President Donald Trump’s planned 250-foot triumphal arch near the Lincoln Memorial would be built on an intensive, year-round schedule with two 10-hour shifts per day, according to a preliminary assessment by the National Park Service.
Tower cranes up to 320 feet tall, forklifts, concrete pump systems, and other heavy equipment would be needed to construct the arch, which would tower more than twice as high as the Lincoln Memorial. The 24-page assessment was released last week as part of a fast-tracked historic preservation review.
The planned site for the arch, across the Potomac River from the Lincoln Memorial in Washington DC, sits on a flight path near Ronald Reagan Washington National Airport. The Federal Aviation Administration has begun reviewing whether the project’s height poses a risk to air travel — a particularly sensitive question after an American Airlines jet and an Army Black Hawk helicopter collided in crowded skies near the airport just over a year ago, killing 67 people.
The FAA has preliminarily found “no adverse impacts to operations” but determined the arch’s top would need red obstruction lights. A full aeronautical study is underway.
Pushing the Limits
The National Capital Planning Commission voted last week to seek more information from the Interior Department, keeping the project alive while officials study potential impacts on air travel, construction logistics, and traffic. The U.S. Commission of Fine Arts has already approved the arch’s design.
Will Scharf, Trump’s White House staff secretary who heads the commission overseeing the project, has argued that a federal law limiting building heights in Washington to 130 feet should not apply to the arch. The structure would be nearly double that limit.
Critics say the arch would dominate the DC skyline and disrupt the carefully designed views between the Lincoln Memorial and Arlington National Cemetery. It would be close to half the height of the Washington Monument, which stands at about 555 feet.
A group of veterans and a historian have already sued the Trump administration in federal court to block the project over concerns about disruptions to the sightline.
The Cost and Timeline
Trump has pushed for the arch to mark America’s 250th anniversary, saying the project could be paid for with private donations left over from the new White House ballroom. A cost estimate is still being calculated, but a mix of taxpayer and private funds is expected to pay for it.
Preliminary surveys and testing of the site began last month. The park service report outlines an aggressive schedule: construction would occur year-round in two 10-hour shifts per day, with tower cranes and heavy equipment operating continuously.
Legal and Political Pushback
Democratic Sen. Richard Blumenthal of Connecticut criticized the administration’s “persistent lack of transparency” in advancing Trump’s Washington-area construction projects. Besides the arch, Trump is renovating the Lincoln Memorial’s Reflecting Pool and rebuilding a public golf course along the Potomac River. None of the projects have gone through usual legal reviews or Congress.
“Your disregard for legal process and public interest has been apparent,” Blumenthal wrote in a letter to Interior Secretary Doug Burgum and the acting park service director.
The Bottom Line
The Trump administration is pushing forward with plans to build a 250-foot triumphal arch near the Lincoln Memorial in Washington DC, with an intensive year-round construction schedule of two 10-hour shifts per day. The arch would more than double the city’s 130-foot height limit and has raised concerns about aviation safety, historic sightlines, and legal process. The FAA is reviewing the project’s impact on air travel, veterans have filed a lawsuit to block it, and Democratic lawmakers are accusing the administration of bypassing standard reviews. A cost estimate is still being calculated, with a mix of private and taxpayer funds expected to pay for it.
