A triumphal arch more than 130 feet tall could rise in the heart of Washington next week, and two governments are now racing to stop it in federal court. Virginia and the District of Columbia filed a lawsuit Saturday to block construction of the monument that the Trump administration plans to build on the Potomac River near the Lincoln Memorial.
The suit, filed by Virginia Attorney General Jay Jones and District of Columbia Attorney General Brian Schwalb, asks a federal judge to halt work that officials say is set to begin on Nov. 5. The arch is planned for Memorial Circle, a busy traffic circle where the boundaries of the District and Virginia meet on the Potomac, close to the Lincoln Memorial and Arlington National Cemetery.
The two attorneys general argue the Trump arch would break several federal laws. They point to the Commemorative Works Act, the law that controls what may be built on federal land in the capital, and say the project skips the congressional authorization it requires. They also cite the Height of Buildings Act, which they say the arch would exceed, and the National Environmental Policy Act. In court papers, the lawyers wrote that “the construction of the Arch will inflict immediate and irreparable harm on the District and Virginia.”
What this means for Washington — For residents and visitors, the fight could bring weeks of road closures and added security around one of the most visited stretches of the National Mall. If a judge allows construction to start before the case is decided, the arch could go up before a court rules on whether it was legal to build in the first place. A structure that is already standing is far harder to remove than one that is stopped before it begins.
Why the timing is the whole story
The attorneys general called their request urgent, arguing that every day of delay strengthens the government’s position. They wrote that once construction starts, the federal side would likely argue that halting the work would harm the government, pose security risks, and change the landscape that was “unilaterally created.”
“The Court should not allow this cynical gambit to succeed,” the suit states. The two states are effectively betting that a judge will act quickly, before crews break ground.
The plan sits inside a wider set of Trump memorials and groundskeeping changes around the capital. It follows other contested projects such as a review of Trump’s East Potomac golf-course plan, which drew its own federal inquiry. The courts have repeatedly become the arena where these choices are settled, as seen in a judge’s order blocking DOJ threats to election workers and a ruling that stopped a DOJ ballot challenge in California.
The one detail that changes the meaning of the case is the date. A start date of Nov. 5 turns a slow legal fight into a race, and it forces the court to decide whether to act before the arch exists rather than after.
When could the arch be built? The administration has said construction could begin on Nov. 5, while the Virginia and D.C. lawsuit is asking a federal judge to stop it before work starts. No ruling has been issued yet.
The court has not decided whether to block the project. The outcome will decide whether the National Mall gains a 130-foot arch in days or whether the structure waits for the courts to finish their review. Check back as the case develops.
