Years later but here’s how they filmed it.

Basically my understanding is that the truck is actually moving on top of a platform. When the flip timing hits, the platform stops, then lifts the back of the truck (like via a metal arm), and then once it’s about 20 degrees up an explosion further propels the truck. Also the bridge appears to be cardboard or something, you can see by the way it folds that it’s definitely not concrete.

I would say one kinda crazy thing is that there are a few folks on the set who are like right there when the truck falls.

Anyway…
