Burgum says excavation for the 250-foot Washington arch starts within two weeks

Interior Secretary Doug Burgum said on 3 September that excavation for a 250-foot memorial arch on Columbia Island will start within two weeks. The site sits between the Lincoln Memorial and the ceremonial entrance to Arlington National Cemetery. Final approval from the National Capital Planning Commission has not been granted. The commission cleared the site and preliminary plans in July and is due to take the file up again this autumn.

Burgum posted renderings of a white arch with gold detail and the words "ONE NATION UNDER GOD." A winged figure with a torch stands on the crown, with eagles at the sides. "This will be one of the Great Pieces of American Architecture, befitting the most powerful Capital in the World," he wrote on X. President Donald Trump has said the finished work will surpass the Arc de Triomphe in Paris and will mark the 250th anniversary of American independence. In June he called it, without qualification, "the Greatest Arch of them all."

The published plan is aggressive. Construction is split into seven phases. Crews are scheduled to work up to 20 hours a day, year-round, with a target of two to three years. The building would have three levels: a ground floor for security screening, a mezzanine with restrooms, and an observation deck. The Department of the Interior says the arch would improve the visitor approach to Arlington National Cemetery and serve as a reminder of military dead.

The legal path is thinner than the renderings. The administration has argued that Congress approved a similar monument more than a century ago and never built it, and that this history covers the present project without a fresh statute. Surveying and geotechnical work began in mid-May under an existing AECOM contract, a route that avoided a new public bid. The U.S. Commission of Fine Arts, whose sitting commissioners were appointed by Trump, has given early design approval. The National Capital Planning Commission has not given the last word.

Veterans have sued, saying a commemorative work of this scale on that ground requires Congress under the Commemorative Works Act of 1986. Justice Department lawyers are now pointing to a 5-4 Supreme Court ruling issued on Monday that dismissed a preservationist challenge to the White House ballroom for lack of standing. They want the arch case thrown out on the same theory. Public polling cited in coverage of the announcement shows a majority of Americans oppose the project. Sightline critics say a 76-metre structure on Memorial Circle will break the long view from the Lincoln Memorial across the bridge to Arlington House.

Columbia Island is not an empty lot. The Army Corps of Engineers expanded and raised it between 1925 and 1928 for the Memorial Bridge project. Boundary Channel Bridge and Memorial Drive were finished in the early 1930s. The traffic circle that now sits on the island links the bridge, the George Washington Memorial Parkway, and the road into the cemetery. A scaled model of the arch was shown on the National Mall on 24 June when Trump opened the Great American State Fair as part of the 250th anniversary program.

Burgum's calendar puts machines in the dirt before the planning commission votes and while the veterans' case is still live. That sequence is the story. The administration is treating excavation as a fact on the ground rather than the last step after permits. If a court later stops the work, the island will already have been cut. If the work continues, the view from the Lincoln Memorial will change on a timetable set by a social media post rather than by a statute.
