Trump’s Proposed 250-Foot Triumphal Arch Near Arlington: Design, Defense Claims, and Legal Pushback

President Donald Trump has advanced a plan for a 250-foot “Triumphal Arch” to be erected in the traffic circle where the Arlington Memorial Bridge meets the Virginia shoreline, adjacent to Arlington National Cemetery. The design was first announced in October 2025 as a monument to the nation’s 250th anniversary, but in September the administration re-framed the structure as a “military complex” that could house drones, snipers and ammunition storage.

A to-scale 3-D model created by *The Washington Post* found that the arch’s shadow would fall on burial sites at Arlington on 284 days each year, covering more than 75,000 graves, including veterans from multiple wars and headstones of formerly enslaved people from Freedman’s Village.

In sworn court declarations, Defense Secretary Pete Hegseth and Homeland Security Secretary Markwayne Mullin argued that the arch’s height provides a “significant elevation advantage” for counter-drone sensors and sniper positions. They said the structure could be used by the Secret Service and other agencies to protect senior officials without altering the existing design.

Three Vietnam-era veterans and an architectural historian filed a lawsuit in February, claiming the president bypassed the congressional approval required for new monuments in the capital. U.S. District Judge Tanya Chutkan has ordered the administration to give 48 hours’ notice before any work begins and is hearing arguments on a preliminary injunction to block construction.

The Interior Department’s spokesperson dismissed the *Post* shadow analysis as “flawed,” saying its own modeling showed the arch’s shadow touching only a small part of the cemetery for fewer than two weeks in March. The National Capital Planning Commission, now staffed largely with Trump appointees, is slated to vote on the final plans in November, after which the Justice Department has indicated the administration could begin construction as early as that month.

Retired Army Maj. Gen. Paul Eaton, whose parents are buried at Arlington, called the arch “a sacrilege.” Critics on social media have described the project as an attempt to “overshadow” BIPOC communities, women veterans and historic memorials. White House spokesman Davis Ingle countered that the arch would “enhance the visitor experience” at the cemetery.

*The Washington Post* analysis predicts shadow coverage on 284 days, while the Interior Department’s 23-page simulation suggests impact on fewer than two weeks in March. The methodology of the Interior review has not been disclosed, and the final design submitted to the federal review board makes no mention of drone-detection sensors, ammunition storage or other military features cited by the cabinet secretaries.
