It seems that there are quite a lot of "devils' bridges" all over the world and they have a sad story to tell as these are the bridges that get used most for suicide attempts.
It's the closest of the 3 bridges that is the pont de diablo and I think the 2 small arches look like eyes and the main span of the bridge resembles a howling mouth (a bit)
Anyway nobody jumped today !
C and C most welcome
