I drive over this bridge several times a week on the bus. A while ago I noticed that there's a jogging/hiking/skiing trail underneath. One evening I packed my gear and headed for the destination. I was half right and half wrong: there is indeed a passage you can use to hike or whatever BUT the side I was using to get there is not maintained during winter.. I really had to work (and cuss a tiny bit) to get there. However, I'm quite happy with the results, so I'd say it was all worth it. Besides, very often going out for a proper sweaty walk or a climb is waaay better than just lying around at home.
Here you can find my previous fooleries with camerathings.
Thanks for visiting!
