The Las Vegas Convention and Visitors Authority is marking America250 with a summer-long series of high-profile patriotic activations that highlight the region's role in the American story.

Memorial Day marked the launch of Southern Nevada's America250 programming at Hoover Dam, where Nevada and Arizona leaders unveiled a 300-foot-by-150-foot American flag and nightly red, white, and blue illumination across one of the nation's most iconic landmarks. While weather conditions may require the flag to be lowered temporarily, the lighting display will continue nightly at dusk through July 4.
