HOW THE BRIDGE COLLAPSED

Based on the available visuals and eyewitness accounts, one of the two suspension cables seems to have snapped, triggering a cascading effect that led to the breaking of the deck

Another possibility is that the connections securing the vertical cables with the deck broke, especially at one end of the bridge, letting the unsuspended section with the people on it fall into the river

The bridge was overcrowded

Excessive swaying of the bridge has been suggested as another possible factor that needs to be probed

The original wooden deck was replaced with a heavier aluminium one during recent repairs, but the cables were not strengthened. This caused greater strain on the connecting mechanism
