I literally was holding my breath while watching this video. Fact: I can hold my breath for up to 2 minutes.

This just seems like a really bad idea. I mean I get that you want to show off and cross the bridge, but considering the bridge is made of what looks like plywood it doesn't seem like the best idea. The driver looks shockingly really calm while risking his truck and trailer. I would of definitely decided my best option would be to try to jump the truck and trailer  over the water and hope for the best.
