A beautiful bridge

They say beauty is in the eye of the beholder, and I do like bridges.
This one, probably nearly 100 years old, is so delicate considering it has a railway line on the top level, which currently carries the hi speed train between Geneva and Paris, and a single track road on the lower level. You can just see a car, which gives an idea of its size.
Mrs CB and I were on another Groupon extravaganza to the Beaujolais when we came accross it in the Jura mountains.
