This bridge is not connected to the dam. It's like a half mile away and above the dam. No one is allowed to drive over the dam itself anymore for this very reason.
That's EXACTLY what this is, a FF directed at us.
Fortunately no one can drive a bomb anywhere near the dam anymore.
No.
He is definitely on top of the bridge, NOT THE DAM, I have personally driven over both many times as I'm an AZfag. Notice the picture, the white lane line going under the truck, he's in the middle of two lanes which go the same direction (bridge has 2 lanes going both directions, 4 total). The top of the dam has two lanes total, one going each direction. The dam also does not curve horizontally (deflection) like a bridge does, as seen in the photos.
