Saw that on a tv show a few years ago.

The bridge has been hit a few hundred times. My town had a bridge like that and they installed radar and warning devices and it still was hit. Then they fixed it by making it taller.

A house moving company was on tv and they said they measure all bridges. The normal height sign has no standard. If it says 12 foot 4 inches then it isn't known if it is that or less or if the measurement is on one side or the other.


Doubt too many got fired.

There was a bridge under I-24 near South Pittsburg (sic...), Tennessee which was also "just a little bit too short." For many years, the exit ramp and roads leading up to the bridge had noisemakers suspended on chains with a sign that said, "Trucks That Hit This Will Hit Bridge."

Eventually, they fixed the problem: they replaced the bridge with one that was of the standard minimum height.

Modern-day mapping and routing software used by trucking companies includes the exact location of every low bridge, every weight-limit, and so on, such that if you describe the nature and weight of the truck it will automatically route around these places. Many on-board GPS units carried by trucks also have similar capability, including the ability to squawk very-loudly to the driver if he is approaching an obstacle that he cannot safely pass or a road upon which he cannot travel. But that doesn't mean that every truck and driver now carries one or has kept its map data up-to-date.
