Considering that the trailer was empty, I'm guessing that little if any damage was done to the bridge. Notice in the end of the video how the loss of the roof caused the floor to buckle. Modern box trailers are really flimsy, the result of weight savings in construction. The trucking company is out one reefer, plus the clean - up costs, plus the towing bill for the reefer, plus they'll probably be seeing the local PUC inspectors REAL SOON. The driver will no doubt be applying at his local Jiffy - Lube real soon, plus he got all those dirty looks from the motorists whose commute he screwed up !!!
