Federal Judge Temporarily Blocks Trump's 250-Foot Washington Triumphal Arch Hours After Key Panel Approves It

The National Capital Planning Commission voted late Thursday to approve final site and building plans for President Trump's proposed 250-foot triumphal arch in Washington, clearing what had been the last major regulatory hurdle for the project. The hearing stretched over nine hours, with more than 100 people testifying in fierce opposition, including members of the D.C. Preservation League, military veterans and families of service members. The commission, whose membership is stacked with Trump appointees, ultimately granted the approval, paving the way for construction between the Lincoln Memorial and Arlington National Cemetery.

Within hours of the NCPC vote, a federal judge issued a temporary order halting the Trump administration from beginning construction. The court challenge, which had been anticipated before the commission met, centers on arguments from opponents including the National Parks Conservation Association, the National Trust for Historic Preservation and the American Institute of Architects, who contend the project lacks required congressional authorization and has not undergone legally mandated reviews.

The arch, which Trump has described as a monument to commemorate the country's 250th anniversary and had earlier said would serve as a military complex housing drones and sniper ammunition, does not include the military functions in the NCPC-approved plans. The administration had signaled it intended to break ground immediately after Thursday's vote, but the temporary judicial block now puts that timeline in question as litigation continues.
