Just saw this on the 10:00 news.
No wonder why for some years now dump up alarms & light on the dash are required for dump trucks !

This was in Turkey, but I remember this happened on rt 495 about 5-10 years ago

Wow.

I can only speculate, but I'd imagine if you drive a truck for a living, it must feel different with the bed up in the air like that. Amazing that the two people on the bridge were only injured looking at the destruction.
