I’ve been to this bridge. It’s the Devil’s Bridge in Wales.

Here’s another angle, ripped from Wikipedia:

The river underneath is insanely deep. Pictures do not do it justice just how much further it goes out of the bottom of this frame. You do not get out of there. That is death.

The bottom-most bridge was built around the 12th century. How the hell they managed to build stuff like this way back then staggers me.

There is nothing more permanent than a temporary solution that works.
