Emergency medical services response to a major freeway bridge collapse.

BACKGROUND The Interstate 35W Bridge in Minneapolis collapsed into the Mississippi River on August 1, 2007, killing 13 people and injuring 127. METHODS This article describes the emergency medical services response to this incident. RESULTS/DISCUSSION Complexities of the event included difficult patient access, multiple sectors of operation, and multiple mutual-aid agencies. Patient evacuation and transportation was rapid, with the collapse zone cleared of victims 95 minutes after the initial 9-1-1 call. A common regional emergency medical service incident management plan that was exercised was critical to the success of the response. CONCLUSIONS Communication and patient tracking difficulties could be improved in future responses.
