Elefants on the Bridge

Stumbling, I found this interesting photo:

 and could not believe my eyes. Is it a true photo or a collage? I could ot understand but than I had these ideas "contro":
The bridge seems to be not adapt for the place.
The elephants have nothing to do in such places even if guided by the humans that seem to be less intelligent than animals.
Animals would not go all together on that bridge, I think.

Do you think, I'm right?
