If this is the case, then the title of the thread is actually misleading because the bridge then is not tough at all; the i-beam installed BEFORE the bridge is the robust part. This also infers that either the bridge was knocked loose in early collisions, or that the engineers knew the bridge was not tough enough to take the impact from the beginning and gave it protection (a bridge condom of sorts I guess).

And yes I have been told I would make a great lawyer!
In a lot of ways this is like Frank Loyd Wright's famous (or infamous) Falling Water house. One of the construction workers, a rather tall fellow, hit his head on a protrusion and gashed his head open. When the famous architect heard of this incident and was asked for a suggested fix, he screamed out in anger, "I do not design my buildings for freaks." His attitude was just as bitter when workers told him the cantilevered section over the water falls should be reinforced. Again he scoffed, yet when the Department of the Interior did a major renovation to the structure a few years ago, they had to strengthen the supports to the cantilevered section because it was sagging beyond allowable limits.
I realize the shock value of this video, but in reality this bridge is poorly engineered. I know, I am a stick-in-the-mud, but a well designed bridge would never be hit in the first place, or if a bridge continued to be hit a lot, it should be retrofitted so that it does not pose a problem. Putting a well mounted I-beam in front of it must have been done by the Maine Department of Transportation who are well versed in putting up signs that say, "Rough Road Ahead", but while they will go to the effort to do that, it would take just as much time and effort to just fill the pot holes.
I wonder if they will video tape the police officer telling the truck drivers wife that her husband, and father of three children, who just got killed by hitting a low bridge because he was not familiar with the road? Look at the majority of trucks that are hitting it; rental trucks who would be people moving into new homes and not familiar with the area, or people driving trucks who aren't familiar with increased truck heights. An even more likely scenario is that part of a truck has sheared off and landed in the car seat of a two year old in the car behind the truck.
I cannot fathom the liability that this bridge has, considering they have taken the time to put up video cameras to tape the resulting, and predictable carnage. A ambulance-chasing-attorney would do well if a fatality should ever occur.
