Enhancing the Capability of Rapid Bridge Replacement After Extreme Events

Purpose The potential threats of extreme events to highway bridges have received increased attention from government agencies, the engineering and construction communities, and the traveling public. These events include terrorist attacks as well as human‐induced and natural hazards such as earthquakes, explosions, fires, floods, and hurricanes. To respond to the potential threats on highway bridges, a research project was conducted to identify rapid bridge replacement processes, techniques, and needs for improvements. Design/methodology/approach To achieve the research objectives, a detailed case study of previous bridge replacement following an extreme event was conducted. The case study was performed using a three‐step approach. First, the research team reviewed the literature related to the case. Second, the research team interviewed the people who were involved with the case via the telephone. Third, the research team conducted a written survey to gain knowledge about the previously unanswered questions and additional information related to the case. Findings After studying the case, lessons learned were identified first. Then, the research team determined the processes that were used in the rapid bridge replacements and the needed improvements so that the research community could investigate new technologies to advance current practices. Originality/value The lessons learned could be of benefit to government agencies who are responsible for development of the enhanced emergency response plans for highway bridges, and engineering and construction communities who are responsible for design and reconstruction of the damaged bridges. The development of new technologies, if successful, will ultimately enhance the capability of rapid bridge replacement after extreme events
