Great video and great editing! You managed to capture every aspect of both the bridge intact and collapsed in just 55 seconds. :3

Why did the bridge collapse?

The National Transportation Safety Bureau (NTSB) believes that this truss bridge design was flawed, as the gusset plates were only half the thickness they should have been for the load. Also, the design had no redundancy -- if one part fails, the whole thing collapses.
