I have seen articles saying the bridge has been struck many times, and never had damage. The difference is, the truck had a rather solid steel load that struck the bridge. Not a corner of an aluminum sheet metal trailer.
The bridge sufficiency is a method of evaluating highway bridge data by calculating four separate factors to obtain a numeric value which is indicative of bridge sufficiency to remain in service. The result of this method is a percentage in which 100 percent would represent a entirely sufficient bridge and zero percent would represent an entirely insufficient or deficient bridge.
Sufficiency Rating is essentially an overall rating of a bridge's fitness for the duty that it performs based on factors derived from over 20 NBI data fields, including fields that describe its Structural Evaluation, Functional Obsolescence, and its essentiality to the public. A low Sufficiency Rating may be due to structural defects, narrow lanes, low vertical clearance, or any of many possible issues.

Aren't drivers aware of this:
A “fracture critical” bridge is defined by the FHWA as a steel member in tension, or with a tension element, whose failure would probably cause a portion of or the entire bridge to collapse.
Fracture critical bridges, of which there are a total of about 18,000 throughout the U.S., lack redundancy, which means that in the event of a steel member’s failure there is no path for the transfer of the weight being supported by that member to hold up the bridge. Therefore, failure occurs quickly, as reflected in the video that captured the collapse of the I-35W Bridge in Minnesota.
