I found such a photo on the Internet and became interested in what function such a structure could perform.

    My guess is that it will be a “nature highway” so migratory species can cross over the road

      These are great for wildlife as they provide a safe crossing over high-speed highways. They are usually design to be in already existing migration paths where moving a proposed highway may not work and not disrupting migration paths is of importance.
