Love, pushing two empty barges owned by the Magnolia Marine Transport Company of Vicksburg, Mississippi, was moving upstream on the Arkansas River when it hit the I-40 Webbers Falls Bridge around 7:47 am. On the Memorial Day weekend of May 26, 2002, the towboat Robert Y. This paper presents the I-40 Webbers Falls Bridge case in Oklahoma and lessons learned from this incident. At the end of each case study, a report was generated including the lessons learned. Fourth, the survey results were easy to compare and ana- lyze. Third, the survey gave people more time to respond to the questions as compared to personal interviews. Second, the survey questionnaire provided, in general, a very clear statement of the problems. First, the survey was a relatively easy way to solicit answers to the same questions from several people. There were several reasons for choosing the survey method to acquire knowledge. The survey questionnaire consisted of five aspects, including contracting method, engineering, construction, state DOT support, and material supplier and vendor support. The third step was to conduct a survey comprising the previously unanswered questions and additional needed information related to each case. After the first two steps, the research team had an initial understanding of each case, and unanswered questions were clearly outlined. In these telephone interviews, researchers asked them a series of questions regarding their roles and knowledge about the case. These people came from state DOTs, design firms, contractors, and material suppliers. Second, the research team interviewed the people who were involved in the case via telephone. First, the research team reviewed the literature related to the cases, including newspaper articles, conference and journal papers, technical reports, and Web sites. Case studies were conducted using a three-step approach. By studying previous cases, the research team sought to identify and expand on lessons learned, address which actions did and did not work well given the circumstances of the incident, and incorporate these lessons into an emergency response plan for highway bridges. A case study method- ology was utilized to accomplish this objective. The objective of this research was to identify strategies and technologies to quickly restore highway bridges, a critical component of the nation’s transportation network, to their use in case they are damaged or destroyed by extreme events. The reasons for which these bridges were chosen were that all were critical components in the nation’s interstate system and the incidents had significant impacts on the traveling public and surrounding communities. Dewey Thruway Bridge in New York in 1997, and the I-40 Webbers Falls Bridge in Oklahoma in 2002. They were the I-95 Chester Creek Bridge in Pennsylvania in 1998, the Governor Thomas E. The research team reviewed 26 bridge incident cases in the United States and overseas and identified three cases on which to perform detailed studies. These events included explosion and fire caused by roadway vehicle impact, waterway vessel collision, flood damage, and earthquake damage. One of the tasks associated with the research project was to conduct several case studies of previous bridge replacements following extreme events. Other entities participating in the project were the state DOTs of Georgia, Illinois, Minnesota, Mississippi, New Jersey, New Mexico, Ohio, and South Carolina. A pooled-fund research project, led by the Texas Department of Transportation and titled ”Rapid Bridge Replacement Techniques,” was conducted beginning in March 2002. Highway bridges, as a critical component of the nation’s transportation network, have been brought to closer attention by government agencies. systems have presented an urgent need for government agencies such as state Departments of Transportation ͑ DOTs ͒ to develop emergency response plans to quickly react to the possible consequences of an extreme event.
