Hard bridges?

I guess it wasn’t easy to figure out what bridge it was in the pictures of the advent calendar. I will now give a clue about three days after I posted the picture so you might get it as long as it hasn’t gotten three (3) right answers here as a comment to the post. So you might want to check back a few days and continue guessing. So far there aren’t three right answers on any of the bridges I’ve posted.

The last bridge with clue is this one: 3d December Bridge Tomorrow there will come a new clue…

Good luck!
