The U.S. Commission of Fine Arts is scheduled to review President Donald Trump's design for a triumphal arch on Thursday, along with several other projects aimed at leaving a lasting mark on Washington's federal buildings and monuments.

The proposed arch would stand 250 feet tall on a human-made island in the Potomac River at the end of Memorial Bridge from the Lincoln Memorial. The structure would feature a Lady Liberty-like figure holding a torch at the top, flanked by two eagles and guarded at the base by four gilded lions. The phrases "One Nation Under God" and "Liberty and Justice for All" would be inscribed in gold lettering on the monument. White House press secretary Karoline Leavitt said the 250-foot height honors America's 250 years of existence.

The commission, whose seven members were appointed by Trump, will also consider plans to paint the gray granite exterior of the Eisenhower Executive Office Building white and review designs for an underground visitor screening center. The Executive Office Building, completed in 1888, is a National Historic Landmark featuring French Second Empire architecture that currently houses offices for the vice president and National Security Council.

The projects face legal challenges. A group of veterans and a historian have filed a federal lawsuit to block the arch's construction, arguing it will disrupt the sightline between the Lincoln Memorial and Arlington House at Arlington National Cemetery. The proposed building paint job is also subject to litigation.

The underground screening center would be built beneath Sherman Park southwest of the White House, providing 33,000 square feet of space with seven processing lanes for tourists and visitors. Officials want the facility operational by July 2028. The National Capital Planning Commission opened consideration of the visitors' center last month and is expected to receive the arch design for review soon.

Trump described the arch on social media as what "will be the GREATEST and MOST BEAUTIFUL Triumphal Arch, anywhere in the World" and a "wonderful addition to the Washington D.C. area for all Americans to enjoy for many decades to come."
