The White House is pursuing an aggressive construction schedule for President Donald Trump's planned 250-foot triumphal arch near Arlington National Cemetery, with newly released federal documents outlining a goal of completing the project within two to three years.

National Park Service records posted this month show the administration envisions construction taking place 20 hours a day, year-round, through two 10-hour shifts. Construction experts told The Washington Post that such a schedule is unusual for a nonemergency federal project.

The accelerated timeline would allow the administration to complete the monument before Trump's term in office ends.

The project is planned for Memorial Circle, a traffic roundabout near Arlington National Cemetery, and would mark the most significant alteration to Washington's skyline during Trump's presidency.

Documents indicate the arch would be constructed from concrete clad in granite rather than the natural stone used in many of Washington's historic monuments, including the Lincoln Memorial, which experts said could help speed construction.

"He's obviously in a hurry to try to get this all done before he leaves office," University of Maryland architecture professor Matthew Bell told the Post. "Most of the major monuments in D.C. are stone."

The Park Service documents also show the project would require large construction cranes, including one reaching approximately 320 feet and another as high as 300 feet.

The proposed site sits beneath a flight path serving Reagan National Airport, prompting additional scrutiny from aviation regulators.

The Federal Aviation Administration is reviewing whether the arch's planned height poses risks to aircraft operating in the area. In a preliminary report issued last week, the FAA said the structure would require red blinking lights to alert pilots at night. The agency said Tuesday that its review remains ongoing.

White House officials have said construction will begin once all necessary approvals are obtained.

"The Triumphal Arch in Memorial Circle is going to be one of the most iconic landmarks not only in Washington, D.C., but throughout the world," White House spokesman Davis Ingle said in a statement.

Trump has promoted the project as part of the nation's 250th anniversary celebration. The arch has already received approval from the Commission of Fine Arts, while the National Capital Planning Commission is expected to consider final approval as early as next month.

The project continues to face opposition from critics, including veterans groups and preservation advocates. Several military veterans have filed a lawsuit seeking to halt construction, arguing the structure would alter the experience of visiting nearby Arlington National Cemetery.

The Society of Architectural Historians has also spoken out against the plans for the arch.

Its conservation committee recently sent a letter to the National Capital Planning Commission, stating that members believe Trump's arch "threatens to negatively impact the historic and architectural context of its setting, disrupts views to existing significant historic monuments, and runs counter to decades of design and preservation guidance for this area that has been prepared by none other than the applicant itself."

Last week, the Park Service opened a 10-day public comment period on the project, a required step before construction can begin. Comments are being accepted online until June 15 or by email at ncr_planning@nps.gov.

Administration officials have said they will provide at least 14 days' notice before work starts.
