Here is the next Interstate bridge that will probably fall into the water. 
The old I-10 bridge in Lake Charles, LA

Mental note to self: don’t go to LA.

That is frightening.

Look at the bridge shoes (lowest visible steel atop the piers) for the main span.

Those four locations support not only the main span, but also half to all (depending on how the cantilever trusses are designed) the weight of both of the next two approach spans, plus any live load (vehicles) those three spans of the bridge are carrying.

That translates to significant (massive) point loads at those locations.

I agree with you about that bridge in Lake Charles.

I drove a big RV over it one time going to Breaux Bridge for the crawfish festival.

I came back by a different route.

Why do you think that bridge in Lake Charles will go?

I drive over a bridge daily over a little creek, Jones Creek, and the levels of the water rise dramatically with rain, all the way to the roadway. It scares me,,I just don’t think that bridge can withstand that kind of water coming up so much. Usually the water line is a good 20 feet below the road.

But what is it about that bridge? I drive over it from time to time.
