- Full DOT permits
- Escorts present
- Didn't hit "a few" and none were "taken out", single glancing impact that resulted in a minor dent on the load
- Bridge listed as "functionally obsolete"
You didn't miss much in your post.
No I didn't miss too much now did I ? I was responding to a comment from a foreigner about just driving across a bridge in the USA and it falling down. Well that didn't happen. The bridge was hit by an oversize vehicle and then it collapsed into the river. I was not doing an in depth detailed analysis of the cause of the bridge failure. I was not there, am not involved in this investigation.
You say it was a glancing blow. The head of the Washington State Patrol says the collapse was caused by the truck hitting the bridge. The NTSB says that there were at least 5 points of contact where the truck hit the bridge. Doesn't sound like "a glancing blow"
We were not talking about escorts, or the fact that the bridge is listed to be replaced. Of course it's listed as obsolete, bridges in good condition do not get replaced. It's just an administrative classification to identify bridges that the DOT desires to secure funding for to replace. In government work, buildings, equipment and infrastructure that is in good order is not generally scheduled to be replaced.
Feel free to investigate and argue with yourself here on out !
