The Federal Aviation Administration (FAA) has announced that Trump’s proposed arch structure would require modifications to meet safety regulations for flights arriving and leaving the nearby Ronald Reagan Airport (DCA). On top of potential safety concerns, there has been some public opposition regarding the appearance of the skyline and the lack of due diligence following project approval regulations.
Safety Precautions for The “Independence Arch”
Last month, the FAA announced it would be evaluating the arch structure proposed by President Donald Trump in order to assess any potential hazard the structure might pose to a direct flight path in Washington. Trump expressed that he wanted the Arch to be built in across from the Lincoln Memorial near Arlington National Cemetery, located 3,000 feet from a key arrival and departure corridor to Ronald Reagan Airport (DCA). This particular flight path is already well known for being a tight squeeze between existing architecture, and the structure, labelled the “Independence Arch” by the White House, would stand at 250 feet high, indicating potential disruption. To ensure safe passage to and from DCA is maintained, the Trump’s planned arch would require modifications.
So far, the preliminary review of the planned arch asserted that the structure would require blinking safety lights, but does not pose any major risk to the flight traffic. The FAA does typically require any large structure over 200 feet high nearby to an airport to have red warning lights, in order to to warn pilots at night of their presence. One example of such this is the Washington Memorial nearby, which is 555 feet high.
The structure was suggested by Trump in October 2025 as a celebratory symbol of the U.S.’s 250th birthday. Its design has been described as reminiscent of other great arch structures around the globe, but would become the largest if it is built according to current plans, with the Arc de Triomphe in Paris standing at 164 feet high and the Monumento a la Revolución in Mexico City measuring at 220 feet. On June 4, the National Capital Planning Commission advanced the project while simultaneously requesting further information about the structure’s likely impact to flight paths.
Controversy Could Cause More Modification
“That sightline was carefully designed to symbolize the unification of the country after the Civil War and the strength of a united nation. But with the erection of this Trump vanity project, Arlington House will no longer be visible from the Lincoln Memorial, and the view of the Lincoln Memorial from Arlington House will be obscured, disrupting the historic and symbolic link between the two.”
The FAA announced that it begin the next step of conducting a full aeronautical study in coordination with the National Park Service in relation to the risks associated with the construction of the arch.
