FAA Finds Trump's Proposed Triumphal Arch Likely Safe but Recommends Red Obstruction Lights

The Federal Aviation Administration issued a feasibility study on Donald Trump’s proposed 250-plus-foot “triumphal arch,” less than a mile from Ronald Reagan Washington National Airport. The study concluded the structure would not significantly affect airspace if equipped with red lights. The agency noted the review is limited and a full aeronautical evaluation is required before construction.

The arch is a centerpiece of Trump’s plan to remodel the capital, which also envisions a White House ballroom and a renovated reflecting pool on the National Mall. It would rise on a grass parcel at the foot of Memorial Bridge opposite the Lincoln Memorial. Reagan National’s approach corridor is congested and was the flight path of a midair collision last year that killed 67 people, as well as a 1982 crash into the 14th Street Bridge.

Sources differ on the arch’s height—250 ft, 259 ft, or 279 ft. The feasibility study is a “limited review,” not a definitive hazard determination, leaving uncertainty about required changes to flight procedures.

FAA’s report says the arch is identified as an obstruction and must be equipped with red lights, and clarifies that the feasibility study does not constitute a final determination of no hazard to air navigation. The National Capital Planning Commission voted to advance the project, while the Commission of Fine Arts has not issued a decision.

Experts are divided on impacts. New York Times analysis noted the arch would intrude on airspace that should remain clear for flights. Insiders say panels staffed by Trump loyalists may approve design, regard for risks.

Sources differ on the arch’s exact height—250 ft, 259 ft, or 279 ft including site elevation. The feasibility study is described as a “limited review,” not a definitive hazard determination, leaving uncertainty about any required changes to flight procedures.

If approved, the arch would become a permanent fixture in a critical air corridor, setting a precedent for future tall structures near busy airports. The decision tests the balance between political symbolism and aviation safety.

The FAA must complete a full aeronautical study, after which the National Capital Planning Commission and the Commission of Fine Arts will decide on final approvals. Installation of red obstruction lights is expected if the project proceeds.
