"In a 2010 evaluation, the group said the bridge is "somewhat better than minimum adequacy to tolerate being left in place as is."
"However the bridge did not make the Washington Department of Transportation's list of "structurally deficient bridges."
I heard on NWCN that an oversized truck taking out part of the overhead truss superstructure was the probable cause of the collapse. That such a simple thing could take it out is a problem but it sounds like the bridge was basically sound.
