They keep saying the bridge collapsed, like it failed. It seems to me like it got hit by a truck, violating its structural integrity.
I was thinking, maybe they should do like McDonalds drive thru and hang a pipe about 1/4 mile before the bridge, so if a truck smacks the pipe they know they won't fit the bridge.
Low tech! Yes, No? Maybe so?
But it would probably cost about $50,000 to hang up a pipe.
