On October 30, 2019, a fire broke out in a homeless encampment beneath the I-29 northbound bridge over Perry Creek in Sioux City, Iowa. The fire intensified when a propane tank became engulfed in the flames.
The incident gave Iowa DOT a real-life case study to better understand how visible damage may correlate with a bridge’s serviceability and strength, as well as an opportunity to update the agency’s tools and resources for evaluating fire damage in the future.
The research results can help guide Iowa’s state and local transportation agencies as they make repair or replacement decisions for a bridge that’s damaged by fire.
