Prestressed concrete is a form of concrete used in construction which is "pre-stressed" by being placed under compression prior to supporting any loads beyond its own dead weight.: 3–5 This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete volume, and is done to improve the performance of the concrete in service..

From the concrete pour sequence we know that at the ende of 11 and 12 there is a cold joint in the concrete near the deck (not great in shear) and not a lot of mild steel reinforcing to transfer shear - this joint in my opinion definitely failed and caused the collapse. Not enough normal reinforcing to result in a more elastic failure..
