this was clearly a faulty structural design. a 174 concrete bridge can not be stable without suspension support or a pillar in the middle. the architects and the engineers should be facing jail time.

Architect here not a Structural Engineer but good golly why was bridge ever put in place without temporary tower and cables in place? That was final design right? What am I missing??

I'm just a dumb contractor. That span sure looks like it should have had a temporary mid-span support until the final cable system was in place...

Yup

The job was not finished when it collapsed. The road should have been blocked until all the work was done. But common sense eluded some people.

What kind of moronic engineer designed this damned thing? Place the center support structure FIRST or shutdown the damned roadway.

For some reason, the Hyatt Regency walkway collapse from 1981 keeps popping up in my head.

Wrong, it was built wrong. We know this because it fell down.

If the bridge was cracked in places then thats the readon for failure but it looks to me as the problem was engineering. Not enough camber to support its own weight let alone with pedestrians. I’m sure someone will notice
-
Camber support? Did you actually read the
@nytimes post?? -
And if I may add “camber” is designed to account for fully loaded, in place, structural deflection — not support. Cite basis of post please.
-
My basis of support is experience erecting over 100 bridges over 50 to 150’. They supported drive units and maintenance crews. I’m not an engineer but just observing what worked for us. Didn’t see final erection drawings in NYT

Suspension bridge is the best solution such an enourmous span.
