This bit of info stood out to me, ( not an engineer ),

The bridge’s superstructure was something Verrastro said he’s not seen in 42 years of designing bridges. Rather than using steel trusses, it employed heavier concrete trusses. The bridge also had a concrete roof, adding even more weight.

“This was a very long span and then they used very heavy material,” he said. “The majority of pedestrian bridges are steel.” Steel bridges are about one-tenth the weight of concrete, he said.

Liberal morons chose concrete over steel purely for the aesthetics and self-cleaning gimmick - heavier than it needed to be.

For that decision, six people paid for it with their lives. Hey, the bridge would have looked cool!

reminds me of another disastrous collapse involving concrete and new construction practices.https://connecticuthistory.org/the-collapse-of-the-lambiance-plaza/
