Morandi Bridge collapse in Genoa Italy

Imagine that. You're driving on the highway, and then, without any warning, the road in front of you just collapses.

It's easy for me to imagine, because I've been on that highway many times. It's in Genoa, Italy. One of the most important roads in the country. This is the road you drive on when you go from Nice (France) to Tuscany, Roma or further South.

One guy stopped barely a few meters from... A sure death. I would be him, I guess I would become a monk.

The most frightening is that there are many bridges on that highway. If one crashed, how to be sure the other ones won't?
