US President Donald Trump is moving forward with plans to build a monumental arch in Washington, DC, even as preservationists and aviation experts warn the project could face serious legal and safety obstacles.
The proposed structure, known as the Independence Arch, is intended to mark the United States’ 250th anniversary. At 250 feet tall, it would surpass Paris’ Arc de Triomphe and become the largest monumental arch in the world, standing roughly as high as a 16- to 20-storey building.
Trump has personally championed the project, describing it as a future global landmark. The design includes a stone arch topped by a 60-foot gilded Lady Liberty statue, with decorative columns, eagles and wreaths. Smaller versions were reportedly considered, but Trump is said to be firmly committed to the largest option.
The planned location, a traffic circle at the base of the Arlington Memorial Bridge has drawn sharp criticism. Preservationists argue the structure would obstruct the historic sightline between the Lincoln Memorial and Arlington House, a view regarded as symbolically important to American history.


Architectural historian Bryan Clark Green said the scale of the project is the main concern. While not opposed to a monument at the site, he warned that the arch would dominate its surroundings and overwhelm nearby landmarks.
Beyond visual impact, aviation safety has also emerged as a major issue. The proposed site lies close to flight paths into Ronald Reagan Washington National Airport. Aircraft approaching from the north pass the area at low altitude, raising concerns that the arch could reduce safety margins in already congested airspace.
Although federal planning commissions are expected to review the proposal, the project is not exempt from environmental and historic preservation laws. This means additional assessments and public consultations will likely be required, potentially delaying construction.
Legal experts say lawsuits are almost certain if the administration moves forward without following established review processes. Critics argue the project’s size, location and potential impact on historic resources make it vulnerable to court challenges.
