five months after excavation would be spent driving the foundation system about 75 feet down to bedrock, a process that would require about 30 trucks moving 100 loads of soil a day for months.
After that, workers would spend about 10 months building the main concrete structure and attaching the granite panels. The schedule then calls for a 300-foot mobile crane after about two years of work, a detail that underlines how much of the job would continue long after the initial excavation is finished. Architects also added aviation safety lighting because the monument would sit near the airport’s flight paths.
That proximity is where the project runs into its sharpest resistance. The Federal Aviation Administration completed a feasibility study and said the arch would have no significant adverse effect on airspace or visual and instrument procedures at Reagan National Airport, and that the only lighting requirement would be red obstruction lights. But the monument is also being challenged in federal court, leaving the plan exposed to another layer of review even as the Park Service presses ahead with public comment and the next aeronautical steps.
The arch is one of several Trump-related projects moving through planning, alongside the White House Ballroom, planned golf course renovations and repainting and sealing the Lincoln Memorial Reflecting Pool. For now, the most immediate question is not whether the monument has a design but whether the public process or the court fight changes where it stands, how it looks or whether a year-round, 20-hour construction schedule survives in its current form.
