The Plan for a Big Arch Next to D.C.'s Airport, Explained Simply
The Trump administration wants to build a 250-foot arch at Memorial Circle, about two miles by air from the main runway at Ronald Reagan Washington National Airport.
Memorial Circle is a traffic island on the old bridge between Washington, D.C. and Arlington, Va. The main runway at Reagan National is one of the busiest runways in the United States NPR.
The administration said the arch would not add risk. An early Federal Aviation Administration report said in June the arch would likely not be a problem if it has blinking red warning lights on top NPR.
At 250 feet, the arch would be less than half as tall as the 555-foot Washington Monument, like a 25-story building next to a 55-story one. The administration has also said cranes used to build the arch could be up to 320 feet tall.
The FAA is now doing a fuller study that could call the arch "a hazard." The agency told NPR in early September that the normal safety review for tall objects near airports is underway for both the arch and the cranes.
NPR talked to three aviation safety experts. It said they agreed the arch most likely would not be a major risk for most planes but would add one more thing to watch in crowded and complicated airspace.
Jeff Guzzetti, a retired accident investigator with the NTSB and the FAA, said "the best option is simply not to build it." Shawn Pruchnicki, a former airline pilot and accident investigator who teaches aviation safety at Ohio State University, said putting a 250-foot arch in Memorial Circle would be "inherently dangerous."
That airspace has been watched closely since the January 2025 midair collision between an American Airlines regional jet and an Army Black Hawk helicopter near DCA killed 67 people.
President Trump first said the arch was for himself and later said it is a tribute to the country's 250th anniversary. The plan has been called the Independence Arch Reuters.
In June 2026, a U.S. senator urged the FAA to reject White House pressure to approve the project Reuters. On June 5, 2026, CNN reported that the FAA had released a feasibility study on the proposed arch CNN.
The broader context here is about process as well as safety. The FAA started with an early check tied to lights and is now doing a full review with a possible hazard finding. That means separate decisions for the permanent arch and for temporary cranes, each with its own safety steps. It also puts more weight on how the agency writes down risk in airspace already marked by heavy traffic, narrow corridors and helicopter flights. That written record, not early statements from supporters or critics, will likely shape what Congress, the courts and operators do next.
