This report reviews the procedures that state departments of transportation and two local authorities, New York City and Los Angeles County, use to assess the damage in bridges in response to extreme events and conduct the emergency response activities. Extreme events include those with geological sources (such as earthquakes and landslides), of hydro-meteorological sources (such as hurricanes and floods), or those of man-made origin, either accidental (such as truck crashes) or malicious (such as terrorist attacks). The study found that collision (mostly over-height vehicles) is the number one source of failures in bridges followed by those caused by hydraulic sources such as scour and flood and debris flow. Visual inspection is the first tool for assessing damage to bridges. Bridge engineers use other techniques for assessing damage, such as non-destructive testing and sonar surveys. Most states have emergency response plans for extreme events. Follow-up interviews, however, found that not all of the response plans are tailored for response to bridge damage.
