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

    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.

      It’s also amazing visually! Forget regular highways! Let’s have buried highways! That’s especially good for if our country is invaded because we can install physical barriers to logistical supply lines against us!
