Someone else posted the NTSB video on the bridge: https://www.youtube.com/watch?v=J-VnWB4fiFk https://www.youtube.com/watch?v=J-VnWB4fiFk I am fairly certain that a large majority of people, if they'd have had access to those images of the bridges structural members, would have stopped using it.

Most people are unable to accurately diagnose a bridge structure other than "yeah looks rusty". And if that were the case, they wouldn't be driving much of anywhere in that part of the country, which is called the "rust belt" for a reason. Pittsburgh has a very high number of bridges, if you go anywhere in that city and you don't want to cross a rusty bridge, you can't go very far.

  There's rusty, and then there's "I can see daylight through the steel". I think most people can accurately diagnose that as an actual, real problem.

    That isn't an uncommon sight around Pittsburgh. Whether or not it is an imminent structural issue depends on where the holes are.

      This one settled it for me: https://youtu.be/J-VnWB4fiFk?si=BHg_ppZIAb2ykU2-&t=301 https://youtu.be/J-VnWB4fiFk?si=BHg_ppZIAb2ykU2-&t=301 It's an important enough member to warrant 10 (I am assuming symmetry here, you cannot see all of them) not quite tiny bolts and nuts, but you can see clearly through the thing.

        Check out a few of the bridges rated poor on this map: https://gis.penndot.gov/paprojects/BridgeConditionsMap.aspx https://gis.penndot.gov/paprojects/BridgeConditionsMap.aspx ... and find some that pass over other roads, and you can find other instances: https://www.google.com/maps/@40.4562613,-79.9736136,3a,52.6y,350.46h,137.6t/data=!3m6!1e1!3m4!1sITYjFZyz9dVyoOmhmy9zSg!2e0!7i16384!8i8192?coh=205409&entry=ttu https://www.google.com/maps/@40.4562613,-79.9736136,3a,52.6y...

The "rust belt" used to be the "steel belt", until free trade agreements made the US steel industry non-viable. Rust is symbolic of that decay. All of the infrastructure that was built when these areas were economically solid, is now rotting along with the economy that built them.

    "rust belt" is often used collectively to describe all of the decay in the region, not just the decrease in industry. As industry pulled out of the region, a lot of infrastructure deteriorated with it.
