AvE did a youtube video with his community's theory/analysis. The original plans for installation showed the temporary supports under the bridge in different locations vs where they were when it failed. Also, you can see one of the prestressing tendons sticking out of the collapsed structure with the tensioning cylinder still attached. AvE thinks someone got the math wrong when they changed the location of the supports during installation. When they put too much stress on that tendon, it stretched. Then, when sensors showed lower tension on that tendon, they tried to pull it tight again, causing it to snap.
