President Donald Trump has initiated several renovation and construction projects across Washington, D.C., coinciding with preparations for the nation's 250th anniversary. These include a proposed $100 million "Triumphal Arch" near Arlington National Cemetery, the $1.5 million resurfacing and repainting of the Lincoln Memorial Reflecting Pool with a blue hue, and a new 90,000-square-foot White House ballroom, which involved demolishing the East Wing. The ballroom project, costing up to $400 million and funded by private donations, is facing legal challenges regarding congressional approval and was subject to a federal judge's order blocking above-ground construction. Additionally, a rooftop "Drone Port" for national defense has been proposed, and renovations to the Kennedy Center, including painting and refurbishment, were undertaken. A temporary Ultimate Fighting Championship arena was also installed on the South Lawn for events.
