Abstract. This paper addresses the issue of progressive collapse in bridge structures. It analyzes the causes and types of progressive collapse based on a review of both foreign and domestic literature. Methods for preventing accidents caused by progressive collapse are presented. During the design phase, this includes identifying key elements within the system and enhancing their strength, analyzing various scenarios that could lead to an accident, and limiting damage to a specific area. In the operational phase, options for monitoring bridge structures are discussed, as well as the construction of parallel structures to distribute loads. The paper examines several bridge failures: improper dismantling of construction structures in China, the collapse of a pedestrian bridge in India, and the failure of a vehicular bridge in China due to misuse, as well as the destruction of a metro overpass in Mexico due to construction errors, and a bridge collapse in Florida resulting from design flaws. Additionally, it addresses failures of supports due to environmental factors and human errors in Scotland. In conclusion, measures to prevent accidents caused by progressive collapse are proposed. These measures, applicable during both the design and construction phases as well as during operation, emphasize the importance of thorough monitoring at each stage of a bridge’s lifecycle.
