Mr L Neeson of the North Carolina Department of Transport requested this report. The report was needed to provide a progress update and likely outcomes on the investigation into an accident that took place on a bridge over Route 29 highway on 20th May 2000. Although privately owned, the bridge crosses a state highway and it is thus the responsibility of the North Carolina Department of Transport to ensure that a proper investigation into the accident is carried out.
Mr. Neeson’s instructions were to:
• describe the incident itself and the possible causes
• draw comparisons with any other bridge built at a similar time
• draw conclusions regarding: the reasons for the failure of the bridge, the various parties that may be responsible and whether a case should be brought against all or some of the parties
• make recommendations as to what should be done to prevent similar incidents in the future EXECUTIVE SUMMARY
