Hurricane Katrina Report Examines Damage to Bridges
Damage to Bridges from Wind, Storm Surge and Debris in the Wake of Hurricane Katrina by Jerome S. O’Connor and Paul E. McAnany, focuses on the structural performance of bridges based on findings from reconnaissance trips to the coast of Mississippi and adjoining areas of Louisiana and Alabama. The first investigation took place September 6-11, 2005, about a week after the event, with the second following a month later, in October 2005.
The report includes an overview based on an aerial reconnaissance flight over the Mississippi coast, and provides a photographic essay documenting conditions at a variety of sites throughout the area.
The most severe damage was found near Biloxi Bay, St. Louis Bay, and Lake Pontchartrain. Katrina’s intensity lifted water levels to unprecedented elevations, which created a scenario that was not envisioned when the bridges were designed and built. Structural failures resulted primarily from wave forces and debris hitting bridges.
The report, MCEER-08-SP05, is the fifth and final volume in the Hurricane Katrina report series. It can be ordered online for $35.00. Screen quality versions of the Hurricane Katrina reports are also available.
