ST. LOUIS — Following guidance from the National Park Service, a new mask mandate went into effect on Tuesday, December 27, 2022, regardless of vaccination status for anyone entering federal buildings, which include the Gateway Arch itself, at Gateway Arch National Park.

According to the CDC, St. Louis City and St. Louis County are at a High (Red) level due to increased community transmission of COVID-19. All staff and visitors must wear a well-fitting, high-quality mask, defined as “a surgical mask, procedure mask, an internationally approved device (e.g., KN95s and KF94s) or respirator.” Cloth masks and similar face covers (e.g., gaiters) are not considered high-quality masks. Surgical masks are available to visitors at the Arch Information Desk free of charge.
