The Federal Aviation Administration said Friday that a proposed triumphal arch honoring President Donald Trump likely poses no risk to aviation safety.

The ruling is a critical step for the project's viability given the monument's proximity to one of the busiest airspace corridors in the U.S. Any structural hazard near the capital could have triggered significant regulatory delays or a complete block of the construction.

The proposed monument would stand 250 feet tall [1]. Because the site is located less than two miles from Ronald Reagan Washington National Airport [2], the FAA requires the installation of red obstruction lights [2] to prevent potential hazards to aircraft.

Construction is slated to occur in seven phases [3] over a period of two to three years [3]. The National Park Service plans for the project to operate 20 hours per day [4].

Location details for the arch vary by report. Some accounts place the monument near the Lincoln Memorial in Washington, D.C. [1], while others describe the site within the Arlington vicinity [5].

While the U.S. Commission of Fine Arts approved the design [1], the project faces political headwinds. A Virginia congressman has introduced legislation intended to block the construction of the arch in Arlington [5].

The proposed monument would stand 250 feet tall.

The FAA's clearance removes a primary technical hurdle, shifting the conflict from aviation safety to jurisdictional and political disputes. The contradiction regarding whether the arch sits in D.C. or Arlington is significant, as it determines whether the project is subject to federal land management via the National Park Service or the legislative interference of Virginia state representatives.
