Where Is This?

[glatt]

It's a park, so they put a road through the gap instead of just going around the rock outcropping because it's a cool feature to see. But the gap is too narrow for two-way traffic, and there is a blind curve on either side of the gap, so cars don't see each other until it's too late for an inattentive driver to yield to whichever direction has the right of way. So road engineers made an elaborate loop-dee-loop to get all traffic to go through the gap in the same direction.

They could have gone around the gap and saved a lot of effort and money, but in a park, it's about pleasure and scenery, not practicality.
