The 35W bridge collapsed 11 years ago today. Do you remember where you were? Kimberly J. Brown was on the bridge, and she became obsessed with finding out what went wrong--and how to avoid such tragedies in the future. She has a new memoir out on just that subject.

When the I-35W bridge collapsed in 2007, Kimberly J. Brown was inside a car on the bridge. She survived. While recovering from spinal injuries and trauma, she became obsessed with finding the cause of the collapse. KFAI's Emily Bright reports. (CORRECTION: An earlier version of this story incorrectly stated the distance Brown and others fell. PHOTO: Courtesy of Brown's book.) Book info: http://bit.ly/2LPztp0
