- The agency stated the arch does not pose a safety impact to traffic at Reagan Washington National Airport.
- The proposed structure is located within the airport's main approach and departure corridor.
- A full aeronautical study is pending, to be conducted with the National Park Service.
- A lawsuit has been filed to block the project, arguing it would harm a protected historic landscape.
The Federal Aviation Administration (FAA) has issued a preliminary assessment for President Donald Trump's proposed 250-foot Independence Arch in Washington, stating it would require red obstruction lights but would not impact traffic safety at nearby Reagan Washington National Airport.
The FAA's review noted the arch's proximity to the airport's flight paths, approximately 3,000 feet away, and indicated that red warning lights, typically required for structures over 200 feet near airports, would be necessary. A comprehensive aeronautical study is planned in conjunction with the National Park Service.
The proposed arch, envisioned to be taller than the Lincoln Memorial and comparable in size to the U.S. Capitol, has faced scrutiny. The National Capital Planning Commission recently advanced the project while seeking further details on its impact on flight paths. Additionally, a lawsuit has been filed, contending that the structure would harm a protected historic landscape and that congressional approval is required for major new constructions on federal land in Washington D.C.
