Proposed arch in the path of air traffic

The current proposal for the arch sets the height at 288 feet above sea level. The New York Times mapped air traffic in the Washington, D.C. area to show why that’s an issue.

Among maps that show flight paths from above, a view from ground level shows how close flights from April 2026 would have gotten if the arch existed. The view rotates 360 degrees and makes the distance from arch to air traffic more obvious.
