The Hyatt Regency hotel walkway collapse was a major disaster that occurred on July 17, 1981 in Kansas City, Missouri, United States, killing 114 people and injuring more than 200 others during a tea dance. At the time it was the deadliest structural collapse in U.S. history. Construction on the 40-story Hyatt Regency Crown Center began in 1978, and the hotel opened on July 1, 1980 after construction delays including an incident on October 14, 1979, when 2,700 square feet (250 m2) of the atrium roof collapsed because one of the roof connections on the north end of the atrium failed. The collapse was the second major structural failure in Kansas City in a little more than two years. On June 4, 1979, the roof of the then-empty Kemper Arena in Kansas City had collapsed without loss of life. The architects and engineering firms at the two collapses were different.
