Key facts
- The proposed arch would be 250 feet tall, 100 feet taller than the Statue of Liberty.
- The arch site is located on an island that straddles the Potomac River, connecting D.C. and Virginia.
- Construction is expected to cause traffic snarls, pollution, and interfere with emergency services.
Virginia and Washington D.C. filed a federal lawsuit on Saturday, arguing that construction of Donald Trump's proposed 250-foot memorial arch would cause irreparable harm to traffic, pollution, and emergency services. The attorneys general for both jurisdictions are seeking a temporary restraining order to halt the project, which the administration says could begin construction as early as next week. A federal judge is already considering a similar request in a separate lawsuit filed by veterans and an architectural historian. The proposed arch, intended to be taller than the Statue of Liberty, would be situated on a patch of grass off a bridge spanning the Potomac River, a key traffic artery between the city and Virginia.
