36000 lbs on a 3 ton rated wooden covered bridge

What happened is exactly what I thought would happen. Lol.

We have one semi locally. It was thumping and creaking with our 4Runner in it. I didn’t particularly care for it.

Here is the Gunpowder covered bridge in my area. It was closed and reinforced and partially rebuilt a few years ago. I don't know the weight limit but it makes a lot of noise going through it.

Just before the driver started across, he probably rolled down the driver's window. It's a good thing since the truck somehow flipped upside down, and he managed to crawl out while underwater. At least he has half a brain.
 
What's nuts is that the front of the truck broke through first, then the entire rig did a "180 pitch"...landing on its back.
Had the truck only pitched 90 degrees, the cab would've been underwater as the load shifted forwards, likely crushing the cab and driver along with it.

I'm told a truck that heavy requires a commercial license. I wonder if the driver had such a license or, possibly, an available employee was grabbed and sent out on this delivery.

Time to break out the insurance policy.

I suspect the front of the truck DIDN'T break through first.

It's pretty clear to me that when the rear axle where the majority of the loaded truck weight was located came onto the bridge deck, it broke through the deck, and fell back-end first into the river, coming to rest as we see in the pictures.
 
That bridge should have been moved either to the left or right of that road by 100 feet or so and only animals and people walking allowed on it. There are plenty of inexpensive used military type steel bridges with weight ratings of 120,000 lbs or more, that could have replaced it.
