Overview
- As of Aug. 7, the National Gallery of Art said it completed an extensive vibration study and has installed measures such as boarded skylights and protective barriers to protect staff, visitors, the collection, and outdoor sculptures.
- The Smithsonian told reporters it will take no extra precautions and said its artifacts are not expected to be endangered by the race route that passes by several of its museums.
- Organizers and city officials have finished or are finishing road resurfacing and course build-out on a roughly 1.66–1.7 mile, seven-turn circuit where cars may reach about 185 mph, and D.C. Police have issued traffic advisories and early road closures for the Aug. 22–23 weekend.
- Preservation experts warned that high speeds and vibrations could threaten delicate works and monuments, while organizers pointed to prior monitoring—including a 2023 Art Institute of Chicago study—and said they followed protocols and do not anticipate structural impacts.
- What to watch next: the final permitting and security plans, continued build-out on the Mall, and the race’s potential effects on museum access, neighborhood traffic, and public costs as the event approaches.
