Large cracks appeared in the Florida International University pedestrian bridge just days before it collapsed, killing six.
An update from the National Transport Safety Board says their investigation has revealed significant breaks in the concrete emerged after the bridge was moved to its place above the roadway on March 10.
You've got a bunch of engineers saying "This is really bad", and some others saying "Those cracks don't necessarily mean real trouble." I don't have the background to argue either way; I will say that cracks appearing in a main support piece are not exactly confidence-inspiring.
