The dashcam video shows the bridge broke right where the workers were tensioning the cable, so it may have nothing to do with the design.

"The dashcam video shows the bridge broke right where the workers were tensioning the cable, so it may have nothing to do with the design."

Highly likely then! Post-tensioned concrete is all the rage, but it's a risky way to design a bridge. They should have used the older, proven design with the big dowels and non-tensioned rebar for a bridge.

Looked like an awful lot of concrete for a pedestrian bridge, too. Pretty thick. Come to think of it, decking with non-tensioned rebar might have been best for forms, and a thinner slab.

Also, come to think of it, there was no good reason for that heavy slab on top. That should have been some kind of truss bridge sheeted with lighter materials.
